Force Sensors Automate Safety Systems in Industrial Facilities

Automation has become a critical facet of the industrial sector as companies utilize robotics, cobots, IoT, and other sensing technologies to improve efficiency and output. However, production is not the only area of manufacturing benefiting from automation.

Worker safety and equipment monitoring are also getting a major boost from automation. Measurement sensors enable this new safety and alarm system automation wave.

Interface sensors have long been used to help automate monitoring systems in industrial machines found in manufacturing facilities. These sensors can help provide accurate data for continuous process controls of various machines on a production line or elsewhere. Deviations in that data identify issues where a machine may need to shut down or come down for maintenance abruptly. The automation functions enabled by sensors drive efficiency by notifying engineers before any disruption to production while also improving safety by avoiding malfunctions that could put workers at risk.

As the collaborative use of automation and technology has progressed, so have regulations around worker safety within industrial facilities. Robust safety systems, built with force and other sensor tech, are growing in use and application. The systems and sensor-enabled equipment are pervasive in manufacturing, whether part of cobots working on the production line or designing and testing equipment to move packages in a warehouse. Accurate measurement is quintessential to workplace safety and automation.

Included below is a list of some of the systems and machines that utilize Interface force sensors in both the testing and monitoring stages to improve workplace safety:

  • Lockout and Safety Alarms
  • Overload Protection for Heavy Equipment
  • Weighing and Scale Device Alarms
  • Industrial and Collaborative Robots (Cobots)
  • Automated Guided Vehicles (AGVs)
  • Assembly Line Equipment and Conveyor Belts
  • Crane and Lift Equipment Systems and Monitoring
  • Automated Palletizing Systems
  • Industrial Presses
  • Filling Machines
  • Testing and Inspection Equipment
  • Ergonomic Workstations and Tool Safety

The main benefits of using force sensing within these applications include the precision and accuracy of data, the ability to optimize processing using this data (especially over time), The ability to design automated safety measures based on collected data in real time, and the ability to optimize quality control in real-time. Here’s how:

Precision and Accuracy: Load cells and torque transducers provide highly accurate measurements of force and rotation, respectively. This allows for precise control of automated machinery, ensuring consistent product quality and reducing errors. Less rework and higher-quality products contribute to a safer work environment, as there’s less chance of operators needing to fix mistakes or handle malfunctioning equipment.

Process Optimization: Manufacturers can gain valuable insights into their machines’ operations by precisely measuring forces and torques. This data can be used to optimize processes, identify inefficiencies, and reduce waste. Optimized processes with smoother operation result in fewer chances of equipment malfunction and potential safety hazards.

Safety Measures: Interface sensor devices can be designed into automated machines, tools, and equipment to measure safety during use. For example, our transducers can detect overloads or excessive torque, which could lead to equipment failure and injure workers. These sensors help prevent accidents and create a safer work environment by triggering alarms or automatic shutdowns.

As noted, safety measures are required with collaborative robots in industrial facilities. Safety testing and equipment monitoring are needed to ensure humans and robots can work together. In this example, Interface suggests using four 3-axis Force Load Cells (creating one 6-axis Force Plate) installed between two metal plates at the base of the cobot. By installing a 6-axis force plate under the cobot and two ConvexBT Load Button Load Cells in the pinchers of the cobot, if a human were to knock into the cobot or have a limb stuck in the pincher, the cobot would sense the amount of force measured from the load cells and be programmed to stop immediately. This safety and automation solution protects the equipment and, most importantly, the worker.

Quality Control: Accurate measurement of forces and torques allows for real-time product quality monitoring. This enables manufacturers to identify and address any deviations from specifications early in production, reducing the risk of defective products reaching the customer. Fewer defective products mean less chance of needing rework or repairs later, keeping workers out of harm’s way.

Force sensor technology has played a key role in the evolution of modern industrial facilities as a tool to improve production while benefiting quality and powering workplace safety and health. It is one of the backbone solutions found in automation systems, and it offers highly accurate data to not only benefit real-time monitoring but also improve processes over time.

Force Makes the Circular Economy Go Around

What is a circular economy? Manufacturers and innovators are taking new approaches to reduce resource consumption and address environmental challenges. The circular economy is a model in which resources are recycled from waste into products. These resources are redesigned, reused, and remanufactured. This economic model aims to minimize waste, continuing to create a sustainable environment.

Interface’s force sensor products are used in different facilities and resource manufacturing processes within the circular economy. Our load cells and instrumentation measure and monitor forces, loads, and weight within the tools, robotics, and machinery used to optimize resources. Our sensors are also commonly used to test new products for material strength, fatigue lifecycle, quality, and function.

Interface high-accuracy test and measurement solutions are critical as organizations, and the general public become more focused on sustainability and developing innovations that improve our environmental footprint. These sensors allow companies to create better, safer, and higher-quality products that support recycling, limit the resources used, and find new ways to reuse products and materials.

Circular Economy Applications Using Interface Force Sensors

Waste Sorting and Recycling: Load cells are employed in waste sorting facilities and recycling centers to measure and monitor the weight of materials. This data helps optimize sorting processes, ensuring that recyclable materials are separated efficiently from non-recyclable waste. By accurately measuring the weight of recyclables, load cells assist in the recycling process, promoting resource recovery.

Material Recovery Facilities (MRFs): Load cells are utilized in MRFs to track the flow of materials through the recycling process. They measure the weight of materials at different stages, such as when they are dumped onto conveyor belts or compacted into bales for transport. This information is crucial for monitoring recycling rates and improving the overall efficiency of recycling operations.

Product Lifecycle Analysis: Load cells can track the weight of products and materials at various stages. This data is valuable for conducting product lifecycle assessments (LCA) to understand the environmental impact of products and identify opportunities for reusing or recycling components, thereby reducing waste and conserving resources.

Resource Optimization in Manufacturing: In manufacturing processes, load cells are used to ensure precise material usage and to control the number of raw materials used in production. This minimizes waste, helps maintain product quality, and reduces the environmental impact of manufacturing. READ: Force Measurement is Reducing Waste and Automating the Consumer Packaging Industry

Waste-to-Energy and Biogas Production: Load cells are used in waste-to-energy facilities and biogas plants to measure the weight of waste materials and organic feedstocks. This data assists in optimizing energy production while diverting waste from landfills.

Food Waste Reduction: Load cells are employed in commercial kitchens, restaurants, and production facilities to measure food waste. This information can be used to track and reduce food waste, promoting more sustainable food management practices.

Closed-Loop Supply Chains: In closed-loop supply chains, where products are designed for reuse or remanufacturing, load cells can play a role in measuring the condition and wear of components, helping determine when maintenance, refurbishment, or remanufacturing is necessary, extending the product’s life.

Optimizing Waste Sorting with Interface Load Cells

Inefficient sorting of recyclables in Material Recovery Facilities (MRFs) leads to contamination of recycled materials. This reduces the quality of the recycled product and increases costs for reprocessors. Integrate Interface miniature s-type load cells into conveyor belts at MRFs. These sensors can weigh materials in real time as they move along the conveyor.  The SSMF Fatigue Rated S-Type Load Cell measures and monitors the weight of the materials. The WTS-AM-1E Wireless Strain Bridge Transmitter Module captures and transmits the results to the customer’s computer using the WTS-BS-6 Wireless Telemetry Dongle Base Station.

The weight data is used to identify and separate materials. By setting weight thresholds, the system can trigger sorting mechanisms to divert different materials (e.g., plastics, metals, glass) into designated bins, improving the purity of the recycled streams. Real-time weight data allows for adjustments to conveyor speed and sorting mechanisms to handle surges in material flow or variations in material density. This reduces downtime and improves overall sorting efficiency. By recovering more high-quality recyclables, MRFs can divert waste from landfills, potentially reducing tipping fees.

Precise Disassembly for Remanufacturing with Interface Load Cells

Traditional methods can damage components during product disassembly for remanufacturing, reducing their reusability. This necessitates using clean materials for replacements, hindering the circular economy loop. The sensors can precisely measure the forces applied during disassembly by implementing Interface load cells into robotic disassembly lines.

Force data is used to control robotic disassembly actions. By monitoring the force applied, robots can carefully disassemble products without damaging components, allowing more parts to be reused in remanufactured products. For example, ConvexBT Load Button Load Cells can be used in the grips of the robotic arm to measure the amount of pressure being applied to the object it is lifting and moving. The DMA2 DIN Rail Mount Signal Conditioner converts the signal received from the ConvexBT Load Button Load Cells from mV/V to volts to the PLC Controller, which tells the robotic arm to stop clamping pressure when a specified amount of pressure is applied to the object.

Force data analysis can help identify areas for improvement in the disassembly process, such as adjusting robot gripper pressure or tool design. This reduces the risk of component damage and improves disassembly efficiency. By facilitating the recovery and reuse of components, Interface load cells help extend the lifespan of products and reduce reliance on clean materials.

These are just two examples of how Interface load cells can be utilized in the circular economy. By improving sorting efficiency, optimizing disassembly processes, and reducing reliance on clean materials, Interface load cells play a crucial role in creating a more sustainable future.

Interface’s load cells assist in precisely measuring forces and loads during product disassembly, refurbishment, and remanufacturing. Integrating force sensors into ways to help reduce resource consumption helps create and promote a more sustainable environment.

Strain Testing 101

Strain refers to the deformation or change in shape a material experiences due to applied stress. It’s essentially a measure of how much the material stretches, compresses, or shears (distorts) in response to a force.

Strain is quantified as the ratio of change in length to the original length, expressed as a percentage or decimal. Strain is a unitless quantity, often expressed as a percentage or decimal. On the other hand, stress refers to the internal force per unit area acting within a material due to an applied external force. It essentially quantifies the intensity of the internal forces resisting deformation.

Interface tension and compression load cells are used for strain testing across multiple industries. It is very common in general test and measurement applications.

Material scientists and engineers measure the change in a sample as it is stretched or squashed. This measurement is often used in material tests to determine durability and the ability to withstand different degrees of strain up to crushing forces.

Top Reasons to Use Strain Tests

#1 – Material Selection and Design Optimization: Strain testing helps engineers choose the most suitable material for a specific application. By understanding a material’s behavior under stress, they can select one that offers the desired strength, flexibility, and resistance to deformation. This knowledge also allows optimizing designs to ensure parts don’t overstress or underperform.

#2 – Strength and Durability Evaluation: Strain testing provides valuable data on a material’s yield strength, ultimate tensile strength, and elastic limit. This information is crucial for assessing a material’s overall strength and durability. It helps engineers predict how a material will perform under real-world loads and ensure it can withstand the forces it will encounter during its service life.

#3 – Quality Control and Consistency: Strain testing is a valuable tool for quality control in manufacturing processes. It allows manufacturers to ensure their materials and products meet specific strength and performance standards. By testing samples from each production batch, they can identify any inconsistencies or weaknesses and take corrective actions to maintain consistent product quality.

#4 – Failure Analysis and Safety Improvement: Strain testing can analyze material failures after they occur. By understanding the type and location of the strain at the point of failure, engineers can determine the root cause of the problem. This information can be used to improve material selection, design, or manufacturing processes to prevent similar failures in the future, enhancing overall product safety.

#5 – Cost Savings: While strain testing requires an initial investment, it can lead to significant cost savings in the long run. Companies can avoid costly product failures and rework by selecting the right materials, optimizing designs, and ensuring quality control. Strain testing also helps prevent over-engineering, where unnecessarily strong materials are used, leading to heavier and more expensive products.

Strain testing is a crucial technique for engineers and material scientists, offering valuable insights into a material’s behavior. It measures the deformation, or elongation, a sample experiences when stretched (tension) or compressed. This information is vital for determining a material’s durability, strength, and resistance to crushing forces. Load cells play a crucial role in this process.

Strain testing relies on load cells to convert the force applied to specimens, materials, and structures into a measurable electrical signal. During stress testing, when force is applied, the body deforms slightly, causing the resistance of the strain gages to change. This change in resistance is then converted into a voltage output, which can be precisely measured throughout the entire test and up to the object’s destruction.

By measuring strain under controlled loading conditions, engineers can determine a material’s yield strength, the point at which it permanently deforms. Strain tests can calculate the maximum stress a material can withstand before breaking and evaluate the stress level beyond which the material will not return to its original shape after unloading.

Industry Use Cases of Strain Testing

Load Cells Elevate Gantry Crane Performance

Interface provides a variety of measurement solutions for gantry crane applications. Load cells aren’t just an upgrade but a game-changer for gantry crane operations.

A gantry crane is an overhead crane with a horizontal beam supported by two legs traveling along a fixed track or wheels. They are used for lifting and moving heavy objects in various industrial settings, such as warehouses, shipyards, container yards, and construction sites.

Key features of gantry cranes include:

  • Mobility: Unlike bridge cranes, fixed to a runway system, gantry cranes can move freely within their designated area. This makes them more versatile and suitable for outdoor applications.
  • Lifting capacity: Gantry cranes can be designed to lift a wide range of weights, from a few to hundreds of tons.
  • Portability: Some gantry cranes are portable and can be easily moved from one location to another.
  • Versatility: Gantry cranes can be equipped with various attachments, such as hooks, magnets, and buckets, to handle a wide range of materials.

Benefits of Using Force Measurement Solutions with Gantry Cranes

Load cells, load pins, tension links, wireless telemetry systems, and instrumentation devices from Interface are valuable to makers and users of gantry cranes.  These vital measurement solutions offer several safe and efficient operation benefits:

Overload Prevention

  • Safety: The biggest reason is preventing crane overload. Exceeding the crane’s capacity can lead to catastrophic consequences, including equipment damage, structural failure, injuries, and even fatalities. Force measurement devices, often in the form of load cells or tension links, directly measure the weight of the lifted object, ensuring it stays within safe limits.
  • Alerts and Alarm Settings: Many devices paired with specific instruments can trigger audible or visual alarms if the load approaches the limit, giving the operator time to adjust. Some advanced systems automatically shut down the lifting operation to prevent potential overload.

Improved Efficiency and Accuracy

  • Optimal load handling: Knowing the exact weight of the load allows operators to position it precisely and efficiently. This is crucial for tasks like loading and unloading containers or placing heavy machinery with minimal risk of damage.
  • Reduced energy consumption: By lifting only the necessary weight, you optimize energy usage by avoiding unnecessary strain on the crane’s motors and systems.

Maintenance and Inspection

  • Monitoring crane health: Force measurement data can be used to track crane performance over time and identify potential issues early on. This helps with preventive maintenance and ensures the crane stays in top working condition.
  • Compliance with regulations: Many workplaces have regulations requiring the monitoring of crane loads for safety reasons. Force measurement devices provide accurate data to demonstrate compliance.

Gantry Crane Applications

Tension monitoring in cable cranes: For cranes using cables instead of hydraulics, tension links measure cable tension, safeguarding against cable stress and potential breaks.

Center of gravity determination: In complex lifts with unevenly distributed weight, measuring forces at different points helps determine the load’s center of gravity, which is crucial for safe lifting and maneuvering.

Retrofitting existing cranes for safety: Crane-safe load monitoring systems are vital to crane safety. Load pins for accurate measurement are an excellent way to modernize gantry cranes. Replacing existing load-bearing pins in the crane header block to sense the load, detect the moment of lifting a load, and monitor the cranes’ maximum safe load limit.

Weighing within winch assembly: Load pins are used to measure the weight of aluminum and steel rolls. The custom load pin was designed to fit within the winch assembly, with an anti-rotation bracket to ensure correct positioning.  We also supplied a large digit wall-mounted display to enable them to see resulting loads easily.

Safety measurement system:  If the lifting load exceeds the safe lifting load, audible or visual alarms can be triggered, or if part of a control system, that action will automatically stop the lift. Additionally, having a real-time display of the lifted load allows crane operators to lift the maximum allowable amount, improving productivity by reducing the number of lifts required to complete a task.

To improve operational efficiency and safety, a measurement system is an excellent tool that can alert the crane operator to imminent excess lifting conditions that may cause harm to operators and equipment. Overall, force measurement devices are essential for the safe, efficient, and compliant operation of gantry cranes, making them a valuable investment for any lifting operation.

What is Proof Testing and Why Does it Matter?

Proof testing determines that the failure of critical components and parts could result in costly damage to equipment and even injury in severe cases. Our measurement products are designed to be used in proof testing applications.

In proof testing applications, testing and measuring an object’s performance under extremely intense conditions, often above the specified operational use, is critical. This allows testing engineers to ensure the object can handle its rated load and go above and beyond to understand maximum performance and failure.

Interface load cells and data acquisition systems are frequently used for proof testing, which determines the strength and integrity of a test subject by applying a controlled, measured load to it. It is commonly used for general test and measurement applications for stress, fatigue, and materials testing. It is frequently used by industries such as construction, natural resources, infrastructure, heavy machinery, and manufacturing to verify the strong point and durability of objects and structures.

Top Three Reasons Why Proof Testing Matters

#1 Safety: Proof testing qualifies and quantifies the safety of equipment and structures that sustain substantial loads. Identifying weaknesses or defects is preventative, as failure can result in catastrophe. Proof testing for safety is standard for applications that include lifting equipment, rigging gear, structural supports, and components in aircraft or spacecraft.

#2 Quality: Proof testing is common during quality control to verify that equipment or materials meet the required specifications. Whether it is the equipment used in manufacturing equipment or the materials used to construct a building, proof testing is essential in defining and measuring adherence to quality standards.

#3 Reliability: Proof testing provides accurate data on the performance and trustworthiness of the tested objects. By understanding how it reacts under stress, product engineers and testing labs can validate the lifespan of a specific component or product. It is also used to define preventative maintenance requirements. It impacts production lines, product versioning, inspections, and, ultimately, the customer’s user experience.

Proof tests provide vital safety and performance measurements for equipment or structures with significant loads. It helps to prevent accidents, improve reliability, and ensure the quality and integrity of the tested item. Consult Interface Application Engineers to determine the best measurement devices for proof testing.

Proof Testing Using Load Cells

Step One: Load Cell and Set-Up

The starting point is selecting the proper measurement tool, in this case, a load cell. Consider the object’s size, expected load range, and accuracy requirements. Choose a load cell with a capacity slightly exceeding the maximum anticipated load during use.

TIP! Use Interface’s Load Cell Selection Guide

Mount the load cell and object in a stable, controlled environment. Ensure proper alignment and distribution of force on the load cell. Connect the load cell to the data acquisition system with a dedicated readout unit, computer software, or data logger, depending on your needs.

Step Two: Pre-Test and Zeroing

Most test engineers will run a pre-test at low load. This is done by applying a small force and monitoring the readings to ensure everything functions correctly and there are no extraneous signals. Zeroing the load cell to set the baseline measurement without any applied force is important. READ: Why Is Load Cell Zero Balance Important to Accuracy?

Step Three: The Test

When you start the proof test application and data recording, most technicians will increase the load gradually. As defined in a test plan, follow a preset loading schedule, typically in increments, until reaching the desired test load. This could be a static load held for a specific time or a cyclic load simulating real-world conditions. Next, using your load cell measurement instrumentation, monitor the load cell readings, object behavior, and any potential visual deformations throughout the test.

Step Four: Analysis

The proof testing provides data that can be used to analyze the load-displacement curve, identifying any deviations from expected behavior, excessive deflections, or potential failure points. Based on the data, determine if the object met the strength and performance requirements or exhibited any unacceptable flaws. This is why a high-performance, accurate load cell matters in proof testing. It determines the quality of your analysis. As with any testing, it is valuable to maintain records of the test procedure, data, and conclusions for future reference or further analysis. This step is crucial for regulatory and product liability requirements.

The specific requirements and procedures for proof testing will vary depending on the product, equipment, structure, industry standards, and regulations.

Proof Testing Example

The most straightforward solution, where it is necessary to measure the load in a tension cable subject to safety considerations, is to enclose the load cell in a compression cage, which converts tension into compression. The compression cell is trapped between the two plates. Thus, the load cell’s only overload failure mode is in compression, allowing a motion of 0.001″ to 0.010″ before the load cell becomes solid. Even if the load cell is destroyed, the compression cage cannot drop the load unless it fails. Therefore, the cage can be proof-tested with a dummy load cell or an overload-protected cell, and the risk of injury to personnel is avoided.

TIP! This example is detailed in our Interface Load Cell Field Guide. Get your copy here.

The nature of proof testing applications requires a diverse line of performance measurement tools.

Our depth of force measurement expertise and experience enable us to innovate, engineer, and produce the world’s most accurate, reliable, and quality sensor technology for manufacturers worldwide.  This can be seen through some specific application examples in which Interface solutions have been involved. We have included a few of these examples below.

robotic grinder containing 6A40 6-Axis Load Cell and BX8-HD44 BlueDAQ Series Data Acquisition SystemRobotic Grinding and Polishing During Production

Robotic grinding and polishing are commonly used in manufacturing. Robots or cobots are programmed to grind and polish on varied materials and surfaces. A force measurement system must be implemented to monitor and control the force exerted on the grinding workpiece. Interface’s Model 6A40A 6-Axis Load Cell can be installed between the flange and the grinding tool. When connected to the BX8-HD44 Data Acquisition, the customer can receive force and torque measurements when connected to their control system using BlueDAQ software. The 6A40-6 Axis Load Cell measures all forces and torques (Fx, Fʏ, Fz, Mx, Mʏ, Mz), and our BXB-HD44 Data Acquisition logs, displays and graphs these measurements while sending scaled analog output signals for these axes to the robot’s control system. Manufacturing: Robotic Grinding and Polishing application.

Manufacturing Feed Roller System

A customer has a feed roller system that monitors the forces of both ends of the rollers to maintain a constant straight feed. They preferred a wireless system. Interface suggested installing two PBLC Pillow Block Load Cells at both ends of the bottom roller to measure the applied forces. The forces were measured when connected to the WTS-AM-1E Wireless Strain Bridge Transmitter Module. The data was then transmitted wirelessly to the WTS-BS-6 Wireless Telemetry Dongle Base Station and the WTS-BS-1-HA Wireless Handheld Display for multiple transmitters, where data was displayed, graphed, and logged on the customer’s PC or laptop. The PBLC Pillow Block Load Cells installed at the bottom roller were able to measure and monitor the forces to maintain the straight feed by the rollers. Manufacturing: Feed Roller System app note.

Press Load Monitoring for Material Testing

Press forming is a method to deform different materials. For instance, materials such as steel can be bent, stretched, or formed into shapes. A force measurement solution is required to monitor the forces the press-forming machine applies. This ensures quality control and traceability during the production process. Interface recommends installing the 1000 High Capacity Fatigue-Rated LowProfile™ Load Cell for large press forming machines. When the material is placed under the punch plate to form a shape, the force applied is measured by the Interface 1000 Series Load Cell. The captured force results are sent to the INF-USB3 Universal Serial Bus Single Channel PC Interface Module, where results can be graphed and logged on the customer’s PC using the provided software. Interface’s force measurement products and instrumentation accurately monitored and logged the force results of the press force machine, ensuring zero-error production performance.

Interface began designing and manufacturing load cells and other force measurement equipment in 1968. These precision load cells are commonly found in factories worldwide in testing equipment, scales, machines, and production line devices. Load cells help bring life to older machines with accurate measurements while in use, ultimately improving maintenance and worker safety in manufacturing.

Our force measurement products are versatile and valuable tools for manufacturers. Our sensor solutions improve the quality, safety, and efficiency of products and the equipment and tools used to make them.
