Force Sensors Advance Industrial Automation

Industrial automation heavily relies upon the use of sensor technologies to advance production and manufacturing. In the next phase of the industrial revolution, also referred to as Industry 4.0, gains in operational efficiencies are often rooted in innovative tools, robotics, and equipment renovations. These types of enhancements require use of interconnectivity, automation, machine learning, and real-time data. Interface is playing a significant role in enabling these advancements with smart force and torque measurement solutions.

Randy Franks at Sensor Tips poses the following question in a recent article: How can force sensing be integrated for Industry 4.0 upgrades?

“Upgrading facilities to industry 4.0 standards is one of the most significant trends in the manufacturing industry today. To do this, original equipment manufacturers (OEMs) are pushing hard to renovate their facilities with connected, automated devices and machines to create greater efficiency and cost savings. Smarter devices can ease the transition.”

He continues in his post to note, “For Industry 4.0, force measurement solutions providers are integrating actuators that move and control a mechanism or system with load cells to create fully automated force test systems.”

Illustrating how this work, Randy writes about manufacturers of mobile devices using force measurement testing automation to pressure test touch screens with the new Interface ConvexBT miniature-sized load button load cells

Interface Force Measurement Solutions Featured in Quality Magazine

Choosing a force measurement device and getting the most out of it is a tricky process, even for the most seasoned engineers. So, when Quality Magazine asked our Chief Engineer and VP of Quality, Ken Vining, to share his knowledge of force measurement, he decided to put together a guide on what to look for in force measurement equipment and how to use and maintain your equipment properly.

In his Quality Magazine article titled, “Selecting and Using a Force Measurement Device: Everything you need to know,” Vining explains the contributing factors to force measurement device quality and accuracy, as well as a few tips and tricks to make sure you’re getting the best possible accuracy and longevity out of your device.

Included below is a brief introduction from article:

Force measurement devices like load cells, torque transducers and data acquisition devices are used across industries to design and test hardware. They’re a key factor in the product development process because the force, torque and weight data they collect helps to ensure products are accurately constructed, work as intended, are safe for use, and can withstand the test of time. In highly regulated and complex industries like medical and defense, this data becomes even more important because any miscalculation in the design of a product can put lives at risk.

The first thing to understand is every project requiring a load cell or torque transducer has different variables affecting accuracy and quality. And for every situation in product development and testing, there is a load cell to fit your precise need. Therefore, the most important step in ensuring accurate and high-quality data is speaking to a force measurement expert about the details of a project.

Robotics in Play with New Animated Application Using ConvexBT

Numerous factors are driving the industry 4.0 revolution. From big data to IoT technology, industrial facilities and manufacturing plants are looking at new ways to automate their process and create a more efficient and cost-effective environment. One of the most important technology advancements in this mix is robotics.

Robotic equipment is a common industry 4.0 innovation used to create an autonomous or semi-autonomous machine capable of carrying out a variety of repetitive tasks that used to take up the time of skilled labor. Some of the tasks or processes that robotics enhance include stock management and logistics, manufacturing automation, janitorial duties and, there are even robotic applications called co-bots that assist human workers when ultra-high precision is needed.

To facilitate the demand for robotics, a variety of sensor and measurement components are necessary to ensure the highest quality and reliability of these application. Many tasks carried out by robotic applications are ultra-precise and require more accuracy than what a human hand or eye can handle.

Sensor technologies embedded in the actual robotics instrument must also be used to constantly calibrate or monitor the robotics. If robotics is used on an automated manufacturing line, any issues with the robotics can disrupt and compromise the entire process. Therefore, robotics manufacturers utilize Interface solutions when they need quality sensors that can monitor the precision of the robotics and ensure that their accuracy and reliability is maintained.

Interface develops high-quality test and measurement solutions designed for hardware testing of all kind. For robotics, our products are frequently used as a component within an OEM device. We understand the premium accuracy and reliability necessary to help develop robotics solutions and have provided both off-the-shelf and custom force measurement solutions designed to meet a variety of applications. We recently created an animated application note on an industrial automation robotic arm using our new light weight, light touch load button load cell, the ConvexBT.

The ConvexBT is designed for testing and also for full integration into the robotic element to measure the force pressure during use.  ConvexBT is available in multiple capacities, including our latest release of the 500lb and 1Klb models.

NEW! Interface Robotic Arm Application Note

A customer came to Interface with a robotic arm product that would be used to lift and move delicate objects, such as a glass bottle, in an automated environment. The goal in using Interface was to find a force measurement product that could ensure the robotic arm did not damage the products it was moving by applying too much force. The main component that Interface products would be applied to is the robotic arms’ clamp. The objective was monitoring the grabbing pressure of the clamp and ensure that the device would stop applying pressure when the necessary force was used to pick up the object without doing damage.

Using its new line of Load Button Load Cells, ConvexBT, and a DMA2 DIN Rail Mount Signal Conditioner, Interface provided a solution that would produce an electric signal on the clamping process that tells a controller to have the device stop applying pressure. Two ConvexBT products were connected underneath the rubber pads on both sides of the robotic arm clamping device. When the clamps made contact and applied pressure, the DMA2 Signal Conditioner converted the signal from the ConvexBT from MV/V to volts to a PLC controller. This signal tells the controller when to have the robotic arm stop applying clamping force.

Ultimately, the two ConvexBT Load Button Load Cells were able to accurately measure the amount of pressure applied to the object the robotic arm was lifting and moving without causing any harm or damage to the object.

This is just one of many examples of force measurement products being used in the robotics and automation industry. As the demand for robotics grows and a wider variety of applications are introduced, Interface will continue to engineer the best solutions to help customers reach the age of Industry 4.0.

Load Cell Test Protocols and Calibrations

In the Interface Load Cell Field Guide, our engineers and product design experts detail important troubleshooting tips and best practices to help test and measurement professionals understand the intricacies of load cells and applications for force measurement devices. In this post, our team has outlined some helpful advice for testing protocols, error sourcing and calibrations.

The first step in creating test protocols and calibration use cases is to define the mode you are testing. Load cells are routinely conditioned in either tension or compression mode and then calibrated. If a calibration in the opposite mode is also required, the cell is first conditioned in that mode prior to the second calibration. The calibration data reflects the operation of the cell only when it is conditioned in the mode in question.

For this reason, it is important that the test protocol, which is the sequence of the load applications, must be planned before any determination of possible error sources can begin. In most instances, a specification of acceptance must be devised to ensure that the requirements of the load cell user are met.

Typical error sources in force test and measurement are usually identified as being related to:

  • Lack of protocol
  • Replication of actual use case
  • Conditioning
  • Alignment
  • Adapters
  • Cables
  • Instrumentation
  • Threads and loading
  • Temperature
  • Excitation voltage
  • Bolting
  • Materials

In very stringent applications, users generally can correct test data for nonlinearity of the load cell, removing a substantial amount of the total error.  If this can’t be done, nonlinearity will be part of the error budget.

An error budget is the maximum amount of time that a technical system can fail without service level consequences. In force test and measurement, it is sometimes referred to as uncertainty budget.

Nonlinearity is the algebraic difference between output at a specific load and the corresponding point on the straight line drawn between minimum load and maximum load.

Nonrepeatability is essentially a function of the resolution and stability of the signal conditioning electronics.  Load cells typically have nonrepeatability that is better than the load frames, fixtures and electronics used to measure it.

Nonrepeatabillty is the maximum difference between output readings for repeating loading under identical loading and environmental conditions.

The remaining source of error, hysteresis, is highly dependent on the load sequence test protocol.  It is possible to optimize the test protocol in most cases, to minimize the introduction of unwanted hysteresis into the measurements.

Hysteresis is the algebraic differences between output at a given load descending from maximum load and output at the same load ascending from minimum load.

There are cases when users are constrained, either by requirement or product specification, to operate a load cell in an undefined way that will result in unknown hysteresis effects. In such instances, the user will have to accept the worst-case hysteresis as an operating specification.

Some load cells must be operated in both tension and compression mode during their normal use cycle, without the ability to recondition the cell before changing modes. This results in a condition called toggle, a non-return to zero after looping through both modes. The magnitude of toggle is a broad range. There are several solutions to the toggle problem, including using a higher capacity load cell so that it can operate over a smaller range of its capacity, use a cell made from a lower toggle material or require a tighter specification.

Understanding Uncertainty in Load Cell Calibration

In force measurement testing, accuracy is the most critical factor in ensuring the data you collect can help to identify challenges, failures and opportunities in the product design and development cycle. Here at Interface, we have mastered the art of load cell accuracy by employing a vertically integrated manufacturing process that allows us to control the development of our products most critical components.

Even the most high-end manufactured load cells and finely tuned components endure accuracy degradation over continued use. Therefore, we have also invested in equipment and talent with deep expertise in load cell recalibration, as well as offering gold and platinum standard calibration systems to customers. Recalibration is recommended on an annual basis, or of course, whenever our customers feel they need to confirm they are getting the right data out of their load cells.

One of the key factors of calibration and recalibration is understanding how to estimate practical uncertainty in load cell calibration. Measurement uncertainty is defined as an estimate of the range of measured values within which the true value lies or, alternatively, the degree of doubt about a measured value. In every application, there will be an uncertainty requirement on the force measurement. The equipment used to make the measurement must be traceable to a realization of the SI unit of force (the newton) within this required uncertainty.

Each application is different in terms of its uncertainty requirement. For instance, an application testing force in the aerospace and defense or medical sector will include a much more stringent uncertainty requirement than something like a commercial scale used to measure someone’s weight or food. It is critical to understand the uncertainty requirement on the application to ensure the force measurement device used is calibrated to handle the project.

How does one go about estimating uncertainty in load cell calibration? The first thing to understand is the GUM, a guide to the expression of uncertainty in measurement. This guide establishes general rules for evaluating and expressing uncertainty in measurement that are intended to be applicable to a broad spectrum of measurements.

Next, we have included a list of different considerations, as we measure uncertainty here at Interface. These factors will help guide you as you determine uncertainty for yourself. This list includes:

  1. Determine what parameter is to be measured and the units of measure.
  2. Identify the components of the calibration process and the accompanying sources of error.
  3. Write an expression for the uncertainty of each source of error.
  4. Determine the probability distribution for each source of error.
  5. Calculate a standard uncertainty for each source of error for the range or value of interest.
  6. Construct an uncertainty budget that lists all the components and their standard uncertainty calculations
  7. Combine the standard uncertainty calculations and apply a coverage factor to obtain the final expanded uncertainty.

It is also important to consider the different methods of load cell calibration. There are three different methods, and each has an approximate feasible expanded uncertainty. The different calibration methods include:

  • Direct dead weight – this method is the best for accuracy at 0.005% uncertainty, but it is slow, and the equipment is space inefficient.
  • Leveraged dead weight – middle of the road for accuracy at 0.01% uncertainty, and slow and space inefficient.
  • Hydraulic force generation comparison – this method has reasonable accuracy at 0.04% uncertainty and is also the fastest and most space-efficient option.

The final point is the sources of error in calibration. Error is defined as the difference between the measured value and the true value. There is a long list of different factors that can cause error and increase uncertainty. These factors may include drift, creep, misalignment, or environmental factors such as temperature. To compensate for this, it is important to understand the various formulas that can be used to find the true value based on the given measurement and the various factors for error.

The Five Critical Factors of Load Cell Quality

Accurate data and high-quality test and measurement programs have many contributing factors. None are more important than the devices and equipment used on the test line. At Interface, we understand this better than anyone else.

Quality is why our force measurement products are used and known across multiple, highly regulated, and complex industries for providing the most reliable and accurate data anywhere. It is also why Interface is recognized as the preeminent leader in load cell quality.

How do we reach this high standard that we continue to hit with every product that leaves our facility? It is our overriding commitment to quality and consistency. The most important aspect of this is the fact that Interface controls the entire manufacturing process of our load cells. Many providers outsource certain components like that strain gages. We build the strain gages, the load cells, integrate the strain gages into the load cells and we do our own test, calibration, and quality inspection on each device.

Through our development process, which has been created and perfected over 52 years, we have learned what makes a great load cell. To start, Interface Chief Engineer Ken Vining outlines the top factors in load cell quality.

Five Most Critical Factors of Load Cell Quality

#1 Repeatability

Repeatability is first on the list and it is what our customers consider the most important aspect of buying an Interface load cell. Anyone can develop a load cell that is accurate for the first 10 to 15 measurements, but as environmental factors and stress are inflicted upon the load cell it needs to last. Due to our experience in this industry, we understand how certain temperatures, loads and other factors can diminish the accuracy of a load cell. This is one of the reasons we work so closely with our customers. Every application is different, and if we understand the application, we can deliver a custom load cell that withstands the various stressors over time without providing diminishing returns. This ensures that our customers receive the same, high-quality data after 10 years of use that they received on day one.

#2 Longevity

Like repeatable data accuracy over time, the load cell also needs to feature a high-quality and ruggedized build to last physically. Constant application of weight, pressure or torque can diminish the build quality and strength of a load cell if it does not meet the material requirements of the application. This can also reduce accuracy and lead to higher costs if customers must replace their load cells regularly. Interface has worked across a wide variety of industries and we understand the materials necessary for nearly any environment. With proper use, build quality and routine maintenance, load cells should last a very long time. In fact, Interface still has load cells in use in the field from when we started building quality product more than five decades ago.

#3 Accuracy

Data accuracy is affected by a litany of factors in load cells. In fact, we wrote an entire white paper on this very topic called, “Contributing Factors to Load Cell Accuracy.” Once again, the application of the load cell is what determines the conditions that affect accuracy. These conditions include creep, side and eccentric load, temperature, humidity, the mounting process and more. Interface can customize each of our load cells to ensure these conditions are accounted for to maintain premium accuracy.

#4 Sensitivity to Off-Axis Loads

A typical load cell is designed to measure load in one direction. However, nearly any project using force measurement test processes is going to introduce an off-axis load. If the load cell is not designed to adjust for this and compensate for what is called moment, the data output will be skewed. This is another reason that customers need to be extremely specific when discussing the application of the load cell. There are several ways to compensate for moment; however, most of these adjustments are physical and occur in the design and manufacturing process. With a correctly calibrated and designed load cell, off-axis loads will be eliminated and will not affect the accuracy of the data.

Special Note: Our recent release of the new ConvexBT product, the first to market miniature load button load cell that is designed to solve for off-axis (eccentric) loading. Read more here.

#5 Access to Prominent Force Measurement Experts

Every factor of quality listed above is realized and accomplished through a close and transparent relationship between customer and force measurement provider. Every application dictates a different force measurement solution. When we understand the application, we can select the right type of load cell or customize an off the shelf load cell to meet the quality and accuracy needs necessary for any project. This is why a customer’s access to a force measurement expert is an integral part of load cell quality.

Every force test and measurement project can create a different challenge and developing an accurate and reliable load cell to meet those challenges can be tough. Therefore, Interface considers these five factors, and hundreds more, for every product we engineer and build. This is our unwavering commitment to quality and customer satisfaction.

Driving Force in Automotive Applications

Among the most highly regulated industries in the world, automotive is up there with the likes of medical and defense. Every component and system needs to be thoroughly tested and deliberately analyzed to ensure that the final product is safe for the driver, other vehicles and pedestrians. Any mistakes or failures can cause catastrophic damage and put lives at risk.

There are hundreds of thousands of different tests that car parts and software go through before they are approved for the road. Among them is force measurement testing. Force and torque tests are integral to the structural and mechanical design and build of the car. Gathering data on the build quality and safety of materials and components found within cars, trucks and more is done through a wide variety of different force measurement testing.

Interface has been a partner to the automotive industry for more than 50 years, from the major OEMs to smaller parts manufacturers and test labs. We build force and torque sensors and acquisition devices designed to provide automotive engineers and manufacturers with high-quality data to monitor and confirm the design and in-action processes of a wide variety of vehicles.

Force testing applications for the automotive industry involve everything from structural, engine, brake, seat belt and suspension tests, all the way down to individual lug nut torque testing.

Recently, Interface has also been supplying solutions to those in the growing electrical vehicle (EV) market. EV cars and other motor vehicles present a wide variety of unique challenges for engine torque and battery technology testing.

As an example of some of the products we offer to the industry, we are highlighting Interface expertise in different automotive applications. This will include specific examples of work we’ve done for our customers recently or in the past.

BRAKE PEDAL TESTING

One of the largest areas of automotive test and measurement we are involved in is brake pedal testing. Our customers need to ensure that applying certain amounts of force to the brake will slow and stop the vehicle as intended.

In this application note, Interface supplied our customer with a BPL-300-C Brake Pedal Load Cell, which was installed on the brake pedal. As the user depressed the brake pedal, force data was transmitted by our BTS-AM-1 Bluetooth Low Energy (BLE) Strain Bridge Transmitter Module to the BTS Toolkit Mobile App and displayed on a mobile device. This allowed our customer to view and graph the data in real-time.

Read the application note for Brake Pedal Testing here.

EV BATTERY TESTING

In the EV market, one of the most integral pieces of technology is the battery used to run every piece of hardware and software in the car. One of the critical tests that’s performed on EV batteries in compression testing. As an EV battery is charged and stores more electrons, it swells. If the packaging that houses the batteries is not intelligently designed to compensate for this swelling, you could have a major problem.

For this challenge, Interface can supply the popular WMC Miniature Load Cell. The load cell will measure compression force as a battery goes through charge cycles on a test stand to determine the force given off as the battery swells. This allows our customers to design the proper packaging for the batteries.

Read more about Interface’s role in the The Future of Automotive is Electric.

SUSPENSION TESTING

A personal favorite of the Interface team is a suspension test we performed on a race car. As you can imagine, race car components need to be finely tuned for optimal performance. The suspension is one of the most significant factors in the tuning process.

Using an Interface Model 1200 Standard Load Cell, we were able to measure simulated motions of a racetrack including bumps, banks and other track conditions. This allowed the customer to gather highly accurate (0.04%) measurements of loads applied to individual suspension points. This type of suspension testing technology can also be performed on a regular commercial automobile, but the race car example is much more fun!

View the race car suspension testing application here.

MOTOR TESTING

In this motor test stand application, it was used in the quality control lab of a major automotive manufacturing customer that needed to test, record and audit the torque produced by a new motor design under start load.

Interface supplied a Model AxialTQ Rotary Torque Transducer that connected between the motor and the differential, on the drive shaft, which could measure and record these torque values. Based on the data collected using the AxialTQ, AxialTQ Output Module, and customer laptop, the test engineer was able to make recommendations to optimize the amount of torque created by the new motor design.

You can read more about the AxialTQ in this post.  

The wide variety of applications for automotive force testing that Interface has been involved in is significant. We have many published application notes beyond those highlighted, including Seat Testing, Engine Head Bolt Tightening and one for an Engine Dynamometer (dyno for short) use case. The examples listed above just scratch the surface.

Interface is a preferred partner to the automotive industry.  To review some of the automotive application notes we have published, please check out our website at /solutions/automotive-vehicle/.

Test Stand Applications for Force and Torque

In the world of test and measurement, test stands are essential equipment for manufacturers and testing engineers. The test stand provides a host of different testing products in a single “cabinet-like” structure. These systems have been used for a long time to gather data on various functions of products during the product test phase.

Test stands works like a mobile test lab, hosted by a frame and containing one or more force or torque sensor components, software, and data acquisition instrumentation and accessories. Force stands are typically motorized or manual.  Motorized test stands, also known as mechanical or electrical, have the advantages of controlling performance by applying modes such as speed, cycles, and time into the testing procedure. The more advanced testing stands are frequently used for repetitive high-performance testing requirements, validating accuracy and quality. Manual test stands are used for simple testing protocols and frequently used in education programs.

There are a wide variety of testing devices and sensor products that are used as part of the entire test process. As parts roll off the production line, the test stand will sit at the end of the line where the test engineer can immediately load the product into the test rig. Test stands help to streamline the test process by providing all available test functions in a single, mobile application.

Interface is a supplier of choice for precision components of various capacities and dimensions for test stand configurations requiring precision and accuracy in performance. Interface load cells, torque transducers, and instrumentation equipment are commonly used in numerous product test applications by engineers, metrologists, testing professionals and product designers around the world.

Included below are a few examples of specific test applications and the Interface components used in the different style testing stands.

Linear Test Stand

In this example, an Interface customer wanted to add a crush test to their test stand to measure the force it took to deform a piece of material. Interface provided an Model 1210 Load Cell with an internal amplification of 0-10VDC output.

The load cell was installed into the load string of the customer’s load frame, and the scaled analog output from the load cell was connected to the customer’s test stand instrumentation. When the force levels reached the crushing point, the customer’s software was able to read the output of the amplified load cell and record the value.

See the application note for the Linear Test Stand here.

Motor Test Stand

In the quality control lab at a major automotive manufacturing company, a test engineer needed to test, record, and audit the torque produced by a new motor design under start load. Interface supplied the new AxialTQ® Rotary Torque Transducer that connected between the motor and the differential, on the drive shaft, that could measure and record these torque values.

Based on the data collected using the AxialTQ transducer, along with the AxialTQ Output Module, and a laptop, the test engineer was able to make recommendations to optimize the amount of torque created by the new motor design.

See the application note for the Motor Test Stand here.

Verification Test Stand

In this application, a customer needed a test stand application to verify that its load cell was in good, working order. Interface helped to create a solution that used a load cell to verify the customer’s load cell. The solution involved the customer’s supplied verification load frame and an Interface Model 1210 Precision LowProfile® Load Cell connected with a Model SI-USB 2-Channel PC Interface Module.

The customer was able to install their load cell and Model 1210 Precision LowProfile Load cell into the verification load frame. Applied forces were displayed and recorded by Model SI-USB PC Interface Module for review and record keeping on customer’s computer. This allows the customer to have a proven load cell verification test stand at their disposal to ensure its test load cell is always in working order.

See the application note for the Verification Test Stand here.

These are just a few examples of the different types of test stands that Interface can provide off-the-shelf or custom force measurement solution components.
