New Interface Multi-Axis Sensor Selection Guide

/0 Comments/in /by

Interface multi-axis sensors have multiple benefits for test and measurement applications. Beyond providing more data, they consolidate measurement signals and conserve test space.

Interface multi-axis sensors are like other force and torque sensors with strain gage bridges bonded to machined flexures. Each bridge typically defines a measurement axis. Interface offers multiple configurations for 2, 3, or 6-axis options: axial and torque, axial and shear, axial and moment, and all six degrees.

Most force and torque sensors are bidirectional, tension, and compression. Many sensors can be dual or triple-bridge for dedicated or redundant signals. These types of load cells output the same signal and direction of measurement.

Uniquely, multi-axis sensors have additional bridges to provide output signals for varying axes or types of mechanical loading. Interface multi-axis sensors are designed to provide a complete picture of the test article by quantifying reaction loads through the test article on the “non-measure” side.

These specialized load cells are used in various applications across industries, including aerospace, robotics, automotive, and medical device research. These sensors are specifically designed for applications requiring measuring moment and axial loads to determine the center of gravity or misalignment. They are used for tests requiring simultaneous force and torque monitoring, such as bearing test and material test machines, rheometry test machines for rubber testing, or continuous stress testing of equipment like pumps and master key systems. The multi-axis sensor offers better fatigue testing through setup and load verification.

Below is a demonstration using Interface’s 6-Axis Sensor with our BX8 to measure the precise movements of a robotic hand.

Small in Dimension and Precise in Measurement

/0 Comments/in /by

The world of force measurement is vast. Interface products are used across industries and in a wide range of applications. From the measurement of minute forces in catheter stint testing to jumbo load cells for massive structural testing of rockets, Interface load cells provide highly accurate measurement no matter the size of the load cell.

One of the many benefits of Interface products is the extensive range of measurement capacities and dimensions we offer, including our Mini Load Cells used for small and precise measurements. Interface Mini™ load cells are ideal for light touch, weight, or limited space test and measurement applications. The Mini Load Cells provide remarkably accurate measurements like our LowProfile load cells. With capacities available as low as 0.11 lbf / 0.5 N and as high as 100 kN, there are various miniature load cells for testing and options for custom OEM solutions.

TIP: Explore your options with our Mini Load Cell Selection Guide

Typical applications for measuring tiny, accurate forces are within the medical, manufacturing, robotics, and consumer product industries.

Medical device manufacturers are working to provide handheld point-of-care devices for patients. Additionally, medical devices used within the human body must provide extremely delicate forces to achieve their intended purpose without harming the patient.

Take something that seems relatively simple, like a vascular clamp. These types of delicate instruments are used on heart valves. If they provide too little force, they cannot do their job. However, providing too much force could severely harm the patient. Medical device manufacturers of these surgical tools use miniature load cells to measure the clamping force to ensure precise accuracy to toe the line between too much and too little force, which is a very precise number.

In the pharmaceutical industry, very small load cells are crucial for accurately measuring the force applied to the pills (tablets) during the press marking phase and other manufacturing processes to ensure consistent dosage and tablet integrity.

With consumer products, precision force measurement is critical to various manufacturing processes and real-time monitoring. A load button load cell is the right size for testing the durability of a smart device by applying a force to the screen and measuring the amount of force the screen can withstand before cracking or breaking. Read: Touchscreen Force Testing App Note

A miniature load cell can measure the force required to open a food package. This information can be used to ensure that the packaging is easy for consumers to open and secure enough to protect the food from damage. In food processing, load cells measure the force applied to food during mixing, blending, and other processes to ensure consistent product quality and prevent damage to the food itself. For instance, load cells can monitor the force applied to a dough mixer to ensure the dough is correctly mixed without becoming overworked or tough.

SMALL AND PRECISE MEASUREMENT APPLICATIONS

SPECIMEN RESEARCH

In the medical industry, medical experts need the best equipment to research multiple specimens. In this case, a medical researcher needs to monitor the load force of their linear actuator that uses a needle to collect material from the desired specimen. Interface’s SuperSC S-Type Miniature Load Cell can easily be installed into the linear test stand. A needle with a gripper on the end is installed on the lower end of the SuperSC. As the needle is pushed to collect specimen material, the load feedback is captured using the 9330 Battery Powered High-Speed Data Logging Indicator through an SD card or another laptop. Read: Specimen Research App Note

AIRBAG CONNECTOR TESTING

Testing airbag connectors functionality is needed to ensure perfect deployment in case of a car crash. Eight to twelve connectors are installed in each vehicle, and tests must be made to clarify whether the connectors are working effectively. These connectors usually work when latched, but that does not ensure the electrical properties are performing. The amount of force needs to be tested to see when an electrical current is connected. Interface’s solution is to attach the WMC Sealed Stainless Steel Miniature Load Cell to the actuator of the test rig. The airbag connector is placed at the test rig’s bottom. Forces are applied and measured using the 9330 High-Speed Data Logger as the connector is pushed down to latch together. When connected to a computer, results can be logged, downloaded, and reviewed.

COBOT MONITORING SYSTEM

Collaborative robots, or cobots, are offering more manufacturing operations in the industrial packaging industry. Protective cages or fences are no longer needed for safety purposes, but safety testing is still required to ensure humans and robots can work together. Four 3-axis Force Load Cells (creating one 6-axis Force Plate) are installed between two metal plates at the base of the cobot. Interface suggests 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 any object stuck in the pincher, the cobot would sense the force measured from the load cells and be programmed to stop immediately.

Interface can serve a wide range of test and measurement applications from millions of pounds force to the most minute. If you want sensors with small, more precise measurement capabilities, please check out our miniature load cell selection guide.

Center of Gravity Testing in Robotics Demands Precision Load Cells

/0 Comments/in , /by

As the use of robotics expands across industries and the types of robotic motions grow in complexity, advanced testing using quality measurement solutions is essential. Contact momentum and gross measurements of indicators are not enough for sophisticated robotics. With the requirements for robots and cobots to have fluid and inertial movement capabilities, control and feedback demand maximized feedback and resolution.

Related to the testing of inertia, load shifting, and interaction, is defining the center of gravity for robots’ actions and applications. The center of gravity (CoG) of a robotic system is a critical factor in its stability and performance.

The CoG is the point at which the entire weight of the system is evenly distributed. If the CoG is not properly located, the system may be unstable and prone to tipping over, which could damage the robot.

For any robotic application that deploys advanced mobility features, the center of gravity can affect the way the system moves. It can also impact the exactness of its movements. Thus, it is essential to use measurement solutions that are highly precise. See: Advancements in Robotics and Cobots Using Interface Sensors.

Why Robotic Engineers Care About CoG Testing

  • Stability: The CoG is a major factor in determining the stability of a robot. If the CoG is not properly located, the robot may be unstable and prone to tipping over. This can be a safety hazard, and it can also damage the robot. It is an expensive mistake to not have stability proven before moving forward with the design.
  • Performance: The CoG can also affect the performance of a robot. If the CoG is located too high, the robot may be less maneuverable. If the CoG is located too low, the robot may be less stable. By optimizing the CoG, robotic engineers can improve the performance of the robot and use for actions that rely on exact movement.
  • Safety: In some industries, such as manufacturing, medical and aerospace, there are safety regulations that require robots to have a certain CoG. For example, in the automotive industry, robots that are used to weld cars must have a CoG that is below a certain point. By testing the CoG of their robots, robotic engineers can ensure that they are meeting safety regulations.

There are different methods for determining the CoG of a robotic system. One common method is to use strain gage load cells. Not all load cells are designed for precision measurement. Interface specializes in precision. Center of gravity testing demands strict measurement. For example, Interface compression load cells are often used in center of gravity testing for robotics because they are very accurate and can measure remarkably small forces.

Interface load cells measure force, and they can be used to determine the weight of a system at different points. By measuring the weight of a system at different points, it is possible to calculate the location of the CoG.

Interface load cells used for center of gravity testing are typically in our miniature load cell line, due to the size of the installation and testing environment. Miniature load cells are easily embedded into robotics, as well as can be used for continuous monitoring.

Surgical Robotic Haptic Force and CoG

Robots used for surgery often utilize haptic force feedback for ensuring that the surgeon does not apply too much force, creating harm or greater impact on the patient. Haptic is the use of force, vibration, or other tactile stimuli to create the sensation of touch. In the context of invasive surgery, haptic force feedback from robotics is used to provide the surgeon with feedback about the forces they are applying to the patient’s tissue. CoG testing can help to prevent the robotic arm from tipping over during surgery.

CoG testing is important for haptic force feedback in invasive surgery because it ensures that the robotic arm is stable and does not tip over during surgery. The CoG is the point at which the entire weight of the robotic arm is evenly distributed. If the CoG is not properly located, the robotic arm may be unstable and prone to tipping over. This can be a safety hazard for the surgeon and the patient.

CoG testing is also used to optimize the design of the robotic arm for haptic force feedback. CoG testing using precision load cells can verify the performance of the robotic arm in haptic force feedback applications. After the robotic arm has been designed and optimized, CoG can ensure that the robotic arm is able to provide the surgeon with the feedback they need to perform surgery safely and accurately.

Robotic Center of Gravity on Production Line

A company is developing a new robotic arm that will be used to simulate human behavior on a manufacturing product line. The robotic arm will be used to pick and place products, and it is important that the arm is stable and does not tip over. To ensure the stability of the robotic arm, the company needs to determine the CoG of the arm. The load cell is placed on the arm, and the arm will be moved through a range of motions. The data from the load cell will be used to calculate the CoG of the arm.

CoG Testing and Multi-Axis Sensors

Multi-axis load cells are growing in use for robotics testing to provide data across 2, 3 or 6 axes at any given time. These high functioning sensors are ideal for robotic tests where there are simulations of human behaviors. This is detailed in Using Multi-Axis Sensors to Bring Robotics to Life.

To perform CoG testing using precision load cells, a robotic system can be placed on a platform that is supported by the load cells. We call these force plates. The load cells measure the weight of the system at different points, and the data is then used to calculate the location of the CoG. Visit our 6-Axis Force Plate Robotic Arm application note to learn more about force plates and multi-axis sensors.


Benefits Of Using Precision Load Cells for CoG Testing:

  • Interface precision load cells provide advanced sensors functional beyond contact and simple indicator measurement, to maximize robotic feedback and optimize performance.
  • Interface precision load cells can provide accurate measurements of the weight of a robotic system at different points.
  • Interface precision load cells are repeatable and dependable, which means that the results of CoG testing are consistent when testing robots and cobots.
  • Interface precision load cells are easy to use, which makes them a practical option for CoG testing and integration into the actual robot.

There are several benefits to using an Interface Mini Load Cells, like our ConvexBT Load Button Load Cell or MBI Overload Protected Miniature Beam Load Cell for high accuracy CoG testing.

First, the miniature load cell is small and lightweight, which makes it easy to attach to the robotic arm. Second, the load cell is designed for precision measurement, which ensures that the CoG of the arm is accurately determined. Third, the quality of Interface precision load cells provides repeatable and dependable measurement, which means that the results of CoG testing are consistent.

Using a miniature load cell of high accuracy is a valuable way to test the CoG of a robot used to simulate human behavior on a product line. This ensures that the robot is stable and does not tip over, which is critical for safety and efficiency.

In addition to testing the CoG of a robotic arm, other tests for these types of robotics include the weight of the arm, the distribution of the weight of the arm, and the friction between the arm and the surface it is moving on. By considering these factors, it is possible to accurately determine the CoG of a robotic arm and ensure that it is stable and safe to operate.

There are many factors that can affect the accuracy of CoG testing using load cells, including the design, capacity and range of measurement of the load cells, the stability of the platform, and the distribution of the weight of the system.

CoG testing is an important part of the design and development of robotic systems. By determining the CoG of a system, it is possible to improve its stability and performance. If you are interested in learning more about CoG testing using Interface precision load cells, please contact us.

Industry 5.0 and the Role of Force Measurement

/0 Comments/in , /by

The next industrial revolution is coined Industry 5.0. The fifth wave of significant advancement comes on the heels of Industry 4.0, which focused on efficiency and productivity enhancements. The next revolution in our midst is heavily dependent on data, sensors, and enablement tools used for industrial automation. Of course, that means sensor solutions from Interface are perfectly aligned in facilitating the next advancements.

The use of artificial intelligence (AI), robotics, and other smart-enabled technologies are at the heart of Industry 5.0. To further automate and optimize production processes, there is a strong emphasis on human-centricity, sustainability, and resilience. Interface is working with industry leaders, integrators, and innovators to provide advanced sensor technologies that will support the adoption of Industry 5.0 products, with all the benefits of optimization and reliability.

One of the challenges in the design and implementation of Industry 5.0 solutions is interconnectivity. To maximize the connectivity between humans and machines, the equipment needs to be tested and monitored utilizing different sensors for adoption, efficiency and dependability. The use of robotics, AI, and other smart technologies are leading to sustainability in industrial and manufacturing facilities. This requires measurement data that is accurate and easily retained for continuous improvements. Learn more in our case study: Advancements in Robotics and Cobots Using Interface Sensors.

Wireless Enabled Force Measurement

The use of wireless and Bluetooth technologies is common for facilitating the connection between sensors and data analysis used in defining how these technologies are used in manufacturing and industrial environments. Using wireless load cells with wireless digital instrumentation, data is used for real-time adjustments and performance monitoring. This is particularly important in managing environmental worker safety working in collaboration with advanced machines and robots. Check out our WTS and BTS solutions for more options.

For robotics in particular, free range of motions is particularly important. This is standard in future use, especially as manufacturers grow in dependency in advanced robotics use cases across the manufacturing continuum. To test advanced robotics and accurate movement for different axes, multi-axis sensors are a smart choice due to their capabilities in simultaneously measuring 2, 3, and 6 axes at a time. These sensors are paired with data acquisition systems like our BX8 Data Acquisition System for Multi-Axis Sensors to fully utilize the depth of measurement data for better decisions.

We also help to enable automation across the production line. Our products test the quality, durability and accuracy in performance of machines and other equipment used for various functions across the line. This includes cases of using miniature load cells in equipment that rely on exact force to press a design on a fragile consumable, to verifying accuracy of intricately machined parts using multi-axis sensors for production lines. We have provided sensors for industrial automation solutions to thousands of customers using standard and custom application-specific sensors.

Industry 5.0 Applications Using Interface Solutions

Included below are a few Industry 5.0 applications in which Interface solutions have been used to test or monitor equipment.

Cobot Safety Programming

Collaborative robots, what are termed as cobots, are an Industry 5.0 advancement used in many manufacturing operations. With product testing and design enhancements based on sensor data, protective cages or fences are no longer needed for safety purposes. However, safety testing is required to ensure humans and robots can work alongside each other. For this application, Interface suggests using four 3A40 3-Axis Load Cells (creating one 6-Axis Force Plate) installed between two metal plates at the base of the cobot. In addition to installing the multi-axis force plate under the cobot, we also suggest using 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. Our BX8-HD44 BlueDAQ Series Data Acquisition System for Multi-Axis Sensors with Lab Enclosure is used to gather measurements and report back in real-time for monitoring.

 

6-Axis Force Plate Robotic Arm for Worker Safety

A customer wanted to measure the reaction forces of their robotic arm for safety purposes. The reaction loads occurred at the robotic arm’s base; therefore, they needed a force measurement system at the base of the robotic arm. Interface suggested using their force plate option to install at the base of the robotic arm. Four 3-Axis Force Load Cells are installed between two force plates, then installed at the bottom of the arm. This creates one large 6-Axis Force Plate. The sensors force data is recorded and displayed through the two BX8 Multi-Channel Bridge Amplifier and Data Acquisition Systems onto the customer’s computer. Interface’s 6-Axis Force Plate was able to successfully measure the reaction forces of the customer’s robotic arm while in action next to collaborating workers.

Commercial Food Processing for Efficiency

A food processing plant wanted accurate results of their in-motion check weigher when food is weighted and processed down the belt. They wanted to ensure production line efficiency and food quality. The customer also wanted real-time results of their food being weighed, and a load cell that could endure the food industry’s grubby environment.
