Recap of New Twist on Torque

In our latest virtual event New Twist on Torque, Randy White and Keith Skidmore shared valuable insights and tips using this type of sensor. With more than 50 different types of torque transducers available at Interface, this webinar highlighted the differences, specifications, use cases and integration advice from our experts.

The ForceLeaders webinar started off with a quick rundown on the history of torque from the first dynamometers measuring the torque and RPMs of motors to the revolutionary Interface AxialTQ. In fact, you can now see how this rotary torque transducer is actually being used in today’s advanced engine dynamometers solution here. The conversation quickly lead to multiple design options and progressed to vital integration tips, considerations and common questions.

By definition, torque transducers convert a mechanical input of torque to an electrical output signal where the signal is directly proportional to the torque input. They consist of a metal spring element like a load cell. The strain gages are bonded to the flexure in a Wheatstone bridge configuration. As torque is applied to the sensor, bending or shear strain in the gaged area, it causes the strain gages to change resistance and generate an output voltage signal proportional to torque. You can read more about torque basics in our Torque Transducers 101 post.

Throughout the event, our experts shared important know-how in using the various types of transducers, including rotary, reaction, miniaturized and even custom-built products. Reaction sensors, also referred to as static, measure torque without rotating. A rotary sensor, also called dynamic, rotates as part of a system. It is merely a reaction sensor that’s allowed to rotate. And yes, you can customize torque transducers to fit your exact requirements. You can see all our torque products here.

Keith detailed four important considerations related to capacity: drive service factors, load service factors, stopping and starting conditions and extraneous loading. There was a robust discussion about fixed and floating mounting options and the importance of couplings. Randy highlighted all the products available and also gave a great recap of several real use cases across various several industries including energy markets, automotive and vehicles, robotics and more.

Be sure to watch the entire event for an abundance of firsthand knowledge and expertise based on working with thousands of customers using torque transducers all types of applications.

Load Cell Basics

 

Recap of Use Cases for Load Pins Webinar

Interface load pins continue to grow in demand as an easy to integrate and cost-effective sensor solution for many diverse applications as direct replacements for clevis or pivot pins. Most commonly used for lifting and rigging mechanisms in construction, structural assemblies and moving devices, load pins are typically used in rope, chain and brake anchors, sheaves, shackles, bearing blocks and pivots.

To provide greater insights and answers to questions asked to our force measurement application experts, Interface hosted a ForceLeaders Forum event, Use Cases for Load Pins. The event, now archived on our YouTube channel, highlights why more and more industries are using load pins include for projects related to infrastructure, aerospace and defense, industrial automation, manufacturing, maritime, and in energy markets such as oil and gas.

Regional Sales Director Elliot Speidell covered a series of topics in this live event, which included:

  • Who is Using Load Pins and Why?
  • Models and Design Aspects of Load Pins
  • Integration Considerations
  • Installation Factors
  • Load Pin Capabilities including Wireless Features
  • Standard and Customization Options
  • New-Found Applications Using Load Pins
  • Differences and Advantages
  • FAQs

WATCH NOW: THE ‘USE CASES FOR LOAD PINS’ ON-DEMAND EVENT

This webinar covers great detail in installation tips, integration considerations, design features and more.  Here are just a few highlights from the webinar.

Load pins measure tensile and compression forces via strain gages that are installed within a small bore through the center of the pin. Two grooves are machined into the outer circumference of the pin to define the shear planes, which are located between the forces being measured. They are made of rugged stainless-steel material and are commonly used for safety applications.  They are easy to retrofit and inherently waterproof by design, making it useful in submersible and adverse environmental conditions. Load pins have multiple bridge options and can be cabled or wireless.

One of the most important features and distinctions of a load pin is the ability to customize the design to fit the application. Due to the nature of requirements and fact most load pins are custom solutions, they often do not have any charges for NRE. Contact our application experts to learn of the possibilities and design options.

When installing a load pin various factors need to be considered which can influence the performance or accuracy. The fit of the pin within a structure is important to the overall performance of the load pin. For an optimal performance, an H7/g6 clearance would normally be recommended; however, this is not always achievable in the field and some slight loss of repeatability and linearity can normally be tolerated to achieve an “easy to fit” requirement.

Load pins are a great sensor to use in a “smart system” application for automated feedback, alarms, and real-time notifications.  They integrate with all types of instrumentation, including digital output options. Though they are simple and easy to use, they are known for hardiness. It is important to understand they are not “precision performance” devices, they are designed for standard force measurement applications that require immediate feedback. Also, they are easy to incorporate with existing actuator set-ups.

Dimensions of Multi-Axis Sensors Virtual Event Recap

The Interface ForceLeaders hosted forums are designed to answer frequently asked questions from testing engineers and product designers about new technologies and uses cases. In our recent virtual event, Dimensions of Multi-Axis Sensors, we discussed the considerations for these types of sensors, the test and measurement benefits, products Interface offers and various applications.

Interface recognizes that there are growing demands for multi-axis sensors.  In our hosted event, Interface’s Brian Peters kicked-off the conversation by highlighting benefits and reasoning for the use of these types of sensors, including answering some common questions. We’ve provided a recap of the event below or you can watch the event here https://youtu.be/zua1lvTh488.

What is Unique about Multi-Axis Sensors?

Multi-axis sensors have additional bridges to provide output signals for varying axes or types of mechanical loading. They are designed to measure a multitude of forces and moments simultaneously with a single load cell sensor. Fundamentally similar to other force and torque sensors with strain gage bridges bonded to machined “flexures,” each bridge typically defines a measurement axis. 

There are multiple configurations of 2, 3, or 6-axis options.

  • Axial + Torque
  • Axial + Shear
  • Axial + Moment
  • All 6 degrees of freedom

Should You Use Multi-Axis Sensors?

The largest factor to consider is the accuracy of your test model. In many test applications using standard load cells we often notice side or eccentric load, which can skew your data. While many Interface load cells, particularly mini load cells, have been designed to reject indirect loads, nothing can handle side and eccentric loads quite like a multi-axis sensor. Dedicated multi-axis designs are typically more balanced axis capacity limits with discrete signal outputs. Composite signal outputs are common in 6-axis models.

What are the Benefits of Multi-Axis Sensor Technology?

There are a number of benefits to using multi-axis sensors in addition to accounting for and accurately measuring or rejecting side and eccentric load. These benefits include:

  • Consolidate measurement signals, conserve test space
  • Measure unwanted system crosstalk
  • Quantify reaction loads through test article on “non-measure” side 
  • More successful fatigue testing through setup and load verification
  • More data, more understanding, more complete picture

What Considerations Should Engineer Make When Using Multi-Axis Sensors?

If you’ve made the decision to utilize a multi-axis sensor in your test model, please note the following considerations:

  • System-level loads and geometry
  • Maximum loading conditions
  • Chosen capacity is adequate for measurement loads as well as potential peak or extraneous loads
  • Choosing the right sensor based on primary axis measurements

Interface Multi-Axis Sensor Products

Ken Bishop details various types of multi-axis sensor technology from Interface during the highlighted ForceLeaders event you can watch here.  Interface offers a wide range of multi-axis sensors, including 3-axis, 6-axis, axial torsion and 2-axis versions. The product options give you the ability to measure forces simultaneously in three mutually perpendicular axes, with the 6-axis load cells also measuring torque around those axes.

AXIAL TORSION LOAD CELLS

Interface’s axial torsion load cell is used for measuring both torque and force in a single sensor. Typical applications of its axial torsion transducer include bearing test and material test machines. The features of our axial torsion load cell include minimal cross talk, extraneous load resistance, and the load cell is fatigue rated. Customers can also add the following options: an integral cable, compression overload protection, and connector protectors.

2-AXIS LOAD CELLS

The Interface 2-Axis load cells can measure in two directions, X and Y simultaneously. It is commonly used in applications where dual-axis measurement is important in design and testing. They are effective for applications that measure lateral forces and the narrow design fits into compact areas.

2-Axis Interface Products:

3-AXIS LOAD CELLS

Interface’s 3-axis load cell measures force simultaneously in three mutually perpendicular axes: X, Y, and Z – tension and compression. Each axis provides a unique mV/V output and requires no mathematical manipulation. The 3-axis load cell is built to minimize eccentric loading effects and crosstalk between axes. We offer five different models in its 3A Series 3-axis load cell designed for a wide variety of capacities. They are compact in size, provide 3 full bridge mV/V outputs with an IP68 option.

3-Axis Products:

6-AXIS LOAD CELLS
