System 4/5 Transducers

Sturtevant Richmont Torque Transducers

From the very beginning the tools we have manufactured and sold have been designed to mitigate human influence on torque application. 

Sturtevant Richmont torque transducers are also built to mitigate human influence on torque testing and calibration. The engineering and design are the keys to ensuring the most accurate torque tool calibration. 

What Makes SR Torque Transducers So Different?

Human influence that changes torque application comes in a number of forms. One of the most common human influences is called "side-loading."

Correct torque technique pulls the tool at exactly 90 degrees to the fastener. Any upward or downward pressure during that application or changes the actual torque output at the fastener.  In the cal lab the results are the same. That change in application technique changes the output at the transducer. 

To eliminate side loading Sturtevant Richmont has approached the issue from two sides. First, the torque wrenches are built with a flattened case shaft. That flattened case is significantly harder to side load.  

We realize that not all wrenches being tested on our equipment are built with a flattened case. We built our transducers with added stabilization to ensure no side loading. The smaller transducers have a cruciform support. The larger transducers have a ball bearing ring around the transducer to ensure that force is only applied at a 90 degree angle. 

In building the new System 8 we have kept some of the System 4/5 transducers where it made sense. We also added new transducers that will only work with the System 8. 

If you have a System 4/5 we have a complete line of transducers for you. Some of the names may have changed, but the range, functionality, foot print, accuracy, and durability are the same.

Here is a chart of transducers that work with the System 4/5. Buying one of these transducers ensures you have the right fit.
