Rotary torque sensor: how to choose the right model

Rotary torque sensors, also known as torque transducers, allow for the precise measurement of torque on rotating shafts, motors, gearboxes, and test benches.

In industrial applications, selecting the correct sensor is key to avoiding measurement errors, premature wear, or unstable readings.

Common applications

Electric motor testing
Automotive test benches
Torque control in production lines
Measurement in rotating machinery

Types of torque sensors
There are different technologies depending on the application:

Strain gauge sensors
Magnetoelastic sensors
Contactless sensors for high speed

Common mistakes when measuring torque

Poor shaft alignment
Use of static sensors in dynamic applications
Influence of vibrations or axial loads
Incorrect selection of the measurement range
