About the ATF315 Miniature Reaction Torque Sensor
This static torque transducer is used extensively in instrumentation and small electric motor test and calibration applications.
Torque transmission must be arranged to input only torque as extraneous forces, such as tare loads or axial loads will cause measurement errors. Note we are able to calibrate with extraneous load cases replicated. The highly symmetrical signal outputs are usually between 0.2 and 1mV/V for full range.
We are happy to design variants of this transducer to meet your specific requirements. Please consult our engineering department. If you require a higher torque range than 5 Nm the ALF311 is available with ranges up to 1.000 Nm.
