Miniature Rotary Torque Transducer

 

Description

The YDSA series of miniature rotary torque transducers have a shaft-to-shaft configuration and offer a very small size for mounting in compact spaces. They utilise a slip ring for excitation and signal transmission and offer low capacity torque measurement, high accuracy and high RPM capability.

Typical applications include the monitoring of high speed, low torque electrical motors and pumps.

For easy installation the YDSA features an integrated mounting pedestal and a detachable cable assembly.
