    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. These small torque sensors utilise a slip ring for excitation and signal transmission and offer low-capacity torque measurement, high accuracy and high RPM capability.

    Thanks to the small torque sensors’ compact size, ideal applications include the monitoring of high-speed, low-torque electrical motors and pumps.

    For easy installation, the YDSA miniature rotary torque sensor features an integrated mounting pedestal and a detachable cable assembly.
