Torque Sensors

PCB

®

offers an extensive range of strain-gage torque sensors for test, measurement, monitoring, and research & development applications.Both rotary torque and reaction torque measurements are accommodated with a variety of sensor configurations. Whether it’s an automotive dynamometer test or a hydraulic pump end-of-line quality assurance check, we can help, with sensors standard or customdesigned for your specific application.

Features and benefits of rotary transformer and digital telemetry signal transmission.

A primary challenge for rotary torque sensors is transferring the measurement signal from the rotating portion to the stationaryportion of the sensor. Two techniques are used by PCB

®

for rotary torque sensor signal transmission – rotary transformer anddigital telemetry. The rotary transformer is a non-contacting technique providing low maintenance and quiet operation. Digitaltelemetry offers noise-free operation and smaller size. For installations where space is a premium, the TORKDISC

®

, with digitaltelemetry, provides a shorter coupled installation.
