Rotational Torque Sensor (RTS)


The AD7832 Rotating Torque Sensor (RTS) leverages A&D's experience in distributed force detection, high-speed telemetry and digital signal processing technology to enable non-contact torque measurement at high-speed with high resolution. With certain models, rotational speed and angle can also be measured.


  • Dual range capability, where the full scale can be reduced to 1/5 of the rated capacity with the same accuracy.
  • Uses distributed force detection technology to achieve high accuracy.
  • Withstands torsion and bending, as well as severe radial and thrust load conditions
