Call for price


The AD7832 series is a range of torque sensors with distributed force detection, created with A&D’s DSP technology and high-speed telemetry technology.

The series can measure and display high-speed detailed phenomena faster and at a higher resolution than conventional sensors. The Rotation Torque Sensor is designed for in shaft torque measurement e.g. as used for test beds for powertrain development.

Product Features

  • Torque sensor featuring 1/3000 high resolution and robust construction
  • Robust against vibration: Sensor can be installed to Engine output shaft without intermediate bearing.
  • Real torque measurement using component force measurement
  • Dual range with high accuracy (without degrading the total accuracy)
  • Nominal torque: 200Nm – 5kNm
  • Combined error: 0.03%
  • Dual range: Combined error of 1/3000 is guaranteed at 1/5 of full scale
  • Maximum rpm: 12,000 rpm (200 Nm) – 10,000 rpm (5 kNm)
