A range of torque sensors that can measure and display high-speed detailed phenomena
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.
