Rotary Torque Sensor

M425 rotary torque sensor with keyway shafts offers high accuracy of 0.1% and torque measurement range from 0-10Nm up to 60,000Nm as standard. It’s an inline rotation torque transducer, widely used for motor, gearbox and pump torque testing.

Using a highly-accurate non-contact technique, the Datum M425 Rotary Torque Transducer and Torque Meter represent an ultimate torque sensor for anyone looking to measure torque, power, and speed with high accuracy and repeatability.

Rotational Torque Transducer Measurement

The M425 rotating torque sensors give the customer control over their tests with digital torque sample rates selectable at any time from 1sps up to 4,000sps as standard and analogue sample rates of 20sps.

M425 Rotary Torque Transducer Range

Why we think this is the best torque sensor on the market?

Firstly, the  M425 Torque Sensors have 14 standard torque ranges, covering from 3 Nm to 60,000 Nm.

Having a rotating torque measurement design with an optimum length to maximise overall accuracy and give a high degree of tolerance to mounting offset, the M425 digital torque sensor is ideal for most general test rig applications, like electric motor testing, pump torque testing, gearbox testing (to name just a few).

M425 Torque Sensor Features:

  • Accuracy: 0.1%
  • Non-Linearity: 0.1%
  • Repeatability: 0.05%
  • Digital Sample Rate: 1 to 4000 samples per second
  • Serial Torque Outputs: SCADA outputs, including RS485, RS232, Ethernet, Modbus UPD, USB Logging
  • Analogue Torque Outputs: 4-20mA configured 4-20mA (4-12-20mA): +/-10Vdc, +/-5Vdc, 0-10Vdc or 0-5Vdc at 20 samples per second
  • Operating Range: -10 to +70˚C
  • Environmental Protection: IP54 (see our high-speed RS425 Torque Sensor for IP67/68)
  • Power Supply: 10-24Vdc 250mA
