TorqSense® RWT410/420 Series Torque Sensors

TorqSense RWT410/420 torque sensors replace the RWT310/320 series and feature all new electronics that have produced significant performance gains in resolution, frequency response, reduced sensor current consumption and faster digital data throughput.
Transducer overload has also been increased to 300%.

TorqSense Digital RWT410/420 Series torque transducers with integral electronics are available in three different body sizes for torque ranges up to 13000Nm. The series offers a cost effective, non-contact digital rotary torque measurement solution, using TorqSense Surface Acoustic Wave technology, suitable for torque monitoring, testing or controlling drive mechanisms. TorqSense RWT410/420 series transducers and their technology are particularly appropriate for OEM applications.

If you require seperate electronics, please see our RWT430/440 Series transducers.

Rotary torque sensors manufactured by Sensor Technology Ltd

Key Benefits:

  • Minimal shaft length - High shaft stiffness
  • Low inertia - High Speed capability because electronics are not fixed on to shaft
  • Non-contact/brushless measurement - simple RF couple for power/signal transmission
  • High bandwidth 10kHz
  • 300% mechanical safe overload
  • High accuracy (0.25%) and resolution (0.02%)
  • Excellent noise immunity
  • Integral digital electronics
  • Operates both statically and dynamically - Clockwise and anti-clockwise
  • Any full scale torque can be specified within the standard range: 1Nm through to 13000Nm
  • Sensors to monitor shaft temperature for better compensation and accuracy
  • LED Status light
  • Lifetime Warranty

TorqSense RWT410 Series transducers offer:

  • Fixed voltage or current analog outputs (one for torque and the other for speed or power) for interfacing with analog instrumentation
  • BIT Self-diagnostics for letting the manufacturer know that the transducers torque, speed
    ratings and calibration due date have not been exceeded
  • Simple 'Sensor status' output pin
  • Sensors to monitor shaft temperature for better compensation and accuracy

Whereas, TorqSense RWT420 Series transducers offer:

  • Digital outputs such as RS232, CANbus and USB for interfacing with modern instrumentation and laptops
  • Digital input for configuring transducer via PC
  • 2 x user selectable voltage or current analog outputs (one for torque and the other for speed, power or peak torque) for interfacing with analog instrumentation
  • Transducer configuration software to allow user to change transducer variables
  • BIT Self-diagnostics for letting users know data is trustworthy, that the transducers torque, speed ratings and calibrated due date have not been exceeded
  • Simple 'Sensor status' output pin
  • Sensors to monitor shaft temperature for better compensation and accuracy
  • Ability to connect up to 10 transducers using USB
