TorqSense® RWT430/440 Series

The NEW TorqSense RWT430/440 torque sensors replace the RWT330/340 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%.

The digital TorqSense RWT430 and RWT440 Series use the latest and same non-contact TorqSense technology as used in the RWT410/420 Series in three different body sizes for torque ranges from 1Nm to 13,000Nm, with above 13,000Nm on request. The only difference for this Series is that it may be more appropriate for some applications to have the sensor unit separate from the electronics unit due to space and/or environmental limitations.

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 and particularly appropriate for OEM applications.

If you require integrated electronics, please see our RWT410/420 Series transducers.

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
  • 300% mechanical safe overload
  • High accuracy (0.25%) and resolution (0.02%)
  • Excellent noise immunity
  • Seperate 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 13,000Nm
  • Lifetime Warranty

TorqSense RWT430 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 transducer 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 RWT440 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 the manufacturer know that the transducer 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
  • Ability to connect up to 10 transducers using USB
