RWT430/440 Series Torque Transducers

Non-contact /brushless Torque Sensors with Digital Output

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 13000Nm, with above 13000Nm 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.

Key Benefits:

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

TorqSense RWT430 Series transducers offer:

• Fixed voltage or current analog outputs for interfacing with analog instrumentation (one for torque and the other for speed or power)
• 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

TorqSense RWT440 Series transducers offer:

• Options of RS232, CANbus and USB for PC and instrumentation digital interfacing
• Digital input for configuring transducer via PC
• 2 x user selectable voltage or current analog outputs for interfacing with analog instrumentation (one for torque and the other for speed, power or peak torque)
• 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
