RWT410/420 Series Torque Sensors

Non-contact /brushless Torque Sensors with Digital Output

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.

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 RWT410 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 RWT420 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
