TorqSense Digital RWT310/320 series transducers with integral electronics are available in three different body sizes for torque ranges up to 10,000Nm. The series offers a cost effective, non-contact digital rotary torque measurement solution, using Surface Acoustic Wave technology, suitable for torque monitoring, testing or controlling drive mechanisms. TorqSense RWT310/320 series transducers and their technology are particularly appropriate for OEM applications.

Key Benefits

• Minimal shaft length - High shaft stiffness
• Low inertia - High Speed capability because electronics are not fixed on to shaft
• Non/contact measurement - simple RF couple for power/signal transmission
• High bandwidth
• 200% mechanical safe overload
• High accuracy and resolution
• 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: 500mNm through to 10,000Nm
• Sensors to monitor shaft temperature for better compensation and accuracy
• Lifetime Warranty

TorqSense RWT310 Series transducers offer:

• Fixed voltage or current analog outputs (one for torque and the other for speed or power) for interfacing with legacy analog instrumentation
• BIT Self-diagnostics for letting the manufacturer know that the transducer torque or speed ratings have not been exceeded and the transducer's calibration date
• Simple 'fail' output pin

Whereas, TorqSense RWT320 Series transducers offer:

• 2 x user selectable voltage or current analog outputs (one for torque and the other for speed, power or peak torque) for interfacing with legacy analog instrumentation
• Digital outputs such as RS232 and USB for interfacing with modern instrumentation and laptops
• Digital input for configuring transducer via PC
• BIT Self-diagnostics for letting users know data is trustworthy, that the transducer torque or speed ratings have not been exceeded and the transducer's calibration date
• Transducer configuration software to allow user to changes transducer variables
• Ability to connect up to 10 transducers using USB
• Simple 'fail' output pin
