The TorqSense Digital RWT410/420 Series transducers with integral electronics is available in three different body sizes for torque ranges up to 13,000 Nm. The new TorqSense RWT410/420 torque sensors, which replace the RWT310/320 series, feature significant performance gains in resolution, frequency response, reduced sensor current consumption, and faster digital data throughput. Transducer overload capability has also been increased to 300%. 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.
Benefits of the new range include: Minimal shaft length for high shaft stiffness, low inertia offering high speed capability, non-contact and brushless measurement without electronics fixed to the shaft. Power and signal are transmitted to the sensor via a simple RF coupling. Signal bandwidth is up to 10kHz at high (0.25%) accuracy and resolution (0.02%). Excellent noise immunity comes from integral digital electronics and the RWT410/420 series which operates statically and dynamically (clockwise and counter-clockwise) for any specified full-scale torque (series range 1Nm through to 13,000 Nm.) Built-in sensors monitor and compensate for shaft temperature.
TorqSense RWT410 Series transducers offer voltage or current analog outputs for torque and speed or power for interfacing with analog instrumentation, whereas, The RWT420 Series transducers provide digital outputs (RS232, CANbus or USB) for interfacing with modern instrumentation and PCs.
TorqView, free with the RWT410/420 Series transducers, is easy to use, visual torque monitoring software that provides data recording and instrumentation displays for Windows based PCs. Its features include: 3 types of display, text files compatible with Matlab and Excel, and real-time chart plotting. Price/unit: $2,000.
