Saelig Company, Inc. recently announced the TorqSense Digital RWT410/420 Series transducers with integral electronics, available in three different body sizes for torque ranges up to 13,000Nm. The new TorqSense RWT410/420 torque sensors, which replace the RWT310/320 series, feature performance gains in resolution, frequency response, reduced sensor current consumption and faster digital data throughput. Transducer overload capability has also been increased to 300 per cent. 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. Signal bandwidth is up to 10kHz at high (0.25 per cent) accuracy and resolution (0.02 per cent).
