Torque Sensors with Reduced Sensor Current Consumption

Featuring all new electronics, the TorqSense RWT430/440 torque sensors have offered considerable performance gains in frequency response, resolution, limited sensor current consumption, and quicker digital data throughput. Furthermore, the transducer overload has been increased to 300%.

The digital TorqSense RWT430 and RWT440 series employs the most modern and non-contact TorqSense technology similar to the one employed in the RWT410/420 Series in three distinct body sizes for torque ranges from 1 to 13,000 Nm, with even above 13,000 Nm on demand. This series is different from others in that it may be more suitable for some applications to have the sensor unit separate from the electronics unit because of space and/or environmental restrictions.

The series provides a cost-effective, non-contact digital rotary torque measurement solution, using TorqSense Surface Acoustic Wave technology, ideal for torque monitoring, testing, or controlling drive mechanisms and specifically suitable for OEM applications.

Key Benefits
