Torque Transducers with Minimal Shaft Length

Incorporating all new electronics, the TorqSense RWT410/420 torque sensors have yielded considerable performance gains in frequency response, resolution, more rapid digital data throughput, and decreased sensor current consumption.

In addition, transducer overload has been improved to 300%.

TorqSense Digital RWT410/420 Series torque transducers with built-in electronics come in three distinct body sizes for torque ranges of up to 13,000 Nm. The series uses TorqSense Surface Acoustic Wave technology, ideal for torque monitoring, controlling, or testing drive mechanisms to provide a less expensive, non-contact digital rotary torque measurement solution. The TorqSense RWT410/420 series transducers and their technology are particularly ideal for OEM applications.

Key Benefits

Low inertia — high-speed potential as electronics are not mounted to the shaft

Least shaft length — high shaft stiffness

High bandwidth 10 kHz

Non-contact/brushless measurement — simple RF couple for power/signal transmission

High resolution (0.02%) and accuracy (0.25%)

Mechanical safe overload of 300%

Built-in digital electronics

Outstanding immunity to noise

Any full-scale torque can be specified within the standard range: 1 to 13,000 Nm

Works both dynamically and statically — anti-clockwise and clockwise

Sensors to track shaft temperature for improved compensation and accuracy

Lifetime warranty

LED status light
