The Torque-Link-200 allows users to transform standard driveshafts into wireless torque transducers by application of one strain bridge. The node supports high resolution, low noise data collection from 1 differential input channel at a sample rate up to 1 kHz. An integrated hall effect sensor enables reporting of RPM and total pulses allowing for the derivation of real-time power in torque applications.

Product Highlights

  • Two to six inch diameter shaft (standard), more sizes available on request
  • One differential input channel (standard) for full-bridge strain gauge integration (two channels optional)
  • Ideal for static and dynamic torque measurements with full temperature compensation and bending cancellation
  • Alternative gauge configurations enable axial and bending measurements
  • Rugged ABS housing designed for remote, long-term installation on cylindrical shafts
  • Application-specific designs available on request
