Torque-Link-200

Introduction

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

Features & Benefits

High Performance

  • Lossless data throughput and synchronized node-to-node sampling of ±50 μS in LXRS+ and LXRS-enabled modes
  • Up to 1024 Hz sampling
  • Noise as low as 1 µV p-p
  • High resolution 24-bit data
  • Datalog up to 8 million data points

Ease of Use

  • Installs over existing strain elements and shafts with no mechanical modifications
  • Configurable housing geometry will accommodate any shaft size
  • Wireless data transmission allows installation on rotating components without a slip ring
