Title 2
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
