The SGR series transducers operate using a four-element strain gauge wheatstone bridge, which is connected to a miniature shaft mounted analog to digital converter and microcontroller. The microcontroller conditions and measures the strain gauge bridge output as close to the gauges as possible, eliminating any possible external noise pick up in the gauge wiring.
The shaft mounted electronic module is wirelessly powered by a radio frequency source which drives a stator coil, the output of which is received by a rotor coil on the shaft thus making the system completely contactless. This eliminates the need for slip rings and their associated wear and noise problems.
The shaft microcontroller outputs a digital serial stream that is transferred back from rotor to stator by modulating the impedance of the rotor coil and detecting the impedance changes at the stator coil. A secondary high-performance microcontroller receives the serial stream from the shaft microcontroller, which then performs calibration and temperature compensation before outputting the results via the fixed analogue outputs
Torque ranges available at any full scale torque: 1Nm to 13,000Nm, with above 13,000Nm on request.
First Annual Recalibration is included in the purchase price. Units must be returned to Omni Instruments for Recalibration.
