Rotary Torque Transducer Rotary Torque Transducer Digital SGRSl0/520 series Torque Transducer Torqsense Digital rotary strain gauge series (SGR) Transducers use non contact technology eliminating the need for noisy slip rings. They are suitable for torque measuring, testing, feedback control of drive mechanisms and process control applications. The SGR series transducers use modern strain gauge signal conditioning techniques to provide a high bandwidth low cost torque measuring solution with high overrange and overload capabilities. FEATURES Transducers from 1Nm to 13000 Nm. Large fully functional overrange capability of 250% (SGR 520) Minimal side and end load errors Low linearity deviation of ± 0.05 % FSD Low hysteresis error of ± 0.05 % FSD Zero variation in torque signal with rotation (cyclic variation) Non contact signal transmission, no slip rings to wear out High digital sample rate of 4000 samples per second Adjustable torque data smoothness, low pass filter (SGR520) Speed measurement / Power computation Wide power supply range 12-32 VDC Compatible with ethernet gateway module Fixed voltage or current analog outputs (one for torque and the other for speed or power) for interfacing with analog instrumentation BIT Self-diagnostics for letting the manufacturer know that the transducer‘s torque, speed ratings and calibration due date have not been exceeded. Simple ‚Sensor status‘ output pin Sensors to monitor shaft temperature for better compensation and accuracy Whereas, TorqSense SGR520 series transducers offer: Digital outputs, such as RS232, CANbus and USB, for interfacing with modern instrumentation and laptops Digital input for configuring transducer via PC 2 x user selectable voltage or current analog outputs (one for torque and the other for speed, power or peak torque) for interfacing with analog instrumentation Transducer configuration software to allow user to change transducer variables BIT Self-diagnostics for letting users know data is trustworthy, that the transducer‘s torque, speed ratings and calibration due date have not been exceeded Simple ‚Sensor status‘ output pin Sensors to monitor shaft temperature for better compensation and accuracy Ability to connect up to 10 transducers using USB Optional external ethernet gateway module

Rotary Torque Transducer TECHNOLOGY The SGR series torque transducers use a full four element strain gauge bridge to measure the torsion present on a shaft. The full bridge helps to diminish errors from any offaxis forces that are sometimes unintentionally applied to the transducer in some test setups. The full bridge also increases the sensitivity and the temperature performance of strain measurement. A rotor mounted ultra-miniature microcontroller measures the strain gauge bridge and transfers the information back to the stator digitally eliminating any noise pickup usually associated with...
