SGR510 or 520 Strain Gauge

New for 2020 is the TorqSense Digital rotary strain gauge series (SGR) Transducers use non contact technology eliminating the need for noisy slip rings. The SGR510 or 520 strain gauge series torque sensors are suitable for torque measuring, testing, feedback control of drive mechanisms and process control applications.

The SGR strain gauge series transducers use modern strain gauge signal conditioning techniques to provide a high bandwidth low cost torque measuring solution with high over range and overload capabilities.

Key Benefits – SGR510 or 520 Strain Gauge Torque Sensors:

• Transducers from 1Nm to 500Nm (with higher ranges to follow)

TorqSense SGR510 Series transducers offer:

• 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 transducers 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 transducers torque, speed ratings and calibrated 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
