Torque sensors with angle encoder unveiled

Sensor Technology SGR523 Torque Sensors feature a built-in angle encoder that suits a wide range of industrial and laboratory applications. The SGR523's design simplifies system architecture by combining torque and angle measurement into a single unit, reducing component count and enhancing system reliability.

Saelig Company, Inc. now offers the Sensor Technology SGR523, a state-of-the-art digital rotary torque sensor with an integrated incremental angle encoder. This innovative addition to the TorqSense SGR series adds a new capability for precision in torque and angular position monitoring across assorted industrial applications. The device employs non-contact strain gauge technology, eradicating the necessity for traditional slip rings and enhancing reliability. Its high-resolution angle encoder delivers up to 10,000 pulses per revolution with a remarkable resolution of 0.009°, making it exceptional for applications needing meticulous torque-angle analysis, such as mechanical testing, automated assembly, and process control.

Key features:

• Torque measurement range from 175mNm to 20Nm
• Accuracy of ±0.1%
• High mechanical overload capacity of 400%
• Overrange reading capability of 250%
• High digital sample rate of 4000 samples per second
• Digital outputs: RS232 and USB (standard); CANbus and Ethernet (optional)
• Bi-directional angle and rotation count
• Speed measurement up to 9000rpm
• Compatible with TorqView Advanced Torque Monitoring software
