- 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
- Lifetime warranty
The SGR523’s advanced capabilities enable engineers to detect mechanical anomalies, such as rotational stiction or thread damage, by analysing torque versus angle plots. This dual-parameter monitoring is crucial for quality assurance in manufacturing processes, including bottle cap tightening and bolt fastening.
Additionally, the sensor’s ability to monitor torque at specific shaft angles aids in identifying potential issues in process control applications, thereby reducing production wastage. Its high-resolution angle measurement also facilitates precise motion control, allowing for better management of inertia in motion platforms and improved safety in automated machinery.
The SGR523’s design simplifies system architecture by combining torque and angle measurement into a single unit, reducing component count and enhancing system reliability. Its robust construction and advanced diagnostics, including Built-In Test (BIT) self-diagnostics and shaft temperature monitoring, ensure consistent performance even in demanding environments.
