This sensor is perfect for industrial production and assembly applications where there is a need to measure actuating or breakaway torques, holding torques or tightening torques.
Its high measurement quality means that the sensor is equally suited to quality control applications and laboratory-based research and development projects.
For network-independent, mobile use, the torque sensor offers an optional USB interface. This can be connected to a notebook running the PC software supplied with this device to take on-site measurements with accompanying visualization and archival of measurement values.
The applied torque can be read easily by evaluation units or controllers connected to the normalized analog interface.
Its compact, robust and vibration-proof construction makes it suitable for use in the following example applications:
- Test setups for precision mechanics
- Measurements on micromechanical actuator elements
- Engine test benches including measurement of mechanical power
- Recording biomechanical movements in medical engineering
- Precision frictional torque movements on bearings
- Use as test-bench measuring device
