Rotary torque sensor installation:

Tips: How to install a rotary torque sensor?
The steps of torque sensor installation:
- According to the connection form of the shaft and the length of the rotary torque sensor, determine the distance between the prime mover and the load. Adjust the distance between the axes of the prime motor and the load relative to the base level, enable the axes concentricity to be less than Φ0.03 mm. Fix the original motor and load on the base level.
- Install the couplings on the shafts respectively.
- Adjust the distance between the torque sensor and the base level, enable the concentricity of their axis (torque sensor, motor and load) to be less than Φ0.03 mm, and fix the torque sensor on the base level.
- Tighten the coupling and complete the installation.
The requirements of torque sensor installation:
- Power equipment, torque sensor, and load equipment should be installed on a stable foundation to avoid excessive vibration, otherwise, data instability, measurement accuracy reduction, and even damage to the dynamic torque sensor will probably occur.
- Choose the elastic pin coupling or rigid coupling for connection. When the vibration is serious or the concentricity is greater than 0.05mm, it is recommended to use a flexible coupling and install a bearing support at the left and right ends of the torque sensor.
- Adjust the centre height and concentricity of the power equipment, load, and torque sensor separately, which is required to be lower than 0.05mm, and then fix.
Matters needing attention:
- The torque sensor should be installed in an environment where the ambient temperature is 0 ℃ ~ 60 ℃, the relative humidity is less than 90%, and there is no flammable or explosive product.
- It is not suggested to be installed in an environment with strong electromagnetic interference.
