Tips: What factors affect the torque sensor output signal?
- The device of the torque sensor should ensure that the coaxiality between the motor end and the load end is within 0.03-0.05mm. When the torque sensor works under the condition of poor coaxiality, the output data of it will be unstable. Long-term work under this condition will damage the torque sensor.
- The field electromagnetic disturbance also has a great impact on the output signal of the torque sensor. The disturbance can be alleviated by connecting with an isolator to the power supply, or adding a magnetic ring to the cable.
- The unstable power supply will also affect the signal output of the torque sensor. You can use a unique switching power supply for the torque sensor.
Rotary torque sensor input and output end use flange connection, capacity range from 20 Nm, 50 Nm, 100 Nm to 5000 Nm. It is non-contact without the use of the bearing, which is suitable for high speed rotating or requiring short axial occasion.
