The sensor range selection

The selection of the measuring range of the torque sensor should be based on the actual measurement of the maximum torque, under normal circumstances should be left a certain margin, to prevent overloading cause damage to the sensor.

The formula: M = 9550 × P / N

M: Torque Units: N.m.

P: Motor Power Unit: KW

N: Rotation speed Unit: r / min

If you are using a three-phase induction motor, due to the motor starting a large instantaneous torque, the proposed torque range should be selected to 2-3 times the rated torque.
