How to calculate the range of a torque sensor

Torque sensors are widely used in the detection of torque, speed and power of motors, generators, reducers, and diesel engines. Torque sensors can generally be divided into dynamic torque sensors and static torque sensors. Dynamic torque sensors are much larger than static torque sensors. The torque sensor range should be determined first when selecting a torque sensor. How to determine the torque sensor range? No matter what sensor is now, the range of the sensor is determined first, and the torque sensor is no exception. How to calculate it when you don’t know the range of the torque sensor. Let’s talk about the range calculation method of the dynamic torque sensor and the calculation of the torque sensor. The formula is generally like this, M=9550×P/N, where M is torque, in Nm; P is motor power, in KW; N is speed, in r/min. This is the calculation formula of the torque sensor range, so if we don't know how to choose a torque sensor with a large range when selecting a torque sensor, we can also use this formula to calculate it.

It is necessary to understand the calculation formula of the torque sensor, because when we often choose the torque sensor, we don’t know how many ranges should be used. Once we know this formula, we can calculate it very well, especially if the salesperson should Familiarize with this formula so that we can help calculate it when the customer does not know how many ranges to choose. Of course, consider other factors. For example, if the motor you use is a three-phase induction motor, the torque is recommended due to the large instantaneous torque when the motor starts. The range should be selected to be 2-3 times the rated torque. Only by comprehensive consideration can a torque sensor with a suitable range be selected.
