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, and the use of dynamic torque sensors is much larger than that of static torque sensors. The torque sensor range is a parameter that should be determined first when selecting a torque sensor.
How to determine the range of the torque sensor?
No matter what the sensor is, the range of the sensor must be determined first when selecting a model. Torque sensors are no exception. How to calculate when not sure about the range of the torque sensor? Let's talk about the calculation method of the dynamic torque sensor range.
The calculation formula of the torque sensor is generally as follows:
M=9550×P/N
Where M is the torque, the unit is Nm;
P is the motor power, the unit is kW;
N is the speed, the unit is r/min.
When selecting a torque sensor, if we don't know what range of torque sensor to choose, we can also calculate it through this formula.
It is necessary to understand the calculation formula of the torque sensor, because we often do not know what range to choose when selecting a torque sensor. Once we know this formula, we can calculate it well. Especially the sales staff of the torque sensor. This formula should be mastered so that we can help calculate it when the customer does not know what range to choose.
Of course, other factors must be considered when confirming the range. For example, if the motor used is a three-phase induction motor, due to the large instantaneous torque of the motor, it is recommended that the torque 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.
