How to choose a torque sensor correctly?

Want to make the right choicetorque sensor It needs to be judged from multiple aspects, starting from its category selection. Torque sensors can be divided into two types: dynamic and static. Static torque sensors are only suitable for measuring torque force values of static and discontinuous rotation. For torque measurements with too fast speed or rotation exceeding the 360 degree range, dynamic torque sensors need to be selected. Due to the fact that the price of dynamic torque sensors is much higher than that of static torque sensors, it is recommended to prioritize the use of static torque sensors when choosing static ones.

After selecting the category of torque sensors, it is up to the selection of sensor mileage and measurement accuracy.

The range of torque sensors can be divided into micro range, medium range, and large range. Considering that the degree of the sensor is calculated based on the full range, the range of the torque sensor should not be too large for the rated torque being measured to avoid significant errors during actual measurement. On the other hand, the range of the sensor must have sufficient margin for the measured object. Therefore, if there is a string vibration phenomenon in the measured torque, that is, the amplitude of the string vibration torque is superimposed on the steady-state torque, the range of the sensor is not greater than 1.5 times the measured torque; If the measurement is dynamic torque, the selected sensor range should generally be more than twice the rated torque.

In terms of the accuracy selection of torque sensors, it is necessary to choose the location where the sensor is used. If used in laboratory settings, it is recommended to choose torque meters with higher accuracy, and the accuracy level should not be lower than 0.5 or 1. However, if used in industrial sites, the accuracy requirements are not very high, and the accuracy level is generally 1, 2, or 3. Accuracy is also one of the main factors affecting the price of sensors.
