Torque sensors are divided into static torque sensors (rotation cannot exceed 360 degrees) and dynamic torque sensors. Static torque can be measured in both static and dynamic torque sensors. Static torque sensor is selected for cost consideration. If you measure the torque when the equipment is working dynamically, you can only choose the dynamic torque sensor to measure. Hefei Natural Intelligent Technology Co., Ltd. specializes in producing all kinds of torque sensors, can provide reasonable solutions in torque measurement.

If the torque value is measured at static, the range of the selected sensor is the same as the maximum load of the equipment when selecting the range of the torque sensor. When measuring the dynamic torque value (speed cannot be controlled by the power source), it is best to choose twice the maximum load torque value of your device when selecting the range of the torque sensor: because the device will produce a large instantaneous torque value when starting, a small range may damage the torque sensor. If a frequency converter controls the speed of the power source, select a torque sensor with a range larger than the maximum load torque value of the equipment.

Torque sensors can be divided into contact and non-contact two types. Non-contact torque sensor is also called sliding variable resistance torque sensor. The contact torque sensor is a torsion bar installed between the steering shaft and the steering pinion. When the steering system is working, the deformation of the torsion bar is measured by slip ring and potentiometer and converted into voltage signal. There are two pairs of magnetic pole rings in the non-contact torque sensor. When the relative rotation between the input shaft and the output shaft occurs, the air gap between the magnetic pole rings changes, which causes the change of the electromagnetic induction coefficient, enerates the induced voltage in the coil, and converts the voltage signal into the torque signal. The advantage of non - contact torque sensor is small size and high accuracy.
