Which is better for torque sensor manufacturers?

Torque sensors are primarily used to measure various torques, speeds, and mechanical efficiencies. It converts torque changes into electrical signals whose accuracy is related to the accuracy of the test system. Its main features are not only the measurement of static torque, but also the rotational and dynamic torque. High detection accuracy, good stability, strong anti-interference ability; continuous measurement of forward and reverse torque, no need to repeat zero adjustment, no conductive parts such as conductive rings, can run at high speed for a long time; its output high frequency signal can be sent directly The computer processes it. Torque changes in mechanical power equipment are important information about their operating status.


The non-contact torque sensor is also a dynamic torque sensor, also known as a torque sensor, a torque speed sensor, a rotary torque sensor, and the like. The input shaft and the output shaft are connected by a torsion bar, the input shaft is connected by a spline, and the output shaft is connected by a keyway. When the torsion bar is twisted under the action of the rotational moment, the relative positions of the spline and the keyway are changed, and the change in their relative displacement is the torsion of the torsion bar. This process changes the magnetic induction on the spline and converts it into a voltage signal through the coil. The non-contact torque sensor has the characteristics of long service life, high reliability, low wear resistance, low time delay, small influence by the shaft, and wider application.

The strain gauge torque sensor uses strain gauge technology and its principle is to form a measuring bridge with an elastic shaft and a strain gauge. When the elastic shaft is slightly deformed under the action of the torque, the resistance value of the bridge will change, and then the electrical signal will change to achieve the torque measurement. The strain gauge torque sensor features high resolution, small error, large measuring range, low price, easy selection and large range of use.

1. Determine the type of torque to be measured, whether it is rotational torque or static torque. Static torque measurement refers to the case where there is no rotation or the rotation angle is less than 360 degrees.

2. In addition to torque, do you need to measure other parameters, such as speed.

3. There are several types of general torque sensor ranges, such as micro range, standard range, and large range. The trajectory range is typically less than 2 nanometers; the mass range typically exceeds 10,000 nanometers. The middle is the standard range.

4. Signal type and signal processing mode The output signal of the general torque sensor is 5-15 kHz or 4-20 mA or 1-5V. According to the actual situation, whether the output signal is sent directly to the programmable controller or the display display instrument.
