What is the difference between dynamic torque sensors and static torque?

The difference between static torque sensors and dynamic torque sensors is not significant, but the key lies in the sampling speed of the secondary instrument.
Dynamic torque sensors are generally used to test situations where torque fluctuates significantly, requiring the implementation of torque capture or peak torque, such as tightening machines, electric wrenches, motor output torque, engine output torque, and drill pipe torque.
Static torque sensors are generally used to test situations where torque changes slowly, with a sampling speed generally less than 50 times per second, such as testing manual torque wrenches and static torque of transmissions.
In some cases, as the test object is rotating, dynamic torque sensors can also rotate for ease of testing.
The dynamic torque sensor can measure the electrical signal of the elastic shaft under torsion, and uses strain electrical measurement technology to form a strain bridge on the elastic shaft, thereby providing power to the strain bridge. After amplifying the signal, it undergoes voltage frequency conversion and becomes a frequency signal proportional to its corresponding frequency. The static torque sensor, on the other hand, converts the strain generated by the torque torque into an electrical signal linearly related to it based on the principle of resistance strain.
Torque sensors are mainly divided into two categories: static torque sensors and dynamic torque sensors. Static torque sensors cannot rotate beyond 360 degrees. If you need to measure the static working torque of the equipment, both static and dynamic torque can meet your measurement request. In order to save costs, we suggest that you choose a static torque sensor for measurement. If you need to measure the torque of the equipment during dynamic operation: you can only choose a dynamic torque sensor for measurement.
The application range of dynamic torque sensors is very common, which can be used for measuring torque in tractors, cars, airplanes, various ships, and mining machinery. It can also be used for measuring torque and power in sewage treatment systems, and is widely used in industrial and process industries. It also uses various rotating power equipment to detect torque and power output, such as electric motors, initiators, internal combustion engines, etc. Can be used to manufacture viscometers. The application range of static torque sensors is mainly used in testing systems such as experimental machines and static torque detection. So there is a certain difference between the two.
