Torque sensors, also known as torque sensors, torque sensors, torque meters, are divided into two categories: dynamic and static. Among them dynamic torque sensors can also be called torque sensors, torque speed sensors, non-contact torque sensors, rotational torque sensors, etc. A torque sensor is a device that detects the perception of torsional torque on various rotating or non rotating mechanical components. The torque sensor converts the physical changes in torque into precise electrical signals. Torque sensors can be applied in the manufacturing of viscometers and electric (pneumatic, hydraulic) torque wrenches. They have the advantages of high accuracy, fast frequency response, good reliability, and long service life.
