Dynamic torque sensor is a precision measuring instrument that measures various torques, speeds, and mechanical power. The application scope is very wide, mainly used for: 1. Detection of output torque and power of rotating power equipment such as electric motors, engines, and internal combustion engines; 2. Testing of torque and power of fans, water pumps, gearboxes, and torque wrenches; 3. Testing of torque and power in railway locomotives, automobiles, tractors, airplanes, ships, and mining machinery; 4. Can be used for torque and power detection in sewage treatment systems; 5. Can be used to manufacture viscometers; 6. Can be used in process industry and process industry.
