Application:
These BPM812 dynamic rotating torque sensors measure fast-changing torques at rotating shafts, and they are widely 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. Torque and power detection in sewage treatment systems;
5. Manufacture viscometers;
6. The process industry.
