| Abstract: | The operating principles of the INSb magnetic resistor are analyzed. The semi-bridge magnetic resistor can be used to measure the rotating velocity and displacement by biasing magnetic field acted on it. As the semi-conductor is sensitive to the temperature, a method to use the shifting zero-point to test the rotating velocity of the gear made from magnetic material is presented. And its features are also discussed. |
| Keywords: | InSb magnetic-sensing resistor rotating velocity transducer temperature characteristics |
