Abstract :A Hall type tire inflation pressure sensor is designed , which is used to provide the input signal of tire pressure for the pressure monitoring and warning system of automobile tire. The sensor is comprised of the me2 chanical tire pressure transmitting mechanism , the magnetic and magnetic sensing elements , it can deliver tire pressure signal from the tire to the vehicle body without contact of the magnetic sensing element with the wheel. The structure features , the working principle , and the computing method for the design of the main componentsof the sensor are introduced.
Key words :sensor ; structure ; design ; tire inflation pressure ; monitoring
