Abstract :
The authors discuss the requirements of a tyre pressure sensor. They then describe a sensor in which a wheel-mounted mechanism produces a displacement as a function of tyre pressure. This displacement is used to vary the separation of a pair of permanent magnets. The position of these magnets is sensed from the vehicle chassis by means of a Hall probe. The thermal compensation for the sensor, and laboratory and vehicle testing are also described
