  • Tire pressure monitoring system utilizing a pressure activated transducer and sensor
    Patent number: 5717135
    Abstract: A wireless tire pressure monitoring system is disclosed to warn a driver of a vehicle of low pressure in a vehicle tire. The monitoring system includes a transducer to which wires or other physical connections cannot be easily made. The transducer is attached to a wheel rim and a magnetic field can be selectively produced by elements of the transducer in response to changes in tire pressure. A sensor is mounted for sensing the magnetic field with the sensor producing an output that can be coupled with a monitor in the vehicle cab.
