Abstract

A system for measuring the pressure in a rotating tire and transmitting the information via magnetic pulses to a sensor pickup located near the tire, but on a non-rotating part of the vehicle, for transmittal via wire to a micro controller for conversion to air pressure units and display.

Claims

1. A sensor for measuring the air pressure in a rotating tire on a moving vehicle which produces a series of magnetic pulses which can be processed and displayed as tire air pressure.
