__________________________________________________________________
 1. General_______ The system includes:
 -
a sensor which measures the pressure of each tire,

 -
a transmission unit which transmits the electrical pressure signal from the wheel (rotating) to the wheel axle (fixed). It includes a rotating transformer and an integrated electronic module,

 -
a computer.

 3. System Description__________________
 A. Description
 (Ref. Fig. 004)

 (1) Sensor The sensor is installed in a support attached to the wheel rim. The sensor is of the piezoresistive strain-gage type. An external voltage source supplies this sensor which gives a DC signal from O to 100 mV in proportion to the pressure. A four-wire cable which is shielded and twisted connects the sensor to the transmission unit.
