Abstract

A pressure system for monitoring the pressure in tires and other pressurized devices, is mounted in a position to receive pressure. A tire monitoring device structure is provided in which an average user can attach to the tire pressure stem. Internal pressure is monitored and transmitted to a receiver which is programmable to receive the signal and utilize it to provide information and warnings to the vehicle operator should the tire pressure (1) attain a value outside tolerance limits, or (2) become unmatched beyond relative tolerance limits.

Claims

1. A tire pressure system transmitter comprising:

a main housing having a first and a second end, said first end including for fitting over a conventional tire valve stem;

a pressure sensor mounted within said main housing;

a transmitter connected to said pressure sensor for receiving a sensed pressure and transmitting a signal associated with said sensed pressure;

a pressure pin extension adjacent said second end of said main housing positioned to depress a valve stem pressure pin upon attachment of said tire pressure system transmitter.

2. The tire pressure system transmitter as recited in claim 1 wherein said main housing further comprises a mechanical barrel assembly and an electronics housing section.

3. The tire pressure system transmitter as recited in claim 2 wherein said pressure sensor further comprises a pressure displacement diaphragm within said mechanical barrel assembly, a transducer pushing structure operable between said mechanical barrel assembly and said electronics housing section, and a transducer within said electronics housing section.
