Abstract
A valve/transducer and system for pressure measuring: which has a valve/transducer (24) comprised of an appropriately dimensioned tapered barrel (30) of rigid material with a gasket (40) near the barrel's larger diameter proximal end. The valve/transducer has an opening closable by valve cup (32) which is operated by a pin (34) extending from the barrel. The valve/transducer has within the barrel an integrated silicon circuit (44) and flex circuit electrical interface (76). The integrated circuit provides a pressure transducer (58) and an integrated processor/encoder (68). The system includes wireless transmitter/receiver paired circuits consisting of a transponder (26) and a transmit/receive channel circuit (164). The system includes a control/display processor (162) and an indicator (182) with novel displays of useful tire inflation and maintenance parameters.
