摘要： 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.

摘要： A valve system includes a movable microelectromechanically structured (MEMS) pressure sensor that not only senses pressure but also functions as a mechanical actuator for the valve. An alternative valve system includes a MEMS pressure sensor that extends through an aperture in a curved wall, such as a curved wall of a valve body or a valve core, at an oblique angle to allow it be securely mounted in the confined space of an automotive-type tire inflation valve. The valve system includes a transmitter integrated with the valve and a receiver located at a remote location, such as the passenger compartment of an automobile.
