  • Patent number: 8656784
    Abstract: An enclosed, flat covered leadless pressure sensor assembly suitable for extreme environment operation including dynamic, ultra-high temperature heating, light and heat flash, and high-speed, flow-related environments. The pressure sensor assembly comprises a substrate comprising a micromachined sensing diaphragm defined on a first side. A cover is attached to the first side of the substrate such that it covers at least the sensing diaphragm. The top surface of the cover is substantially flat, thereby promoting uniformity in the distribution of stress and thermal effects across a top surface of the cover.

  • Patent number: 7779682
    Abstract: A pressure transducer, particularly adapted to measure the pressure in a tire and to enable the tire to be filled includes a first housing, having an internal hollow. Positioned in the hollow of the first housing is a second housing, also having an internal hollow. The second housing is supported within the first housing so that a passageway for airflow exists between the housings. The second housing has a pressure port for monitoring the pressure of a tire. The first housing has an inlet port for receiving a source of pressure. The inlet port contains a valve which is selectively operated. The valve, when operated, permits air to flow into the hollow of the first housing and to flow about the periphery of the second housing to enter the pressure port associated with the second housing. The pressure port may, as indicated, be associated with a tire and the second housing contains a pressure sensing device which monitors the pressure in the tire via the pressure port.

  • Patent number: 5999082
    Abstract: A pressure transducer employing a metal isolation diaphragm. A volume of oil is located between the metal diaphragm and a silicon sensor received in a base member. In order to reduce errors at very low pressure caused by the oil exerting a tension on the deflecting portion of said silicon sensor, the metal diaphragm has an extending dome or dimple above the location of the silicon sensor. The silicon sensor is also recessed below the supporting base plate so that the separation between the silicon sensor and the metal diaphragm increases. The base plate also contains a series of shallow, narrow concentric grooves which further reduces surface tension between the metal diaphragm and the base plate.
