Abstract: A sensor assembly includes a rectangular-shaped pressure sensor element and an electronic circuitry coupled to receive a signal from the pressure sensor element. An open-ended fluid-tight passageway of the sensor assembly conveys fluid from a portal opening of the sensor assembly to a surface of the rectangular-shaped pressure sensor element. The sensor assembly further includes a closed-ended fluid-tight passageway, at least a portion of which is fabricated from metal. The closed-ended fluid tight passageway extends from at least from the portal opening of the sensor assembly to the electronic circuitry on at least a portion of a path adjacent to the rectangular-shaped ceramic pressure sensor element. The sensor assembly includes a temperature sensor element disposed in an end of the closed-ended fluid-tight passageway. Conductive links disposed in the closed-ended fluid tight passageway electrically couple the temperature sensor element to the electronic circuitry.

Abstract: A combined fluid pressure transducer and temperature sensor (10) has a housing (12) containing a variable capacitor (14) having a rigid substrate (14a) and attached flexible diaphragm (14b) in sealed, spaced apart relation. The capacitor is mounted in the housing so that the outer face surface of the diaphragm is exposed to a fluid pressure chamber (12k). A temperature responsive sensor element (28) is disposed on the outer face surface of the diaphragm and covered by a thin protective layer. A fluid flow diffuser (30) is disposed in the fluid pressure port (12b) for directing fluid flow across the temperature sensor.
