  • Pressure transducer
    Patent number: 7171857
    Abstract: One aspect is a pressure transducer package comprising a housing, a diaphragm, a support disposed in the housing and a sensing element disposed in the housing between the diaphragm and the support so that the pressure from the environment acts on the diaphragm to compress the sensing element. The sensing element comprises at least one substrate having a coefficient of thermal expansion greater than 4 ppm/k. In another aspect, the sensing element comprises at least one substrate formed of a first material and an epitaxial layer of a second material having a lower coefficient of thermal expansion. In a further aspect, the support abuts the housing at a spherically-shaped interface to compensate for misalignment between the support and the sensing element to ensure that the sensing element is evenly loaded.
    Type: Grant
