  • Patent number: 4711130
    Abstract: A pressure measuring element includes a plate-shaped substrate of ceramic material and a membrane deformable in response to pressure fluctuations. The membrane is made of ceramic material and is mounted to the upper side of the substrate. A pressure-sensitive resistor for measuring pressure is positioned inside the membrane. A heating resistor element is positioned on the underside of the substrate, which maintains the temperature of the substrate constant. A temperature sensor is also arrayed on the upper side of the substrate near the membrane.
