  • Anodic bonding method for making pressure sensor
    Patent number: 5695590
    Abstract: A pedestal mount capacitive pressure sensor (10) is supported in a housing (11) and used to sense fluid pressures to provide air pressure data relating to the performance of air vehicles. The capacitive sensor uses a thick base plate (40) on which a diaphragm (48) is mounted. A capacitive electrode (52) is mounted to the diaphragm and pressure deflects the diaphragm to provide an output. The pressure sensor (10) is mounted in an outer housing (11) using a stress isolating pedestal (20).
    Type: Grant
    Filed: June 7, 1995
    Date of Patent: December 9, 1997
    Assignee: Rosemount Inc.
    Inventors: Charles R. Willcox, Larry A. Peitersen
