US Patent:

56955901, Dec 9, 1997
Filed:

Jun 7, 1995
Appl. No.:

8/486309
Inventors:

Charles R. Willcox - Eden Prairie MN
Larry A. Peitersen - Chaska MN
Assignee:

Rosemount Inc. - Eden Prairie MN
International Classification:

B32B 3114
US Classification:

1562722
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).
