ABSTRACT:
A pressure sensor prevents the occurrence of a large deformation or breakage of the diaphragm in a strain gage-type pressure sensor utilizing a thin plate-shaped insulating body as the diaphragm. The pressure sensor comprises an insulating diaphragm having a strain gage on its surface and a substrate positioned opposing the surface of the diaphragm on which the strain gage is mounted and kept a predetermined distance away from the surface. The diaphragm can be formed of material such as ceramic of alumina, zirconia or the like, silicon or crystal. The substrate can be formed of either the same material as the diaphragm, or the surface opposing the diaphragm can be formed of an insulator disposed on metal. The diaphragm and the substrate can be affixed using a low-melting glass.
