LOW COST THICK-FILM PRESSURE SENSOR
A new type of pressure sensor for use in automobiles has been developed to take advantage of the piezoresistive effect of thick-film resistors screened-and-fired on ceramic diaphragms. The device consists of a ceramic diaphram bound around the edge, where in proper positions four resistors electrically connected, according to Wheatstone bridge configuration, are screened-and-fired. The deformation of the diaphragm because of an applied pressure causes bridge unbalancing and output signal proportional to the pressure itself.
