ABSTRACT:
A resistive strain gauge pressure sensor including upper and lower housings coacting to define a pressure chamber within the housing. A board member assembly is clamped between the housings and defines a diaphragm portion which extends across the pressure chamber to divide the pressure chamber into upper and lower chamber portions. The board member assembly includes a relatively thin plate member, including a diaphragm portion, and a relatively thick support member bonded to the upper face of the thin plate member and including an annular portion positioned in surrounding relation to the diaphragm portion. The circuitry of the sensor is screen printed onto the lower face of the plate member and includes the various resistor elements of the strain gauge assembly, the various elements of the conditioning circuit receiving the output of the strain gauge assembly, and the various further leads required to connect the circuitry elements to the terminals of the sensor. The sensor terminals are provided by a plurality of connector pins extending downwardly through the plate member for connection at their respective lower ends to the circuitry provided on the lower face of the plate member.
