the non circular shape will remain negligible but the sensitivity to pressure will be nearly increased proportionally to the increased size of the major diameter of the outer electrode accordingly this configuration allows a more sensitive sensor assembly to be packaged in a smaller diameter housing the substrate assembly preferably is fabricated by printing the cp 108 cr 110 and guard 120 electrodes and the cr 118 and cp 114 terminals onto the substrate 106 drying and firing them printing the sealing layer 112 drying the seal to drive off any volatile organic binders to leave a material that is approximately the consistency and hardness of chalk referring again to fig1 3 the diaphragm assembly 104 is shown comprising a diaphragm 120 a ground electrode 122 having a terminal 126 connected thereto and a sealing layer 124 a shield electrode which is on the bottom of the diaphragm assembly is not shown in a preferred embodiment the ground 122 and shield not shown electrodes and their terminals are fabricated by printing them onto the diaphragm 120 so that the electrodes are centered on the diaphragm 120 and correspond to the outer perimeter of the cr electrode 110 thereafter the electrodes are dried then fired once the electrodes have cooled the sealing layer 124 is printed and dried to drive off any volatile organic binders to leave a material that is.
