A pressure sensor for sensing a pressure of a fluid includes a monolithic metal including substrate having a substantially planar top side, wherein the metallic comprising substrate includes s a relatively thick boss near a center of the substrate and a thinned sensing portion that is elastically deformable and pressure-sensitive positioned radially outward from the boss. At least one dielectric layer is on the top side of the substrate. A plurality of piezoresistors are on the dielectric layer, wherein the piezoresistors are positioned over the thinned diaphragm portion. At least one overglaze layer is over the conductor layer that provides apertures for electrically contacting the plurality of piezoresistors. A sensing system includes a housing including at least a first port for coupling to a fluid for measurement of a pressure of the fluid and at least one sensor in the housing including a pressure sensor according to an embodiment of the invention.

A method of incorporating compliant pins in a pressure sensor that uses PCB (printed circuit board) and is press fitted into the compliant pins. The compliant pins are made in the leadframe and the leadframes are molded into the plastic housing. The PCB is press fitted to the leadframe/housing assembly.
