Abstract: A media compatible package (100) for a pressure sensing device is made from a non-corrosive, highly chemical resistant material. The package includes a base (105) which holds a printed circuit board (115) having a pressure sensor (18) mounted thereon. A sealing member (45) is placed on the circuit board encircling the pressure sensor and a diaphragm (30) is disposed on the sealing member. A fluid port (130) is attached to the base and compressingly engages the diaphragm creating a sealed chamber around the pressure sensor. The sealed chamber is filled with a pressure transmissive fluid (21) such as oil through a fill hole (140) provided in the printed circuit board. This configuration allows the sensor package to be easily assembled with ordinary components and provides a design where all exposed surfaces of the package can be made from a highly non-corrosive material.
