MEDIA COMPATIBLE PACKAGES FOR PRESSURE SENSING DEVICES

摘要

A pressure sensing device (100) for measuring pressure of a fluid comprising a housing (105) having an opening, a circuit board (115) located in the opening, and a pressure sensor (18) electrically coupled to the circuit board (115). The device further includes a sealing member (45) extending around the pressure sensor and a diaphragm (30) located between the sealing member (45) and the housing such that the circuit board (115), the sealing member (45) and the diaphragm (30) form a chamber (125). The chamber (125) is filled with a pressure transmissive fluid and the pressure sensor (18) is located in the chamber (125) such that pressure that is applied to the diaphragm (30) is substantially transmitted to the pressure sensor (18) via the pressure transmissive fluid. The device (100) further includes a closing member (170) that engages the circuit board (115) and retains the circuit board in the opening.
