ABSTRACT:
A pressure measuring device wherein a housing (1) includes a pressure sensor (2) in a pressure chamber (4) and an electronic circuit (14) in a non-pressurized chamber (6). Borings (7) extend between pressure chamber (4) and non-pressurized chamber (6) and accommodate contacts that electrically connect pressure sensor (2) and electronic circuit (14). A pressure membrane (3) cooperates with housing (1) to further define pressure chamber (4) and isolate the device from the fluid system. Pressure chamber (4) is filled with a medium that transmits the system pressure to pressure sensor (2). Pressure sensor (2) measures the pressure and provides an output signal to electronic circuit (14).
