Patent ID: 6871546

Claim:
A pressure senior module, comprised at least of a pressure sensor chip for detecting a pressure, wherein said pressure sensor chip is connected to a pressure fitting that conducts the pressure to the pressure sensor chip, wherein the pressure fitting ( 19 ) has an adapter ( 21 ) connected to it, wherein said adapter receives the pressure and transmits the pressure to the pressure sensor chip ( 7 ) by means of the pressure fitting ( 19 ), wherein said adapter protects the pressure sensor chip ( 7 ) from mediums that could damage the pressure sensor chip ( 7 ), wherein the pressure sensor module ( 1 ) is disposed in an Insertion opening ( 69 ) of a wall ( 53 ), wherein the pressure sensor module ( 1 ) has a separating membrane ( 29 ), wherein the wall ( 53 ) encloses a medium( 59 ), wherein said medium is in contact with the separating membrane ( 9 ), and wherein the pressure sensor module ( 1 ) can be moved partway out from the insertion opening ( 69 ) when the medium ( 59 ) freezes and expands.
