Patent ID: 8511151

Claim:
A pressure sensor, comprising: a semiconductor pressure measuring transducer having a measuring membrane and a circuit for transducing a pressure dependent deformation of said measuring membrane into an electrical signal; a pressure transfer means having a hydraulic path, which extends through a solid body between a first opening and a second opening, wherein the first opening is sealed by an isolating diaphragm, which is contactable with a pressure to be measured, in order to introduce the pressure to be measured into the hydraulic path, wherein the hydraulic path opens, at the second opening, into a transducer chamber, in which said pressure measuring transducer is arranged and which is sealed by said measuring membrane of said pressure measuring transducer, wherein the hydraulic path contains a transfer liquid; a filling element, which is arranged in said transducer chamber, in order to fill hollow spaces between metal walls of said transducer chamber and said semiconductor pressure measuring transducer; and an insulator plate, which is arranged in said transducer chamber between said measuring membrane and a wall of the transducer chamber lying opposite said measuring membrane, wherein: said insulator plate is affixed to said filling element or is embodied as one piece with said filling element.
