Patent ID: 8726735

Claim:
A differential pressure transmitter, comprising: a differential pressure sensor, which has a signal output in order to emit a signal that depends on a measured difference between a first medium pressure and a second medium pressure, or that represents this difference; a first process connection flange and a second process connection flange, wherein said differential pressure sensor is fixed between said first process connection flange and said second process connection flange and a first and a second seal, wherein said seals are each arranged between one of said process connection flanges and said differential pressure sensor, wherein said differential pressure sensor can be exposed to a first medium pressure via aid first process connection flange and a second medium pressure via said second process connection flange; and a housing, which contains an electronic evaluation circuit, said housing has an input opening via which the signal output of said differential pressure sensor is connected to a signal input of said evaluation circuit, wherein: said housing has at least one extension which extends between said first and second process connection flange; said at least one extension is fixed between said flanges in a parallel connection relative to said differential pressure sensor in such a way that said housing is held by said fixed extension, said differential pressure sensor has a sensor neck, which extends from a lateral area of said differential pressure sensor into said input opening of said housing; an open ring junction is formed between said sensor neck and said input opening of said housing; and the differential pressure transmitter further has a guide sleeve, which is arranged in said open ring junction.
