Explosion-proof differential pressure sensor

A Differenzdruckmessaufnehmer 1 comprises a capsule 2 comprising a ceramic capsule body 20, and a transducer receptacle inside, in which a semiconductor pressure transducer 3 is located, which has a measuring diaphragm body 33 and at least one support body 31, 32, wherein the measuring diaphragm body 33 pressure-tight manner with the at least one supporting body 31, 32 is connected, which has a pressure inlet port 37, 38 with channels 27, 28 each extending from an outer surface of the capsule 2 into the receiving transducer; wherein the pressure inlet port communicates with the first channel, wherein one side of the measuring diaphragm 33 by the pressure inlet port 38 with a pressure can be applied, wherein the carrier body 32 with a joint 42, which surrounds the first pressure inlet opening and the mouth of the first channel 28 in the transducer receptacle, is connected to a wall of the transformer receiving a pressure-tight, and wherein a second side of the measuring diaphragm, is hydraulically isolated from the first side thereof and communicates with the second channel 37th
