Pressure sensor
First Claim
1. A pressure sensor having a diaphragm seal (3, 45) with a separating diaphragm (7, 53), on which a pressure (P) to be measured acts, and a ceramic measuring cell (9, 57) , connected exclusively by inorganic materials to the diaphragm seal (3, 45), in which the separating diaphragm (7, 53) and all further sensor components coming into contact during measurement with a medium of which the pressure (P) is to be measured are metallic.
