Abstract

A pressure sensor is provided having a housing, a process connection which is connected to the housing and serves to feed a medium whose pressure (p) is to be measured to a membrane which his arranged in the housing, said membrane, in operation, undergoing a deflection which depends on the pressure (p) which is to be measured, which pressure sensor can have a seal made of a chemically highly resistant material and in which the membrane can consist either of ceramic or metal, which pressure sensor has a seal which seals a gap found between the housing and the process connection and/or the membrane, bears directly against the gap and covers the gap, and which is clamped between the housing and the membrane, and which pressure sensor has a spring which is two-legged in cross section, whose first and second legs enclose an acute angle, whose first leg has a leg surface which faces away from the second leg, rests on a supporting surface and is connected fixedly to the latter, and whose second leg has a leg surface which faces away from the first leg, bears in a planar manner against the seal and exerts a spring force on the seal, which spring force acts in the direction of the gap.
