Abstract:
A pressure sensor, having:a housing; a membrane mounted in said housing; a process connection which is connected to said housing and serves to feed to the sensor a medium whose pressure (p) is to be measured by said membrane, said membrane, in operation, undergoing a deflection which depends on the pressure (p) which is to be measured; a gap formed between said housing, said process connection and/or said membrane; a seal which bears directly against said gap, covers said gap, and seals said gap, said seal being clamped between said membrane, said process connection and/or said housing; and 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 defined by said process connection, and is connected fixedly to the latter, and whose second leg has a leg surface which faces away from said first leg, bears in a planar manner against said seal and exerts a spring force on said seal, which spring force acts in the direction of said gap.
