Patent ID: 8276457

Claim:
A pressure sensor, comprising: a hydraulic path; a pressure transducer having a pressure sensitive deformation body; an inclination sensor for determining inclination of the hydraulic path; and a processing circuit, wherein: said hydraulic path includes a channel, which extends from a pressure input opening at least to a surface of said deformation body through a solid body or a solid body composite material and which is filled with a pressure transfer liquid; said pressure input opening is spaced a separation distance from said deformation body; the existing pressure on the surface of said deformation body deviates from the pressure presiding at said pressure input opening by the difference of the hydrostatic pressure of the pressure transfer liquid between said pressure input opening and said deformation body; and said processing circuit is suitable to determine the difference of the hydrostatic pressure of the pressure transfer liquid between said pressure input opening and said deformation body as a function of the inclination of the hydraulic path and as a function of a value for the density of the pressure transfer liquid and a value representing the separation distance.
