Abstract
A pressure sensor includes a hydraulic path filled with a pressure transfer liquid and a pressure transducer having a pressure sensitive deformation body. The hydraulic path includes a channel which extends from a pressure input opening at least to the deformation body, wherein the pressure input opening is spaced a separation distance from the deformation body, and wherein pressure on the deformation body deviates from pressure at the pressure input opening by the difference of the hydrostatic pressure of the pressure transfer liquid between the pressure input opening and the deformation body. The pressure sensor further includes an inclination sensor for determining at least one inclination value dependent on the inclination of the hydraulic path, and a processing circuit, which is suitable to determine the difference of the hydrostatic pressure of the pressure transfer liquid between the pressure input opening and the deformation body as a function of inclination value, a density value of the pressure transfer liquid and a separation distance.
