Abstract
A pressure sensor is provided with a carrier (), which in an inner region includes a membrane () on which at least one first measurement element (R) for detecting a pressure impingement of the membrane () is arranged. Additionally, at least one second measurement element (R) for detecting a pressure impingement of the membrane () is arranged on the membrane. The first measurement element (R) and the second measurement element (R) are arranged distanced differently far from the edge of the membrane. The output signals of the first and the second measurement element (R, R) are evaluated together in a manner such that the two measurement elements (R, R) detect a differential pressure acting on the membrane (), and thereby compensate the influence of the system pressure acting on both sides of the membrane ().
