Pressure Sensor

Abstract

A pressure sensor is described and shown for determining the pressure of a fluid medium in a volume limited by a wall. The pressure sensor includes at least one sensor element, a sensor housing, at least one first pressure compensation channel and a protective cap. The sensor element is arranged in the sensor housing. The protective cap is connected to the sensor housing on the medium side. The sensor element is connected to the medium via the at least one first pressure compensation channel during operation. The at least one first pressure compensation channel is at least partially introduced as a recess in the protective cap. The at least one first pressure compensation channel is geometrically designed in such a way that, in order to relieve the sensor element, pressure peaks are damped by deflection and/or by increased wall friction of the medium.
