Abstract

A pressure sensor has a measuring cell, a measuring cell mount and an electronic sensor system connected to the measuring cell. The pressure sensor is designed as a modular unit in which the electronic sensor system and its electric connections are protected against moisture and mechanical loads, in which the electronic sensor system is embedded in a protective cushion, and in which the protective cushion is surrounded by an encapsulation.
