ABSTRACT:
In the case of a pressure sensor (1) a measuring cell (4) is fixed together with a retaining body (9) in a housing (2) of the pressure sensor. For this purpose, the housing (2) has a constriction (15) encircling it on the outside. A contact base (11), which is placed at the top onto the retaining body (9), is fixed by means of an inwardly bent section (18) of the housing (2), with the result that the pressure sensor (1) is closed in a sealed manner. The fixing of the retaining body (9) by means of the constriction (15) means that the pressure sensor (1) is also suitable for particularly high pressures with the risk that the retaining body (9) could slip in the housing (2) due to the pressure acting on the measuring cell (4) being excluded.
