Abstract
A pressure sensor has a movable diaphragm stretched directly between the annular pressing surfaces of two housing parts, and an electrical measuring device. In an area that is located radially outward as viewed from the pressing surfaces, the diaphragm has a sealing ring that abuts both housing parts. As a result, transverse vibrations of the diaphragm are reliably supported.
