Abstract
A pressure sensor for measurements in a chamber of an internal combustion engine, in particular a pressure-measuring glowplug, comprises a housing, a pressure element for picking up a pressure, and a measuring element arranged in the housing downstream of the pressure element in the direction of the pressure and having a sensor element and a diaphragm. This diaphragm is permanently connected at its first end to the pressure element, and at its second end it is directly or indirectly permanently connected to the housing at a connection, with the pressure element being supported on the measuring element via the diaphragm.
