Abstract

A pressure measuring device suitable for disposition in a chamber of an internal combustion engine. The pressure measuring device has a housing, a force transmitting element that is effectively connected to a pressure sensor, and a sensor cage that surrounds the pressure sensor. The sensor cage is connected to the housing by a circumferential weld seam only at one connection segment of the housing. In this way, it is possible to achieve a defined pre-tensioning of a metal diaphragm that is connected on the one hand to the sensor cage and on the other hand to the force transmitting element.
