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.

Abstract: A pressure-measuring device is situated in a chamber of an internal combustion engine. The pressure-measuring device has a housing, a force-transmitting element that protrudes partly from the housing at a chamber-side opening of the housing, and a pressure sensor that is situated in an interior space of the housing. The pressure sensor stands in effective connection to the force-transmitting element. In addition, a diaphragm is provided that seals the interior space of the housing, in which the pressure sensor is situated, against the chamber-side opening. The diaphragm, which is preferably fashioned as a metal diaphragm, has a force-transmitting segment that is oriented in an axial direction of the force-transmitting element. Moreover, the pressure sensor stands in effective connection with the force-transmitting element via the force-transmitting segment of the diaphragm. In this way, there takes place at least a partial compensation of thermally caused changes in length of the diaphragm, caused for example by hot combustion gases, and resulting in periodic impairments of the pressure measurement made by the pressure sensor.

Abstract: A pressure-measuring device is used for placing in a chamber of an internal combustion engine. The pressure-measuring device has a housing, a force-transmitting element in operative connection with a pressure sensor, and a centering element. The pressure sensor is placed, together with contact plates, on a centering section of the centering element, thereby making it possible to position the pressure sensor and the contact plates within the housing of the pressure-measuring device. The assembly of the pressure-measuring device is thereby facilitated, and a preassembly is possibly allowed.
