Abstract
A construction concept for high-pressure sensors is provided, which enables simple and economical production of reliable high-pressure sensors even for pressure ranges above 2200 bar. A high-pressure sensor of this kind encompasses a sensor element for pressure sensing and a connector piece for coupling the sensor element to a system to be measured. A diaphragm is embodied in the base element of the sensor element, and a pressure conduit is embodied in the base element of the connector piece. The sensor element is mounted on the connector piece so that the pressure to be measured is able to act upon the diaphragm via the pressure conduit. Firstly the base element of the sensor element is mounted on the base element of the connector piece, a full-area connection being generated between the mounting surfaces of the two base elements. Only thereafter is the pressure conduit configured in the connector piece, and the diaphragm of the sensor element exposed.
