ABSTRACT:
A pressure or pressure difference measuring instrument with a central part which has separating seal diaphragms at its end faces and which contains a pressure-sensing device is disclosed. In order to arrange the pressure-sensing device in the central part, the central part is provided in a circumferential area between the end faces with a pot-like recess into which a carrier for the pressure sensing device is inserted. The carrier has a cross hole which changes into a pressure-transmitting canal in the central part in such a position that due to the carrier being welded to the central part, there is produced at the same time a seal in the area of the point of transition from the cross hole to the pressure transmitting canal.
