Abstract

A measuring sensor for measuring a fluid includes a longitudinally extending housing having first and second ends and having an inlet opening at the first end for the fluid to be measured, and a sensor chip provided in the housing. The sensor chip has a sensor element provided towards the inlet opening and at least one electrically conducting contact provided towards the second end of the housing. The electrically conducting contact is connected to the exterior by a metal jacket lead having an outer metal tube, at least one internal conductor, and a mineral material for electrically insulating the at least one conductor, the outer metal tubing connected in a fluid-tight manner to the second end of the housing. In order to secure the sensor to an installation opening, a collar is welded to an outside of the housing at a selected position corresponding to a selected installation depth of the opening of the housing into the measuring opening. A threaded connector is provided over the collar such that the thread connector mates with a correspondingly threaded element of the measuring opening and secures the sensor in the measuring opening with the selected installation depth by bearing against the collar.
