Abstract:
In a process for manufacturing a sensor arrangement for temperature measurement with a temperature-sensitive measuring resistance element, comprising the steps of:providing the measuring resistance element, the element comprising a thin metal film as a resistance layer and contact surfaces on a ceramic substrate,covering the resistance layer with an electrically insulating protective layer,connecting the contact surfaces in an electrically conducting and directly mechanically fast manner with high temperature-resistant conductor paths which are electrically insulated from each other on a high temperature-resistant carrier element comprising an electrically insulating material,bonding the measuring resistance element at one end of the carrier element, and arranging the contact surfaces on an opposite end of the carrier element facing away from the measuring resistance element for connection with a contact clip, plug or cable, the improvement comprising:applying at least a first and a second thick film conducting paste by a double application to at least one of the contact surfaces (3, 4) of the carrier element (2) and the measuring resistance element (1) before placing the measuring resistance element (1) on the high temperature-resistant carrier element (2), wherein only the first thick film conducting paste for a first application to the at least one of the contact surfaces of the measuring resistance element (1) and the carrier element (2) contains a fritted glass component, thenplacing the measuring resistance element (1) on the carrier element (2) with its contact surfaces, and subsequentlyfiring the carrier element (2) at a temperature range of 1000.degree. C. to 1350.degree. C. to thereby bond and fasten the measuring resistance element (1) to the carrier element.
