ある。 Plate-shaped resistance temperature sensors consisting of a ceramic plate as a support and a thin metal coating as a resistance layer are known (for example, German Patent No. 828930, German Patent Application No. 2327662, West German Patent Application No. 2327662, West German Patent Application No. Utility Model Registration No. 7541295 and Specification No. 7629727).
The electrical connection between the resistive layer and the connecting edge is obtained by known bonding methods, such as soldering, welding, sintering with conductive paste or gluing. In this case, additional means are required for mechanical unloading of the electrical connection locations. This problem is solved in the case of known implementations of this type of planar resistance temperature detector (West German utility model registration number).
No. 7,629,727), the solution is to pass the lead-in wire through a short insulator and to fuse it together with the insulator to the resistive layer and the ceramic plate by means of a glaze frit. In this case, the glaze frit necessary for welding the insulator to the ceramic plate is simultaneously applied to the resistive layer as a protective coating.
This embodiment has the advantage that the welding of the insulation can be carried out together with the insulation of the resistance path in the same working step. However, this arrangement has the disadvantage that only glazing frits can be used which melt at moderately high temperatures and sufficiently wet the ceramic. This limits the maximum sustained operating temperature of flat resistance thermometers to approximately 500°C, since the resistance path, even if made of precious metal, is often in direct contact with this type of glaze frit. 500℃
This is because it does not provide a stable resistance value at higher temperatures.
