Sensor arrangement for a resistance thermometer, resistance thermometer and method for producing a sensor arrangement

摘要

The invention relates to a sensor arrangement (7) for a resistance thermometer, a resistance thermometer and a method for producing a sensor arrangement (7) for a resistance thermometer. In order to provide a solution in which the cover layer (3) has a desired coefficient of expansion which is matched to that of the platinum without the need to carry out complex series of experiments, the cover layer (3) comprises layers (4, 4A, 4B) arranged one above the other. made of a first material and a second material. A resistance thermometer according to the invention comprises a sensor arrangement (7) according to the invention. In a method according to the invention for producing a cover layer (3) for a sensor arrangement (7) for a resistance thermometer, layers (4, 4A, 4B) of a first material and a second material are arranged one above the other.
