  • Temperature sensor and process for its production
    Patent number: 5202665
    Abstract: The invention relates to a temperature sensor with platinum of temperature-sensitive material, and a process for the production of such a temperature sensor. The problem of the invention is to provide a miniaturized temperature sensor as small as possible which can be used at temperatures of 600.degree. C. to over 1,000.degree. C. For solution, the invention proposes a temperature sensor in which the layer contains finely divided metal platinum in oxide ceramic. Production takes place by mixing together platinum powder, oxide and binder, and after supplying the layer on the support substratum, tempering with this latter.
