With thermocouple / thermal resistance of double metal thermometer the temperature sensing element is quartz sleeve cross skeleton structure, the skeleton structure of twist to rod type structure. There are many kinds of temperature sensitive materials, which are commonly used in the metal thermal resistance. Industrial measurement of metal thermal resistance materials in addition to platinum wire, there are copper, nickel, iron, iron nickel, tungsten, silver, etc.. Thin film thermal resistance is produced by the method of electron cathode sputtering, which can be used in mass production. In which the skeleton is made of ceramic, and the lead wire is made of platinum and palladium alloy.
