Abstract

PURPOSE: To prevent the occurrence of contact defect and improve reliability by letting the measured body as one pole and letting a temperature sensing element to contact as other pole to the surface of the measuring object.
CONSTITUTION: Films 32, 81 of the same nature of small effect of oxidation are applied on the respective contact portions of a copper plate 1 and constantan rod 3. Namely, the film 32 of 20W30μ in thickness by nickel or chrome plating is applied to the end of the constantan rod 3 and the similar film 81 on the hole bottom 8 of an insertion hole 7 as well. Both the films 32, 81 are pressed to each other to constitute a contact type thermocouple by way of the films 32, 81, by which the contact defect by the oxide films at the hole bottom 8 of the insertion hole 7 of the copper plate 1 and the end of the constantan rod 3, these becoming the both poles of the thermocouple, may be prevented.
