Title:
高速応答性熱電対
Document Type and Number:
Japanese Patent JP4437592
Kind Code:
B2
Abstract:
A thermocouple-type temperature-detecting device excellent in the temperature measurement responsiveness constituted of an outer protective pipe 1 and an inner protective pipe 2, the outer protective pipe 1 is formed in a laminated layer structure of a 2nd layer 10 made of a ceramic containing molten metal-repelling BN and a 1st layer 11 made of a ceramic, the inner protective pipe 2 is formed of a front protective pipe 3 made of a ceramic having a good heat conductivity and a heat-shielding rear protective pipe 4 extending into the outer protective pipe 1 through an air layer 17, furthermore, the head portion 5 of the front protective pipe 3 is projected from the outer protective pipe 1, and a temperature-sensitive portion 20 of a thermocouple is disposed in the inside of the head portion 5.
