Abstract

PURPOSE: To obtain a thermometer of good prompt responsiveness of temperature detection and easy mounting and dismounting by filling the spacing between the guide tube and sheath form temperature detector with powder material of high melting point and good heat conductivity and making use of a metal of good heat conductivity as sheath material.
CONSTITUTION: The thermometer is constituted by a well 1 which contains a sheath form thermocouple 2 and metal powder 3 filled in the spacing between both. The end 6 of the heat sensing part 4 of the thermocouple 2 is in close contact with the inside surface of the well 1 and the powder 3 is filled until the temperature sensing part 4 of the thermocouple 2 is buried. The powder 3 may not be metal powder if it is of high melting point and good heat conductivity. Since the heat from the well 1 is rapidly transmitted to the heat sensing part 4 of the thermocouple 2 by the powder 3, the response speed equal to that of liquid metal may be obtained; in addition, the metal well not solidify by the effect of ambient temperature because it is powdery, which makes mounting and dismounting of the thermocouple easy. A metal of good heat conductivity is used for the sheath form temperature sensing part 4 in order to enhance the prompt responsiveness of detection. Hence, the prompt responsiveness of temperature detection may be improved and interchangeability improved.
