Title:
QUICK-RESPONSE THERMOCOUPLE FOR HIGH-SPEED FLUID
Document Type and Number:
WIPO Patent Application WO/2009/057728
Kind Code:
A1
Abstract:
This aims to provide a thermocouple of a quick response, which does not receive
a mechanical damage such as a fold or bend even if it is used in a high-speed fluid.
A quick-response thermocouple for a high-speed fluid is constituted such that
a sheathed thermocouple of a small external diameter, in which a plus-side thermocouple
filament and a minus-side thermocouple filament are contained in a metal sheath
while interposing powder of an inorganic insulating material and in which the
plus-side thermocouple filament and the minus-side thermocouple filament
are joined to each other at their tips to form a temperature measuring point, is
so inserted into a protective tube of a large external diameter as to expose its
tip. The exposed portion of the sheathed thermocouple from the protective tube
is inserted into a protective cylinder including a plurality of through windows
and a bottom cover having a hole, through which the sheathed thermocouple is inserted,
in its tip side, so that the tip of the sheathed thermocouple is shortly exposed
from the protective cylinder bottom cover, and so that the protective cylinder
bottom cover and the sheathed thermocouple, and the protective cylinder and
the lower portion of the protective tube are welded to each other.
