Title: Temperature transmission device
Inventor: SHINOHARA MITSUHIRO
IPC: F23M11/04
Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To perform an accurate temperature measurement by a method wherein a thermocoule and an output cable are approached to each other. SOLUTION: A temperature of a reference contact point 6 is measured by a reference contact point temperature sensor 7 fixed near the reference contact point 6, and a temperature of the temperature measuring contact point 1 is measured in reference to a thermo-electromotive force generated in reference to this measured temperature. Then, the obtained signal is converted by a converter 5 into a signal such as a DC current or the like and outputted to an external side through an output cable 9. At this time, since the thermocouple 2 and the output cable 9 are approached from each other, at a location where the thermocouple 2 and the output cable 9 are adjacent to each other, each of the temperatures becomes approximately the same value through a heat exchanging operation, resulting in that a temperature gradient at the converter 5 can be reduced.  With such an arrangement as above, it is possible to reduce an error in accommodation of the reference contact point 6 due to the temperature gradient at the converter 5. Accordingly, it is possible to perform an accurate measurement of temperature.
