Title:
TEMPERATURE MEASURING DEVICE AND HEATER
Document Type and Number:
Japanese Patent JP2002340686
Kind Code:
A
Abstract:
To solve such a problem in conventional temperature measuring device that the temperature of a heat generating object located in a facing position to a bulkhead cannot be precisely measured.
This device is provided with a detection part 3 arranged on one side of the bulkhead 1 formed of an infrared transmitting material to measure the respective intensities in two kinds of wavelength bands of the infrared light from the heat generating object 2 arranged on the other side of the bulkhead 1, and an arithmetic part 4 for arithmetically estimating the temperature of the heating object 2 by use of the ratio of the intensities in the respective wavelength bands measured by the detection part 3.
