Title:
DEVICE AND METHOD FOR MEASURING TEMPERATURE OF HEAT-TREATED PRODUCT
Document Type and Number:
WIPO Patent Application WO/2012/118016
Kind Code:
A1
Abstract:
This device is provided with: a measurement window (32) which is arranged in a heat treatment furnace (10) and through which a surface (1a) to be measured of a heat-treated product (1) can be observed directly; and a temperature sensor (32) which is arranged outside the measurement window and can measure the surface temperature of the surface (1a) to be measured in a non-contact manner through the measurement window. The temperature sensor (32) has a measurement wavelength range which can be absorbed by water at a low absorption rate (e.g., 1.95-2.5 μm). The measurement window (32) is composed of a window material that exhibits a high transmittance in the above-mentioned measurement wavelength range (e.g., germanium).
