NONCONTACT TEMPERATURE SENSOR

摘要

PROBLEM TO BE SOLVED: To provide noncontact temperature sensor which accurately can detect skin temperature of sensing object and also accurately can measure it in a short time. SOLUTION: This noncontact temperature sensor includes a support 21 which has light guiding section for guiding infrared radiation entered from aperture 21a; a resin film 23 arranged on other end aperture on the light guiding section of the above support 21; a lid member 29 with space area for preparing space behind the above resin film 23 formed to be mounted on the support 21; a heat-sensitive element 25 for infrared light detection which is arranged on the space area side of the resin film 23 to sense infrared radiation entered from aperture 21a; and heat-sensitive elements 26 and 27 for temperature compensation which are arranged on surfaces of or inside the support 21 other than inside the space of the space area to detect temperature of the support 21.
