Title:
NON-CONTACT TEMPERATURE SENSOR
Document Type and Number:
WIPO Patent Application WO/2011/083593
Kind Code:
A1
Abstract:
Disclosed is a non-contact temperature sensor which comprises a casing (14) having a top panel portion (34) constituting a shielding surface (34a) that shields infrared rays and a light guiding portion (40) that is formed by opening a part of the top panel portion (34) and that guides infrared rays into the casing. The non-contact temperature sensor further comprises a flexible printed circuit board (12) having a thermo-sensitive element (20a) for infrared detection and a thermo-sensitive element (20b) for temperature compensation and a sensitivity adjusting member (18) having an infrared shielding portion (18b) and capable of adjusting the position of the infrared shielding portion (18b) with respect to that of the thermo-sensitive element (20a) for infrared detection. The infrared shielding portion (18b) is positioned so as to face the thermo-sensitive element (20a) for infrared detection within an inner region of an open region (42) of the light guiding portion (40) except for an end portion in the moving directions of the sensitivity adjusting member (18). The sensitivity of the thermo-sensitive element (20a) for infrared detection can be adjusted by adjusting the position of the infrared shielding portion (18b) while the viewing angle of the thermo-sensitive element (20a) for infrared detection and the open area of the open region (42) are fixed.
