Title: Infrared temperature sensor
Inventor: FUKAZAWA TAKESUKE
IPC: G01J5/10
Filed: 2003-05-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide an infrared temperature sensor which has high measurement accuracy and which can be miniaturized.  <P>SOLUTION: In the infrared temperature sensor 1, a first resin film 8 for holding a detection thermistor 9 receives and absorbs an infrared ray emitted from an object to be measured through an aperture 6a formed in a housing 2. A second resin film 11 for holding a compensation thermistor 12 is completely shielded by a partition wall 3 from the infrared ray emitted from the object to be measured, and receives and absorbs the infrared ray emitted from the housing 2 or the partition wall 3. Accordingly, because the second resin film 11 is securely prevented from being irradiated with the infrared ray emitted from the object to be measured, the temperature of the object to be measured can be precisely measured. Further, because the resin films 8 and 11 are arranged so as to be disposed opposite each other in the housing 2, the infrared temperature sensor 1 can be miniaturized.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
