Embodiment Construction
[0041] Referring to FIGS. 1 and 2 , a thermopile array device 80 as a thermopile device according to the present invention as shown in FIG. 2 mainly includes an array of thermopile sensors 10 schematically illustrated in FIG. 1 . Each thermopile sensor 10 is adapted to inspect or monitor a monitoring point 52 forming part of the overall monitoring area of the device 80 .
[0042] When referring to an element X of a thermopile sensor as shown in FIG. 1 of the thermopile sensor array shown in FIG. Number X-i. Here, i is an integer identifying a particular thermopile sensor 10-i in the sensor array, i can assume any value from 1 to n, where n represents the number of thermopiles contained in the array.
[0043] As shown in FIG. 1, in one embodiment of the present invention, a thermopile sensor 10 includes a first source element 14 thermally coupled to a first contact 15 of a downsized thermocouple 12 and a first source element 14 thermally coupled to the thermocouple 12. The ...
