AAS-930-164B Thermopile IR Sensor Applications
Features :
The thermopile has some unique properties not of-fered by other detectors:
Product Introduction :
A thermopile is a serially-interconnected array of thermocouples, each of which consists of two dissimilar materials with a
large thermoelectric power and opposite polarities. The thermocouples are placed across the hot and cold regions of a structure
and the hot junctions are thermally isolated from the cold junctions. The cold junctions are typically placed on the silicon substrate
to provide effective heat sink. In the hot regions, there is a black body for absorbing the infrared, which raises the temperature
according to the intensity of the incident infrared. These thermopiles employ two different thermoelectric materials which are
placed on a thin diaphragm having a low thermal conductance and capacitance.
Package :
Our thermopile detector is packaged with silicon filter and thermistor as shown below. We are supplying TO-5 package and
TO-46 package as the standard type , but on request, other package types are also available.
