Thermopile IR Sensors


Amphenol Advanced Sensors' thermometrics thermopile consists of serially-interconnected array of thermocouples

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.

Amphenol Advanced Sensors’ thermopile ZTP series of infrared (IR) sensors are used for non-contact temperature measurement in various applications like microwave ovens, cooktops, air conditioners and thermometers.
