A thermopile is an electronic device that converts thermal energy into electrical energy. It is composed of several thermocouples connected usually in series or, less commonly, in parallel. Such a device works on the principle of the thermoelectric effect, i.e., generating a voltage when its dissimilar metals (thermocouples) are exposed to a temperature difference.
Capital Semiconductor’s thermopile sensors can be operated at temperatures between -20 and +120°C (-20 to 180°C for HTS-HT) and are normally equipped with a thermistor reference to determine the sensors housing temperature which normally is equal to ambient temperature. The Sensors are available in standard TO-39 packages, TO-46 packages and Micro TO packages.
