WebWhen heat is applied to a thermocouple or thermopile they produce a very small amount of electrical current. That keeps a solenoid in the gas valve open via a pilot light that stays lit 24/7. If the fire or pilot light ever goes … WebA thermopile is a stack of two different conducting materials. It generates a voltage in response to a temperature difference between the ‘hot’ and the ‘cold’ side of the stack. This phenomenon is known as the ‘thermoelectric effect’, expressed by the different Seebeck coefficients of the two materials.

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. WebThe thermopile is nothing but thermocouples connected in series or parallel. When the infrared radiation falls on the thermopile surface, it gets absorbed and converts into heat. Voltage output is produced in proportion to the incident infrared energy. The detector uses this output to determine the temperature, which gets displayed on the screen.
