A thermopile is an electronic device that converts thermal energy into electrical energy. [1] 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 ...
The black coating on the thermopile sensor absorbs the radiation that is converted to heat. The heat flows through the sensor to the sensor housing and from the housing to the cooling water. The thermopile sensor generates a voltage output signal that is proportional to the heat flux.
Special test sets are made to confirm the valve let-go and holding currents, because an ordinary milliammeter cannot be used as it introduces more resistance than the gas valve coil. Apart from testing the open circuit voltage of the thermocouple, and the near short-circuit DC continuity through the thermocouple gas valve coil, the easiest non ...

A thermoelectric generator (TEG), also called a Seebeck generator, is a solid state device that converts heat (driven by temperature differences) directly into electrical energy through a phenomenon called the Seebeck effect [1] (a form of thermoelectric effect).
In this case the sensor is mounted on a water-cooled body. Such sensors are used in fire resistance testing to put the fire to which samples are exposed to the right intensity level. There are various examples of sensors that internally use heat flux sensors examples are laser power meters, pyranometers, etc.
The Seebeck coefficient (also known as thermopower, [1] thermoelectric power, and thermoelectric sensitivity) of a material is a measure of the magnitude of an induced thermoelectric voltage in response to a temperature difference across that material, as induced by the Seebeck effect. [2]
