Thermopile detectors - Hamamatsu

Thermopile detectors are thermal detectors that utilize the Seebeck effect in which a thermal electromotive force is generated in proportion to the incident infrared light energy. Thermopile detectors themselves have no wavelength dependence. Sensitivity spectra are selected by attaching various window materials, and used for applications such

How Do Thermoelectrics Work? - Power Practical

Thermoelectric power is the conversion of a temperature differential directly into electrical power. Thermoelectric power results primarily from two physical effects: the Seebeck effect, and Peltier effect. The Seebeck effect is named after Thomas J. Seebeck, who first discovered the phenomenon in 1821. Seebeck noticed that when a loop ...

Thermoelectric effect – Seedbeck, Peltier, Thomson | Blog ...

2014-04-18· The thermoelectric effect is the direct conversion of temperature differences to electric voltage and vice versa. A thermoelectric device creates voltage when there is a different temperature on each side. Conversely, when a voltage is applied to it, it creates a temperature difference. At the atomic scale, an applied temperature gradient causes charge carriers in…

Thermopile vs. Thermocouple Fireplace | Hunker

Thermocouples first appeared after the discovery of the thermoelectric effect by Thomas Johann Seedbeck in 1821. Seedbeck discovered that a pair of junctions between two wires made of different metals creates voltage equal to the temperature difference between the junctions. Basically, a thermocouple consists of two wires made of different metals joined in two places. Heat enters at one …

Thermoelectric effect - New World Encyclopedia

The thermoelectric effect is a phenomenon by which a temperature difference is directly converted to electric voltage and vice versa. On the measurement-scale of everyday life, a thermoelectric device creates a voltage when there is a different temperature on each side. Conversely, when a voltage is applied to it, it creates a temperature difference.
