The photo above shows Ralph Fiennes as Amon Goeth, shooting prisoners in the Plaszow camp in the movie Schindler's List. In the background is the quarry where Steven Spielberg built a replica of the Plaszow camp.
A thermocouple is an electrical device consisting of two dissimilar electrical conductors forming electrical junctions at differing temperatures. A thermocouple produces a temperature-dependent voltage as a result of the thermoelectric effect, and this voltage can be interpreted to measure temperature. Thermocouples are a widely used type of temperature sensor. Commercial thermocouples are inexpensive, interchangeable, are supplied with standard connectors, and can measure a wide range of temper
The thermocouple is the co-pilot to the pilot light in electronic heaters. It senses when the flame of the pilot is hot enough to trigger ignition of the natural gas or propane that fuels the burner. In proper working conditions, the thermocouple will open the main gas valve in the pilot housing to ignite the burners.
