WebThe thermocouple works to shut off the gas supply going into the pilot light when that flame goes out, preventing those explosions from taking place. Prevents gas leaks. Another issue pertaining to the pilot going out is potential gas leaks. Remember, when the flame goes out, there can be gas lingering. WebUsing your flame source such as a lighter, and place the tip of the thermocouple into a flame. As it heats up, attach one lead of the meter to one side of the thermocouple. Then attach the other lead to the end of the thermocouple by the igniter. A working thermocouple will produce a reading of 25 to 30 millimeters.

Metal A Metal B Hot junction Copper Seebeck voltage Copper Screw terminal block Volts Figure 1c—The act of connecting a measurement system made of copper introduces two parasitic thermocouples. Metal A Metal B Junction 1 Copper ... A thermocouple, also known as a "thermoelectrical thermometer", is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction. A thermocouple produces a temperature-dependent voltage as a result of the Seebeck effect, and this voltage can be interpreted to measure temperature. Thermocouples are widely used as temperature sensors.
