WebMar 4, 2024 · To produce electricity, one end must be dipped on a hot surface (e.g.., hot water) while the other end is dipped on something cold. To measure the current flow, a milli-voltmeter can be used. Please check figure A above for details. In understanding how thermocouples work, we must be aware of the variable. WebThermocouples operate on the same principle. A pilot generator creates just a little more power than a thermocouple. A thermocouple will generate about 30 millivolts while a thermopile will create around 350 millivolts. Thermocouples are screwed into a gas valve while pilot generators are wired to the valve. A millivolt is 1/1000 of a volt.
