WebMake thermocouples from other metals (like iron or plain steel wire, copper, or aluminum) and compare the magnitude of the effect for the different combinations. Note that the effects might be small depending on the metals used. See if you can compute the Seebeck coefficient from the metals used. 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.
