WebA healthy thermopile in an open circuit test will read between 650 to 850 millivolts or somewhere in between. If the open-circuit test reads below 400 millivolts, then the thermopile likely requires service or replacement.2024-02-24 What is the voltage output of a thermopile? Thermopiles use several thermocouples connected in series or parallel. Web1 jan. 2024 · Gsalet said: My concept was to use a 1.5v battery and reduce the voltage to approximately 500mv using a resistor. I think my problem is the amount of current being required by the gas valve coil. Here is what i know : voltage = 500mv resistance for gas valve coil 1.5 - 3.5 ohms. Using a resistor to drop battery voltage is a poor idea because …
Web10 okt. 2024 · Another difference between a thermopile and a thermocouple is that a thermocouple is a metal junction that, when heated by a pilot flame, creates about 25 mv and holds open an electromagnetic valve, allowing gas to pass as long as there is a pilot.
