WebHow Infrared Thermometers Work. Infrared light works like visible light--it can be focused, reflected or absorbed. Infrared thermometers usually use a lens to focus infrared light from one object onto a detector called a thermopile. The thermopile absorbs the infrared radiation and turns it into heat. The more infrared energy, the hotter the ... WebDec 26, 2024 · A thermopile is simply multiple thermocouples. Some millivolt systems will also use a thermocouple for flame safety. Under load, a thermopile should operate at no less than 190MV. Please refer to the wiring diagram while reading the information below. You're going to feed 120v to the transformer.

WebThe thermopile is nothing but thermocouples connected in series or parallel. When the infrared radiation falls on the thermopile surface, it gets absorbed and converts into heat. Voltage output is produced in proportion to the incident infrared energy. The detector uses this output to determine the temperature, which gets displayed on the screen. WebMay 5, 2024 · As you may have guessed already, a thermopile creates only a minimal voltage. So, the multimeter should be precise enough to record that. The first step is removing the thermocouple from the water heater. You should be able to do this by following the safety instructions provided by the manufacturer.
