Thermocouple / millivolt gas valves - how do they work ...

· The thermocouple is in the pilot flame which must be lit for gas to enter and if the flame goes out, this low (20 millivolt) signal goes to zero and the main solenoid valve closes cutting the gas supply off, which is a safety measure. The link below is a video of how it works. A thermopile is a bunch of series connected thermocouples that ...

How Does an Infrared Thermometer Work? - Inst Tools

In this post, we will see the working of an infrared thermometer. Nowadays, apart from hand-held thermometer probes, which needed to be fitted around a human arm or mouth, infrared thermometers are widely used in place of that.. Infrared is one of the types of radiation in the electromagnetic spectrum. Other types of radiation are visible light, radio, ultraviolet, gamma, and X-rays.
