Flame sensor vs thermocouple
WebJoseph Wu ABSTRACT Thermocouples are common temperature sensors used in a wide variety of commercial and industrial applications. While slightly less accurate than resistance temperature detectors (RTDs), thermocouples cover a wide temperature range, are self-powered, and have a fast response time.

WebFeb 17, 2006 · Its purpose is to provide the flame needed to light the gas coming out of the main burner. When the furnace "turns on", a valve releases gas into the burner and the pilot light ignites that gas. The way that a pilot light is created is also simple. It is made by allowing a small amount of gas to come from the gas pipe through a small tube. WebApr 11, 2024 · Flame sensing is an important part of combustion control as it prevents fuel flow in the absence of ignition. Depending on the fuel used, and the consequences of …
