Detectors 132
Detectors 132 : Particle Detectors: (4.11) Flame Detector: (2) Other Types: (2. 2) Thermocouple Flame Detection: Thermocouples are used extensively for monitoring flame presence in combustion heating systems and gas cookers. They are commonly used as the "flame failure device" to cut off the supply of fuel if the flame fails. This prevents the danger of a large explosive mixture building up, or the hazard of asphyxiation in a confined space due to exclusion of oxygen
