The Fireye UV Self Checking 45UV5-1009 Scanner detects ultraviolet emissions from fossil fuel flames such as natural gas. The scanner detects UV emissions from coke oven gas, propane, methane, butane, kerosene, light petroleum distillates and diesel fuels.
These 45UV5 models are used only with the Flame-Monitor, BurnerLogix, D-Series, FlameWorx, MicroM and some P-Series Fireye control models. It provides flame safeguard and monitoring systems for supervised manual, semi-automatic and fully automatic single burner boilers, process ovens and heaters.
The 45UV5 scanners use a UV-eye detector. This detector is a sealed, gas filled, UV-sensitive tube containing two electrodes connected to a source of AC voltage. When UV radiation of sufficient energy falls upon the electrodes, electrons are released and the inter-electrode gas becomes conductive, resulting in an electric current flow from one electrode to the other. The current flow starts and ends abruptly and is known as an “avalanche.”
