Fireye 45UV5-1105 Self-check flame scanner is used to detect ultraviolet emissions from fossil fuel flames such as natural gas, coke oven gas, propane, methane, butane, kerosene, light petroleum distillates and diesel fuels.
Fireye 45UV5-1105 self-check flame scanner is used with classic P-Series Flame safeguard control to provide flame safeguard and monitoring systems for supervised manual, semi-automatic and fully automatic single burner boilers, process ovens and heaters.
The 45UV5-1105 scanner uses 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.”
