Fireye Type 45UV5 scanners are self-checking, multi-burner flame sensing devices.

When powered by a compatible, self-checking Fireye control, the scanners detect the presence or absence of flames that emit ultraviolet radiation (UV). Typical fossil fuels which emit UV include natural gas, propane, methane, butane, kerosene, light petroleum distillates and diesel fuels. For burners firing steam-atomized oil or pulverized coal, Fireye recommends the use of infrared (IR) scanners. Fireye offers a complete line of infrared scanners best suited for these applications.


  • The UV tube, quartz lens, power transformer and related electronic components are contained in an aluminum enclosure which is sealed with high temperature oil-resistant gaskets.
  • Also included in the Type 45UV5 scanner is an electromagnetic shutter that permits a self-checking circuit within an associated Fireye control to verify that the scanner and signal circuits are producing valid flame presence or absence information.
