Flame Scanners


Spectrum UV Flame Scanning System

The Spectrum UV Flame Scanner family has been specifically designed to offer reliable flame scanning and discrimination for propane or natural gas fired, multiple-burner, boilers. A compact design, which employs ultraviolet (UV) tube technology, is also well suited for dual fuel (oil/gas) single burner package boilers.

The UV 5 is available in two models;
• Electronic self-test
• Mechanical shutter test

Both models use the same electronic amplifier. The UV5 Scanner Head responds to electro-magnetic radiation in the ultraviolet spectrum and produces a series of pulses proportional to flame intensity. The amplifier contains the decoding electronics, which converts the variable frequency to a voltage level. This is translated into a flame level, which is presented on a bargraph located on the face of the module. When that level rises above a set point, the flame contact is energized.
