45RM4 Series Scanner

The Fireye^® Type 45RM4 flame scanners are self-checking, flame sensing devices. They consist of a lens, photodetector, and a solid-state, frequency tuned circuit contained in a die-cast aluminum housing.

When powered by a compatible, self-checking Fireye flame safeguard control, the scanner detects the presence and absence of flames having certain characteristics.

The 45RM4 has a 16-position rotary selector to select the ideal flame “flicker” frequency. This is effective in detecting and discriminating Flame ON and Flame OFF conditions on installations where low frequency emissions predominate (pulverized coal, lo-nox, etc.), as well as mid-range frequency applications (natural gas). This allows type 45RM4 scanners to discriminate between the targeted flame and background flame for a wide range of applications and fuels.
