Spectrex 20/20ML Mini UV/IR Flame Detector

Status: Emerson lists the Spectrex 20/20ML Mini UV/IR flame detector as obsolete. For a replacement, send us the model code from the installed unit and we will check the current Spectrex and Rosemount options with Emerson.

The SharpEye Mini-UV/IR Flame Detector (20/20ML) is a compact style detector featuring excellent detection sensitivity combined with enhanced immunity to false arms.

This model is designed to detect hydrocarbon-based fuel fires, hydroxy and hydrogen fires, as well as metal and inorganic fires.

The UV/IR flame detector senses energy in the short wave section of both the ultraviolet and infrared portions of the electromagnetic spectrum.

The UV sensor incorporates a special logic circuit that helps prevent false alarms caused by solar radiation. The IR sensor is sensitive to radiation over the range of 2.5 to 3.0 microns. The signals from both sensors are analyzed for frequency, intensity and duration. Simultaneous matching of radiant energy in both the UV and IR sensors triggers an alarm signal.
