Product Overview
e UV-4 is exceptional at sensing ultraviolet radiation that is emitted
from the combustion of gas or light oil. e spectral radiation of these fuels
in the ultraviolet range is significantly greater than other fuels, and allows the
UV-4 to positively sense and discriminate a targeted flame. e UV-4 can be
applied to both wall-fired and tilting-tangential type burners. e UV-4 is used
in conjunction with the Forney IDD 9000 or DR-6101E Amplifier and is
connected by a four conductor, shielded prefabricated cable.
e UV-4 assembly is available with two different base configurations:
“front mount” for wall burners and “fiber optic mount” for tilting type burners
or where special sighting is required. e UV-4 is self checking for use as a main
flame detector or Class 1 or 2 igniter detector. e UV-4 uses a high quality
photoionization tube sensor with a rugged aluminum mechanical shutter.
Quick disconnects available for ease of
replacement.
