Introduction

This sensor features a high temperature and high
sensitivity ultraviolet (UV) tube for monitoring gas or oil
flames in applications that cycle on and off frequently. The
scanner is UL listed for USA and Canada, and FM
approved when used with Eclipse model 5600 and VF56
series Veri-Flame, model 6000 Multi-Flame, model 6500
Bi-Flame, or series 7000 Peek-A-Flame. This product is
also in conformance with the "CE Mark" Directives when
used with the model VF56 Veri-Flame CE as listed in its
Instruction Manual 818-2. It comes with a 6 ft flexible
metal cable and an insulated coupling.

The UV tube is made of quartz and is filled with a gas that
surrounds two electrodes. These electrodes are
energized continuously by a high voltage. The gas acts as
an insulator in the absence of UV radiation. Combustion
produces UV radiation to ionize the gas and causes
current pulses to flow between the electrodes. These
current pulses result in a flame signal which is transmitted
to the amplifier in the control, where it is processed to
energize and hold in the flame relay.
