Flame Detector which contains an ultraviolet photo tube
that responds to radiation in the 185 to 260 nano meter region when radiation
from a flame strikes the cathode plate within a UV detector tube, electrons are
ejected from the cathode plate. These electrons are accelerated towards the
positively charged anode of the tube. They collide with molecules of an
ionization gas, with which the tube is filled. This emits more electrons and
produces an avalanche condition. More
electrons are released which creates a momentary electron flow from the
cathode to the anode. This momentary current (pulse) recurs at a rate
proportional to the intensity of the UV
radiation. This output converted to standard mA output.

I am agree with you that your flame detectors instruments must be in good condition. In any case of emergency it may minimize the risk factors. I found det-tronics flame detection is absolutely according to world class standard.

The benefits of having a fire alarm system installed in your home or commercial property are clear. A fire can cause irreversible and extensive damage to your home and it is just not worth taking the risk. Luckily a fire can be prevented using alarms, detectors and other various systems.

Thnq for sharing Good Info HOUSEHOLD GAS ALARM can also be called gas alarm, which is a kind of small gas safety products suitable for family use
