The flame detectors are used for the supervision of gas flames, yellow- or blue-burning oil flames and for ignition spark proving. High sensitivity.
-
With this type of flame supervision, the UV radiation emitted by gas or oil flames is used to generate the flame signal.
-
The radiation detector consists of a UV-sensitive cell with 2 electrodes, which ignite when illuminated with radiation in the 190...270 nm range of the spectrum, thereby triggering a current in the flame detector circuit.
-
The UV cell does not respond to glowing firebrick in the combustion chamber, daylight or light from the boiler room illumination.
Die-cast aluminium housing with a 1 in. mounting coupling (D) and a connection facility for cooling air. The housing of this detector has a bayonet fitting which allows it to be secured either directly to the mounting coupling or to the glass holder AGG06. The mounting coupling can be screwed to a viewing tube or to the ball head AGG07. The Pg cable gland can be removed and replaced, if some other detector cable shall be used. | |
