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.
The die-cast alloy flame detector head is sealed with a quartz-glass lens. In addition to the plug-in UV cell, the head contains a rotating shutter which – for the purpose of continuous testing of the UV cell’s striking and extinction voltage performance – interrupts the UV radiation at the rate of 3 times per second. The shutter is driven by a synchronous motor which is suited for continuous operation.
The flame detector is attached to the viewing tube by means of a flanged mounting coupling which has a 1 in. internal thread. A 3/8 in. tapping on the side of the coupling enables a cooling air conduit to be connected, provided that dry, dust- and oil-free compressed air is available.
