Flame detection signal from ultraviolet detector.
Flame detector has three independent probe, is used to detect the wavelength for 180 -
260 ultraviolet (uv) radiation.
When one of the flame radiation effect to probe the cathode, the electron beam radiation.
Electron beam effect to probe ionized gas, which emit more electrons, to produce an avalanche conditions.
More electrons released, between the cathode and anode to produce a transient electron flow.
The instantaneous electron flow (
And ultraviolet radiation intensity is proportional to the rate of recurrence.
The frequency of the pulse in detector is replaced with voltage and transmitted to the controller.
