Measurement principle

If light passes through a flue gas duct or a dust exhaust duct, the higher the dust den

sity the greater the attenuation. The attenuation of the light results from both absorp

tion and scattering, referred to in combination as

Extinction [

}

195]

E extinction. The

extinction process is characterised by the light intensity diminishing exponentially as

the length of the path travelled by the beam, according to the Lambert-Beer Law.
