1.Measurement principle of Flue dust transmittance detector
The detection light traverses the flue, and the single optical path measurement system consists of a transmitter and a receiver. A high-brightness LED light source is installed in the transmitter. The beam it emits passes through the diffuser and then through the flue. It is projected onto the focusing lens in the receiver and is focused on the measurement detector; the other part is directly focused on the reference detector. . The light transmittance or light opacity value can be obtained by calculating the ratio of the signal intensities obtained on the two detectors, from which the light transmittance (or light opacity) and dust concentration values can be obtained.
2. Main features of Flue dust transmittance detector
