LDM-100(D) is an in-situ dust analyzer based on the laser backscattering principle, which is mainly used to measure smoke and dust within the conventional ranges.
LDM-100(D) is an in-situ dust analyzer based on the laser backscattering principle, which is mainly used to measure smoke and dust within the conventional ranges.
Principe
This monitor adopts the laser backscattering principle to measure the dust concentration. The embedded laser signasource traverses the flue and irradiates the dust particles. in this process, the irradiated dust particles will reflect laselsignals. And the detector can calculate the concentration of the dust based on a specific algorithm by detecting theintensity of the reflected laser signal.
