Basic Principle of Dust Monitoring Channel Light Source Receiver I 0 S E 0 Transmitter Detector Ex Ix Io = Light intensity at the source Ix = Light intensity at the receiver. Optical Quantities in Dust Monitoring: Transmission: T = (Ix / Io) x 100 % Opacity: Op = ( 1 - Ix / Io ) x 100 % Optical Density: D = Log 10 ( Io / Ix ) Extinction: E = Ln ( Io / Ix ) Ringelman : R = Op% / 20

Relation with Optical Values and Mass Concentration 1. Using a calculation formula: Concentration is as follows : M = (800 x x d / L ) x D, where M = Mass concentration in ( mg / m 3 ) = Specific gravity of the particulate matter in ( kg / dm 3 ) d = Average diameter of the particles in ( m ) L= Length of the light passage inside dust in ( m ) D = Optical Density ( Dimensionless number )

Relation with Optical Values and Mass Concentration 2. Using a reference method for calibration: Isokinetic sampling Taking samples to the filter and analysing them in the lab Costly and time consuming

Dust Monitoring Normally in optical dust measurements only scattering is important. Scattering depends on particle diameter and the light wavelength proportion: d/.

Cell Room Application This particular application is for safety control inside of a cell room. The customer (a battery manufacturer) was looking to measure the opacity of the smoke/mist coming off the cells. The fans in the room come on if the mist reaches a certain level of occupancy. It is essentially a worker safety application. This picture shows the room in which the monitors were installed (roughly in the center of the room, where the mist was intensely present). The whole room is about 140 ft. across. The customer chose this spot to mount the transmitter above the light grey metal beam on the wall.

Cell Room Application The customer chose this spot to mount the receiver in between the yellow steam pipes. General Arrangement Drawing
