Robust smoke density meter

March 2001 Analytical Instrumentation & Environmental Monitoring

The Durag D-R216 smoke density meter from OEN Enterprises, applies the two-beam alternate light method following the auto-collimation principle which allows the light beam to cross the measuring section twice. The unit measures and evaluates the weakening light beam caused by dust content within the measuring section. Typical monitoring applications include heating plants, industrial boiler plants, waste incinerators, dust extraction and filtering systems and emissions monitoring and control in the process industries. An electromagnetically actuated rotary diaphragm switches between the measuring beam and a comparator light beam. Comparative measurements of 2 s duration occur every 64 s for check value compensation.

A photocell receives the measuring and comparator light beam alternatively. As the emitter light is modulated with 25 Hz, no daylight influences will occur. A separate purge air fan keeps the heated optical boundary surfaces free from soiling. The unit is suitable for stack diameters ranging from 0,4 to 6,25 m, has a 4 to 20 mA output signal and meets IP65 requirements.
