The DSL-340 uses the innovative Dynamic Detection Principle (DDP) which measures fluctuations in the intensity of a light beam, using a folded beam Transceiver / Reflector arrangement. Increased particulate density in the stack causes the amplitude of these fluctuations to increase. When calibrated against standard reference measurements, the amplitude of this signal relates directly to the particulate concentration in the stack, and this can be used to present as a reading in mg/m³.
The DSL-340 has no moving parts, is of rugged design and has an excellent reliability record. Regular maintenance simply involves cleaning the optical surfaces which are easily accessible due to our latched head design. Both the TRX and Reflector heads are supplied with an air purge body, which when connected to a high volume source of clean air, keeps the contaminated stack gas away for the lens surfaces. An Aluminium air purge body is available for use on standard installations and a more advanced Stainless Steel air purge body is available for more demanding installations.
