DSL-340

Double pass dust monitor for monitoring dust emissions using ddp

The DSL-340 Dust Monitor is an optical instrument designed to measure the concentration of dust or particulate matter in exhaust gas passing through a duct, stack or flue.

Features

Dynamic Detection Principle

Innovative Dynamic Detection Principle (DDP) measurement technique

Less susceptible to drift

Immune to gradual reductions in absolute intensity of the light signal so less susceptible to drift

Unit of measure

Measurement reading as mg/m³ (when calibrated against standard reference measurements)

Calibration

Internal electronic calibration check capability

Rugged construction

Rugged 316 stainless steel construction

Interface options

DSL-340 MkIII

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 dust or 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 dust concentration in the stack and this can be presented as a reading in mg/m³.

Optional accessories

Operator interface (OI)
90-260 Vac model available
Mounting flange installation kit
Laser alignment tool to assist with installation
Air purge blower kit (110 Vac / 230 Vac / 415 Vac)
Compressed air purge kit
Reference filters for routine calibration check of the instrument*

Benefits

Significantly less susceptible to drift than standard opacity monitors
Better accuracy over shorter path lengths, i.e. smaller duct diameter
Simple to install, commission and operate with an excellent reliability record
Rugged design with no moving parts so low maintenance
Latched head and lid design to enable ease of access for installation and maintenance
