Continuous, optical extractive measurement of dust contents in wet and sticky exhaust gases
The measuring gas is sampled by a temperature-con- trolled probe, conveyed to a measuring cell and continuously diluted and dried with hot and dust-free ambient air.
For dust measurement, based on optical scattered light measurement, a laser lance unit in the measuring cell is streamed with the conditioned measuring air.
In the electronics of the operating unit the signal of the optical unit is converted to an equivalent dust signal.
YOUR BENEFITS AT A GLANCE
• relatively small required space
• compact device → only 1 sample fitting with integrated or separated return fitting necessary
• display option in mg/m3 by input of calibration parameters
• isokinetic gas sampling possible
