Simple and Reliable Gas Sampling the Harshest Industrial Environments

The PSG Plus DSBP Series of heated gas sampling probes, from AGT-PSG, are used for continuous extractive gas analysis. They facilitate trouble-free representative sampling of very hot gases, often highly loaded with dust and water vapour.. A typical application would be process measurements in the cement industry.

The intelligent design, with optimum gas guidance, enables the filtration of sample gas at the outer filtration surface of 212cm2, which is the largest on the market. Changing the filter is quick and simplefilter without any need for tools or dismounting the heated sample line. PSG Plus DSBP’s extremely simple maintenance is enabled due to a sophisticated corkscrew mechanism, which makes opening the sticking filter housing lid an effortless task. The holohedral tight high performance ring heater, in combination with the tight thick-walled glass fibre insulation jacket, ensures homogeneous heating of the complete PSG Plus DSBP to 180°C. The dual stage back purge, with 12x1mm tubing, is controlled by optional mounted Coax solenoid valves with a 10mm passage.

Having the largest filtration surface on the market in combination with the homogeneous heating assures AGT PSG’s customers that dust will always be separated reliably in the PSG Plus DSBP without water vapour condensation and therefore without blocking the filter. For elevated dust concentrations of up to 280g/m3 the PSG Plus DSBP is equipped with an ultimate effective double stage back purge with 10mm passage which is a unique feature. Operating in this way means that the filter, as well as filter chamber, are purged thoroughly and dust is purged back almost completely into the process. The membrane coated ceramic filter with 0,3μm porosity offers a further boost to the effectiveness of the great back purge system.

In the last edition of International Environmental Technology AGT-PSG’s Marketing Director, Jorg Lang, discussed a solution to long term and stableresults, whilst maintaining a low cost of ownership. The article can be found on the International Environmental Technology website* (www.envirotech-online.com). AGT will be exhibiting at CEM16, in Budapest, which will be a great opportunity to see the technology first hand and discover how your CEMS’ efficiency can be improved.
