PRODUCT DESCRIPTION

The Model D-FW 230/231 Filter Monitor by the DURAG Group can be used for continuous monitoring of filter installations in flue gas dusts, duct work for dust extraction. The filter monitor is ideal for use in a baghouse and is placed on the clean-gas side, behind the filter, and will report any defect. By using filter monitors at the most important emissions sources or filters, appropriate action may be taken in event of a malfunction to prevent or limit damage by shutting down the defective filter chamber.

The D-FW 230/231 Filter Monitors operate according to the principle of tribolelectric measurement. When dust particles collide with one another, they acquire an electrical charge. If these electrically charged particles strike the measuring probe is thus proportional to the number of particles colliding with it. The result will accurately correspond to dust emissions, since it depends not only on dust concentration, but also accounts for the velocity of the particle flow.

The D-FW 230/231 is in-situ continuous monitoring and had adjustable integration time. Its compact design in conjunction with it sturdy construction and no moveable parts will ensure longer lifetime and there is an easy straightforward installation.
