Device detects filter failure
August 2007
Sensors & Transducers
The Durag D-FW 230/231 filter monitors are designed for continuous in situ monitoring of filter installations in flue gas ducts, duct work for dust extraction and similar applications. The instrument is placed on the clean gas side, downstream of a filter and reports any defect in the operation allowing appropriate action to be taken.
The low cost filter monitors require minimal maintenance and operate according to the triboelectric measurement principle. When dust particles collide with one another, they acquire an electrical charge, and if these electrically charged particles strike the measuring probe, the charge is transferred. The current flowing through the 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 is designed for single applications while the D-FW 231 is suitable for use in a multifilter plant where supervision of all filters is performed by a central processing unit.
Ideal for filter breakthrough monitoring, the compact units have an adjustable integration time, no moving parts, and a fast on-line performance-check capability.
