DC/AC Baghouse Emissions Detection

Particulate monitoring for hazardous dusts 2-year design / development Signals activate alarms, functions

AUBURN SYSTEMS introduced the first electrostatic/triboelectric (TRIBO) bag leak detectors and solids flow monitors to monitor and measure dust, powders, and bulk solids for environmental and process control applications. Now, it has developed a “unified DC/AC platform”for detecting baghouse emissions.  Particulate monitoring is a critical factor for manufacturing plants where industrial pollutants are problematic. Many dusts are hazardous or combustible, and those operations generating or handling dusts can require special efforts to monitor and minimize emissions in these areas.

“This schematic illustrates the new, unified DC/AC platform that represents the latest major technology advancement,” according to Auburn’s president and founder Ron Dechene,“This platform, known as TRIBO.dsp, is the result of a two-year design and development project, which will further broaden our markets well beyond the environmental monitoring field. We’re not only the creators of this measurement field but we’re the only company still improving it and now we have a colorful visual to explain our unique technology”.

As dust particles collide with or pass close by a probe, charge transfers occur. Tribo.dsp series products detect the signal created by the changes in particulate concentration, as in the onset of a bag leak or an increase or decrease in flow. 

Unlike monitors that use only the DC impaction or only the AC induction signals, thereby using only a portion of the complete electrostatic signal, TRIBO.dsp unified U3000 series combines the benefits of each method, providing the user with a better, more reliable and repeatable signal, with electrical interference resistance - even in harsh industrial environments. They can activate operational functions, such as alarms and relays, or can generate continuous 4-20 mA or digital signals for trending and recording purposes.
