Particulate monitoring is a critical factor for mines and mineral processing plants, where industrial pollutants are problematic. Many dusts can be hazardous or combustible, and those mining operations generating or handling dust can require special solutions to monitor and minimise emissions. Auburn Systems offers a new, unified DC/AC dust monitoring platform, known as TRIBO.dsp. The system is the result of a two year design and development project.

As dust particles collide with, or closely pass 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, the TRIBO.dsp unified U3000 series combines the benefits of each method, providing the user with a “superior reliable and repeatable signal”, with electrical interference resistance – even in harsh mining 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.
