Auburn Systems 3000 seriesAuburn’s TRIBO.dsp U3000 series of electrostatic/triboelectric (TRIBO) bag leak detectors and solids flow monitors effectively measure dust, powders, and bulk solids, preventing unexpected downtime and food product loss. The proprietary core technology, TRIBO.dsp, unifies DC impaction (triboelectric) and AC induction electrostatic signals for superior accuracy, reliability, and repeatability. The U3000 series provide a stable and reliable wide range signal, with robust resistance to electrical interference to:

• Monitor flow/no flow of pneumatic conveying
• Confirm flow when batch is increased
• Monitor velocity of finished product and provide control of the system flow
• Monitor and offer early detection warnings of ambient or fugitive dust
• Offers early warning of impending filter failure shutdowns; allowing for non-disruptive, maintenance scheduling

TRIBO.dsp’s Working Principal
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. They can activate operational functions such as alarms and relays or can be calibrated to generate continuous 4-20 mA or digital signals for trending and recording purposes.

About Auburn Systems LLC
Auburn was the first company to introduce 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. The company remains the leading supplier of bag leak detection systems with more than 45,000 systems operating in the field at more than 5,000 diverse materials processing plants, world-wide.
