Auburn Systems Tribo.dsp U3000 series bag leak detectors and solids flow monitors measure dust, powders and bulk solids. The series unifies DC and AC induction signals. As particles collide with or closely pass by a probe, charge transfers occur, and the monitor detects the signal created by the changes in particulate concentration. The series monitors flow/no flow of pneumatic conveying; confirms flow when batch size is increased; and provides an early detection warning of ambient or fugitive dust, as well as an early warning of impending filter failure shutdowns. Users can activate operational functions such as alarms and relays or generate continuous 4-20mA or digital signals for trending and recording purposes.
