Apr 11, 2013 Comprising bag leak detectors, emission monitors, and solids flow monitors, TRIBO.dsp U3000 series measures particulate/dust emissions and dry solids flow. Core technology, TRIBO.dsp, unifies DC impaction (triboelectric) and AC induction electrostatic signals for optimal accuracy, reliability, and repeatability. Signals can be used to activate operational functions, such as alarms and relays, or generate continuous 4–20 mA or digital signals for trending/recording.
