LEAK ALERT 73 DUST FILTER LEAK MONITOR The Leak Alert 73 sensors provide powerful bag-leak detection with sufficient dynamic range and time response to track emissions from single and multi-compartment, pulse-cleaned bag filters FEATURES AND BENEFITS Designed to differentiate between gross filter failure and dust leakage from faulty/ failing filter systems, including bag filters ElectroDynamic™ Probe Electrification technology rejects signals outside a defined frequency range which virtually eliminates the effect of any particle contamination on the rod. Instrument drift and minimum detection level below 0.1mg/m 3 with leak monitoring to 500 mg/m 3 Fully configurable warning alarm and limit alarm levels with independent alarm delay Supports simple and flexible configuration via keypad/display or using the remote PC software tool

Elevating standards. For life. LEAK ALERT 73 DUST FILTER LEAK MONITOR PRINCIPLE OF OPERATION The Leak Alert 73 combines advanced signal processing techniques with ENVEA's unique ElectroDynamic™ Probe Electrification technology. When the sensing probe is installed after the bag filter, particles in the airstream interact with the sensing rod to induce a charge signature. The resulting signal is filtered electronically to reject signals outside a defined frequency range (including the DC Triboelectric signal), which makes the instrument less susceptible to changes in particle velocity and virtually...
