The Leak Alert 75 is particularly suited for use on fabric filter type dust collectors (baghouses) and provides reliable and robust monitoring of particulate leaks from bags. With its compact cost effective transmitter design, pragmatic reliable monitoring can now be provided for all types of of industrial bagfilters. The instrument benefits, first from PCME’s unique ElectroDynamicTM Probe Electrification technology, secondly advanced features enabling the Leak Alert 75 to be configured for all types of bagfilters irrespective of cleaning sequence and finally an external display and self check option which provides added quality control. The Leak Alert 75 exceeds the requirements for a bag leak detector under EU regulatory compliance.

The Leak Alert 75 combines advanced signal processing techniques with
PCME’s unique ElectroDynamicTM Probe Electrification technology. When the sensing probe is installed after the bagfilter, 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 to virtually eliminate the effect of any particle contamination on the rod. In bagfilter applications the instrument provides a robust signal proportional to dust emissions which is used to monitor and detect bag leaks. The instrument has the necessary features to discriminate between the variation in dust due the bag cleaning sequence and real leak conditions.

In addition to providing leak location capability, the LeakAlert 75 is designed to meet all performance approvals as a “Dust Filter Leak Monitor” and relevant product approvals for dust filter leak location according to European and ASTM standards. The product has TUV approval as a filter leak monitor (BImSchV 27 approval) as a filter leak monitor and is suitable for meeting ASTM D 6023-03 for bag leak monitors. The instrument is provided with internal zero and reference Quality Assurance features required to meet these standards, saving the user considerable time in performing alternative manual procedures.
