The PCME LEAK ALERT 80 is a TUV approved Filter Dust Monitor suited to filter control applications after fabric dust filter type (baghouse) arrestment plant. The instrument is certified according to BlmSch 27 class 2 (EN 15859)* and offers a rugged and reliable filter leak monitoring capability for plants requiring license, and is also suitable for meeting US ASTM D7392-07 for Bag Leak Detectors. Integrated or stand-alone control unit options add to the system flexibility.

* equivalent to MCERTS 'Performance Standards for Automated Dust Arrestment-Plant Monitors' version 1, class 2 PM-CEM (August 2010)

Using ENVEA UK's patented ElectroDynamic Probe Electrification technology, the instrument extracts a specific frequency band from the induced AC current signature and filters out the DC current caused by particle collisions. The technology outperforms conventional DC triboelectric systems and alternative AC systems by extending the velocity range over which the instrument has no cross sensitivity to changing velocity, and is unaffected by contamination of the sensor rod eliminating concerns of signal drift.

PCME LEAK ALERT 80 advantages include:

  • High quality leak response with sufficient dynamic range and time response to track emissions from single and multi-compartment pulse cleaned bagfilters
  • System self-checks to validate measurement integrity including automatic Zero and Span checking
  • ATEX / IECEx category 1D/2D/3D for dust zones 20, 21, 22
  • Insulated sensor rod option for unmatched performance in high humidity applications
  • Powerful integrated user interface with keypad and display for intuitive instrument set-up
  • User scalable output, of assistance to plant operators wishing to manually scale the display to an approximate known dust level
