The PCME LEAK ALERT 75 is a TUV approved Filter Leak Monitor suited to filter control applications after fabric filter type (baghouse) dust arrestment plant. The instrument is certified according to BlmSchV 27 class 3 (EN 15859)* and offers a rugged and reliable filter leak monitoring capability for plants requiring license, and is similarly suitable for meeting US ASTM D7392-07 for Bag Leak Detectors. Options for ATEX / IECEx category 1/2/3 for Dust Zones 20, 21, 22 and integrated or stand-alone control unit add to the system flexibility.

* equivalent to MCERTS 'Performance Standards for Automated Dust Arrestment-Plant Monitors' version 1, class 3 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.

  • 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
  • 0-100% or user scalable display, of assistance to plant operators wishing to manually scale the display to an approximate known dust level
