Product Description

Details

Commonly known as “Burst Bag” or “Broken Bag” monitors, the Dust Alarm 40 provides a basic filter monitoring solution. It detects significant increases in particulate loading, it indicates a failure in the plant.

The Dust Alarm 40 is a compact Continuous Filter Dust Monitor comprising a sensor and control unit, ideally suited for filter monitoring to ensure correct, expected filter performance. The clear, simple, icon-driven menu provides users with a language-free setup and system overview. 

Using PCME’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.

  • 4-20mA output (optional) scaled to 0-100% of primary alarm level (which is user defined), for external indication of dust level relative to alarm set point
  • High quality leak response with sufficient dynamic range and time response to track emissions from single and multi-compartment pulse cleaned bagfilters
  • Dual alarms for filter failure and early warning, user-defined to instantaneous or average levels above normal, with alarm delay
  • Separate control unit for remote installation with a full-colour LCD display with icon-driven menu and effective graphical user-interface for instrument configuration and dust / alarm level status

Process Conditions

The PCME DUST ALARM 40 is suitable for:

  • Stacks after bag filters, cartridge filters, cyclones
  • Flue gas velocities > 4 m/s
  • Non-condensing / dry flue gases*
