The PCME STACK 990 is an approved particulate Continuous Emission Monitor suited to industrial applications in stacks after bag filters, cartridge filters, cyclones and process driers. The instrument combines regulatory approvals (TUV BlmSchV 17 and 13) for both dust measurement and leak monitoring, with reliable automatic quality assurance features, rugged operation and advanced diagnostics for the management and optimisation of arrestment plant.

Options include Ex Gas Zone 2 and Dust Zones 20, 21 and 22, up to 800°C stack temperature operation and Hastelloy® enhanced corrosion protection; The PCME STACK 990 is used extensively for particulate measurement (mg/m3) and bagfilter leak location across a broad range of challenging applications.


          Patented insulated sensor rod option for use in high humidity applications

Patented ElectroDynamic Probe Electrification technology 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.

  • Patented probe rod insulation monitor providing operator with early warning of possible probe short circuit. Unique to PCME, this technology enables predictive sensor maintenance scheduling, lower down times and additional confidence in signal quality
  • Additional system self-checks to validate measurement integrity including automatic Zero and Span checking
  • ATEX / IECEx category 3G/1D/2D/3D for gas zone 2 and dust zones 20, 21, 22
  • PC-ME Dust Tools PC software option to provide secure and powerful emissions reporting, real-time and historical data analysis
  • Entry and Standard control unit with advanced graphic and user interface screens, features including alarming, graphical trending, data logging, 4-20mA output.
  • PLUS control unit option for sensor networking (up to 16 sensor channels) via industry standard Modbus, multiple inputs for external devices (e.g. for Temp and O2 normalisation)

The PCME STACK 990 supersedes the DT990, an instrument proven in demanding CEM applications worldwide.
