The PCME VIEW Ex 800 / 820 is a Hazardous area certified Particulate CEM (Continuous Emission Monitor) typically used in stacks after Bagfilter and Cyclone arrestment plant in the Chemical Processing, Plastics, Steel and Food industries.
The 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.
Key Features
- Automatic Functionality and Quality Assurance Checks
- Explosive Atmosphere Safety Design
- Advanced Signal Processing and Diagnostics
Process Conditions
The PCME VIEW Ex 800 / 820 is suitable for:
- Stacks after bag filters, cartridge filters, cyclones
- Explosive atmosphere zones 0, 1, 2, 20, 21 and 22
