PCME VIEW Ex800–820 Electrostatic Dust Monitor

 I. Summaries of products

    Using the ElectroDynamicTM dynamic charge technology patented by PCME, the instrument samples the sensor exchange of electricity in specific frequency bands and the direct flow telecommunications from particle impact probes. The technology is better than the conventional straight-flow friction system and the communications system through the extended speed range. The instrument does not contain cross-sensitivity and therefore cannot change speed; It is also not affected by the contamination of sensor poles and can eliminate signal drift.

    • Separators and control units to provide additional security

    • PC-MEDustToolsPCsoftware provides robust and reliable emission reporting, real-time and historical data analysis for process control and forecasting maintenance

    • Entries, standard control devices with advanced charts and user interface monitors, including alarms, graphic change trends, data recording, 4-20mA output

    • Add a control device for the sensor network (up to 32 sensor channels) certified by the industry standard MODBUS, with multiple external input equipment (e.g., under the label, temperature and O2)

    II. Main characteristics of products

    Self-check function

    The PCMEVIEWEx800/820 has a comprehensive self-check function to ensure that emissions meet legal and regulatory requirements and provide early warning to operators on potential sensor issues. This prevents maintenance scheduling, reduces process dead time and increases data integrity.

    • Manual or automatic zero- or Zero-reference drift checks ensure self-detection of any electronic or signal detection failure. This quality assurance function is certified by the European and ASTM(US) bag-breaker monitoring standards.

    • The short-circuit inspection of probes allows operators to learn about short-circuits on the accumulation of particulate matter from sensor probes and to avoid associated measurement errors.

    2. Safe design of the explosive environment

    The PCMEVIEWEx800/820 designed a fail-safe device under two fault conditions, energy limit values to secure internal equipment and electro-separation to protect electrical components. Sensors in the hazardous area are connected to the control unit through a safe area regulator and, as part of the system's security design, simple sensor network connections are made through the “arry chain”.

    3. Advanced signal processing and signal diagnosis

    Accurate and rapid dynamic emission measurement allows operators to locate leaked bags in a multi-packed devarnisher. When the instrument combines the PCME PredictPCsoftware software, it has the capability to detect the failure of the dedustor:

    • A rapid dynamic range of 10,000:1 allows for the accurate monitoring of the bag's clean pulse while maintaining high accuracy in non-emission monitoring. Sufficient dynamic ranges are used to track the bag clean-up cycle for the prediction of bag failure and failure monitoring in “online” and “offline” states.

    • Scrolling (“Dynamic Data Collection Form” filter technology) data to measure particulate emissions on average and accurately
