Concentration monitoring system DustMonitor DM 800

measurementdusttriboelectric

The DustMonitor DM 800 is a calibrated system for continuous measurement of dust concentrations in exhaust pipes and chimneys, and for monitoring dust filters and dust extraction systems. The DM 800 is based on the triboelectric effect, is insensitive to contamination and is characterized by reliable measurement results and low maintenance costs. It is used to monitor sources of contamination and can ensure the correct operation of dust collectors and dust filters. The DustMonitor requires a constant air velocity in the stack, it is suitable for use behind bag filters, cartridge filters, cyclones and electrostatic precipitator (ESP). The measurement result in the range of 0.1 - 1000 mg/m3 is output as a trend signal or absolute value via a 4-20mA interface or via Modbus / RS485. In addition, two relays can be switched for pre-alarm and main alarm. This allows the process manager to react in time to changes in the process and prevent an increase in dust emission. The system is suitable for almost all fields of application of dust measurement, variants for temperatures up to 250°C, for aggressive media and for use behind electrostatic precipitators are available.
