Product description DMS-200 dust monitor is a self-developed probe-in monitor, based on years of research on dust detection technology. Different from traditional back scattering dust monitor (such as DMS-100/MS-1000), DMS-200 installs dust measurement module at the top of probe, which directly stretches into the stack for dust measurement in close distance and it adopts laser forward scattering method to realize low detection limit. Features Adopt laser forward scattering method to measure dust concentration; the lower detection limit is as low as 0.05mg/m3 Employ gas curtain purging to protect laser and lens of detector end; purging gas is automatically heated by the temperature of stack inside feeler lever and achieve positive pressure dust prevention inside feeler lever High temperature resistance design of probe part Automatic zeroing and calibration of double optical path Support manual range calibration Support automatic range calibration Specification Measuring principle: Laser forward scattering Measuring range: 0～10mg/m3, 0～200mg/m3 (customizable) Detection lower limit: 0.05mg/m3 Indication error: ±20% Indication repeatability: 10% Flue gas temperature: ＜250℃ (no condensation) Ambient temperature: -40℃～＋45℃ Purging gas: (0.2~1)MPa, no water, oil or dust, consumption 5L/min Probe length: 1m, 1.5m (customizable) Weight: 15kg COMM interface: Rs485 (default), Rs232 (customizable) Analog output: Isolation 4-20mA output, maximum load 500Ω Supply voltage: 24VDC Power: ＜5W (when calibrating ＜15W) Dimension: 185mm* 185mm*1500mm Applications Apply to online monitoring of low concentrations dust in super clean emissions and development of space dust detection
