Laser dust sensor PMS501

This PMS501 Dust Concentration Monitor employs Laser Forward Scattering principle, developed, designed, manufactured by Orthodyne for ultra-low dust emission applications. The integrated heating probe and flow control design reduces moisture interference. It is especially suitable for installation in working condition characterised with high humidity, low temperature, and low dust concentration. Applications > Extractive system used for continuous dust concentration measurement. > Dry and wet gas applications, including handling sticky dust > Typical applications include wet desulfurization outlets, dust collector inlets and outlets, and final outlets from thermal power plants, waste incineration plants, and various process industries Technical Features > Sample gas is heated in the heating chamber to evaporate water drops and mist, reducing humidity > Laser forward scattering principle ensures very high sensitivity in the measurement > Automatic calibration of the zero point and range, ensuring stable and reliable operation. > User-friendly interface with a large touch screen color display > Small and lightweight sampling probe facilitating easy installation and daily maintenance Measurement principle: Laser forward scattering principle with integrated extraction system > Range: (0-15-45）mg/m3 > Performance indicators: Linearity: ≤1% Zero drift: ±0.5%F.S. Span drift: ±0.5%F.S. Detection limit: 0.1mg/m3
