EXO Dust Monitor for Wet Gases

EXO is an extractive, isokinetic, and temperature-controlled continuous particulate monitor designed for wet industrial processes. It is the ideal solution for emission monitoring in challenging wet conditions, such as downstream of wet scrubbers or in condensing environments.

– System Components: Includes a heated sampling probe, an optical XO sensor module, an integrated touchscreen GUI, and a weatherproof powder-coated steel enclosure utilizing an ejector vacuum system to draw flue gas samples.

– Working Principle (Optical Forward Scattering): Extracted gas samples are heated to vaporize moisture. Particles pass through an optical measurement chamber where LED light is scattered, and a detector measures particle concentration based on the scattered light.

– Output & Calibration: Displays measurement results in $mg/m^3$ or 4-20 mA values. The device requires calibration to specific process conditions using a standard reference method after installation.

EXO is often used after Wet scrubbers, such as
– Spray Towers
– Tray towers
– Packed bed & ionized packed bed
– Fiber Bed scrubber
– Venturi scrubber
