EXO dust monitor consists of a heated sampling probe, optical XO sensor module, and an integrated panel PC, which are housed in a weather-proof powder-coated steel enclosure that is mounted on a frame. In a complete installation, the probe is inserted inside a stack perpendicular to the airflow using a flange. An external sample air blower supplies air to an ejector chamber at the end of the sampling line, creating a vacuum effect that draws flue gas through the internal piping of the device and ejects it back into the stack.
How?
During operation, the probe continuously extracts a gas sample, which is heated to vaporize any moisture. The remaining particles are directed through the measurement chamber of the optical XO sensor module.
Light from an LED is directed through the particle stream, which causes the light to scatter. A scattered light detector captures the scattered light and determines the particle concentration in the gas sample from the amount of scattered light.
The underlying method is called “optical forward scattering”.
Isokinetic sampling in variable flow conditions
Continuous Dust levels as low as 0,1 mg/m³
Sample stream isolated with air curtain to keep the optics clean -> long maintenance interval
Accurate linear measurement for all kinds of dust
Color touch screen for easy parametrization
LED light source covers different particle size distributions and is less affected by particulate characteristic
