Leading Technology for Emission Monitoring and Process Control

Light Scatter

These instruments measure the scattered forward light from a laser source. The measurement volume in the sensor probe is positioned in a representative location within the stack. The scattered light response is directly proportional to dust concentration. The instrument optimises its resolution and zero drift characteristics, meaning accurate measurement below 0.1 mg/m3 as well as rugged operation in stacks where emissions exceed 100 mg/m3.

 

The ProScatterTM Forward Scatter technique used collects the total cone of scattered light from particles in the measurement volume. This patented measurement method increases the instruments signal to noise ratio giving high stabilty at even low dust concentrations (< 0.1mg/m3)

 

The instrument provides a precise measurement of particulate concentration. Unlike the probe-based light scattering technique, the measurement and detection volumes are larger, offering more resolution and better minimum dust level detection capabilities. In addition, ProScatterTM Forward Scatter technology greatly reduces the effect of changing particle size to calibration and measurement errors found in other Scattering, Opacity and Triboelectric based monitors.

 

These sensors are able to function in process temperatures up to 400ÂșC.
