Solid particle meter IPS KF

Purpose:

For on-line measurements of air pollution or combustion gases flow in chimneys or flues.
The measurement is isokinetic, it can be taken once for programmed air volume or can be repeated automatically in the continuous manner. There are no time limits for the monitoring.
As the result of measurement there are grain-size distribution of dust, ranged from 0,4 up to 300 μm, divided into 256 size classes and concentration (by quantity and by weight) in cubic meter for any chosen fraction of PM, e.g. PM10, PM5, PM2.5.
Additionally temperature, humidity and flow velocity are measured.

Measurement principle:

The measurement method of the IPS analyser is complex and consists in measurement with regard to influence of laser diffraction for the smallest particles in order to go on, for larger particles, in a continuous and gradual manner, to measure changes in the radiation stream scattered by moving particles. In this way, certain disadvantages of the “laser diffraction” used in the entire measuring range in which individual, largest particles yield weak changes in the diffraction pattern have been eliminated. There are no optical limitations for measuring individual, small and large particles in the IPS analysers.
The laser radiation stream in infrared not only identifies size of particles, but also renders counting them precisely in the entire measuring range possible.
An electric impulse corresponds to each participle. The impulse is proportional to the particle size. The set of particles is initially measured with the division into 4096 channels and converted (calibrated) into 256 size classes, which are available to a user.
