Dust concentration and soot monitor
FIVES PILLARD

The OPASTOP® GP 2001 H is particularly adapted to the following applications:
* Continuous monitoring of dust emission concentration.
* Monitoring of filtration system emissions.
* Monitoring of flue gas opacity for maximum burner combustion.

A cone of light transmitted by fibre optic cable from a light source is shone into the measuring area from the scanner head. A fibre optic receiving cable transmits the reflected light from the suspended particles to a
photosensitive cell.

Four generations of equipment with over 30 years experience in the field
have given the GP 2001 H the following advantages:
* Reflection type measuring system, in-situ, giving:
* The best available sensitivity to low dust levels.
* Rapid response time.
* A single scanner head, completely separate from the electronics panel, giving :
* Easy to fit assembly.
* No scanner alignment required.
* High tolerance to temperature and vibration.
* Large back-lit interactive LCD screen, showing clear instructions
making it easy to understanding and use.
* Modulated light source eliminating parasitic light reflection.
* Modular design, enables easy maintenance and parts replacement.
* Automatic scale switch-over from low to high dust content enables a permanent reading of the measured value.
* Scanner head fits in place of all the preceding generations of OPASTOP® can replace all versions of GP 1000 H / GP 2000 H OPASTOP® scanner heads without modification.
