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.
