LM 3086 EPA3 offers the new performance standard in opacity/dust monitoring. It fulfills the U.S EPA 40 CFR Appendix B, PS1 requirements and is also approved by TÜV for German 13th BlmSchV and TA Luft.
Measuring principle
The measuring system is based on the single pass/dual path-architecture, illustrated by the enclosed picture. The laser beam sent by the laser unit crosses the measuring section only once and the receiver unit measures and evaluates the laser beam's weakening caused by dust content. Additionally, the laser unit transmits the reference signal around the stack via optical fiber to the receiver unit, 40 times per second. This system improves the long-term accuracy of the analyzer because in traditional analyzers with a dual-pass design the retro-reflector is excluded from the zero/span calibration. In the MIP analyzer, the optical reference path around the stack ensures that all affected surfaces are included in the calibration. The monitor automatically corrects for dirt that can accumulate on these surfaces.
