LSS2004 Laser Backscattering Monitor
Measuring Principle
The laser beam passes across the stack or duct work and is reflected
by the dust particles, the reflected light is then detected by the
photoelectric sensor. The intensity of reflected laser signal is
proportional to dust concentration, by which the resulting signal is
analyzed to yield dust concentration.
FEATURES AND BENEFITS
- Online continuous monitoring for various emission sources
- Combined techniques: adaptive stabilization, dynamic adaptive phase-lock amplification
- Very low zero drift, patented technology of online calibration
- Compact, easy to install, anti-lightning, high adaptability, low cost and less maintenance
