YLSS2004-IB Dust Concentration Monitor

Introduction:

The LSS2004-IB dust meter is designed for use in an explosion-proof environment and is suitable for the measurement of explosive gases and flammable dusts. It has the same functions as the LSS2004 series. Working principle: LSS2004-IB dust concentration monitor adopts the laser backscattering test principle to complete the determination of smoke concentration of the measured flue. The embedded high-stabilization laser signal source passes through the flue and illuminates soot particles. The irradiated soot particles will reflect the laser signal and the reflected signal intensity and soot concentration will positively change. LSS2004-IB can detect the weak laser signal of smoke reflection and calculate the concentration of smoke in the flue through a specific algorithm.

Features:

1 intrinsically safe explosion-proof. Signs: Ex ib II B T4 Gb (explosive gas)/Ex ibD 21 T120 (combustible dust)

2 Intelligent design, suitable for on-line continuous monitoring of various sources of smoke and dust.

3 uses a variety of advanced technologies. Including: optical power adaptive stabilization technology, large dynamic adaptive phase-locked amplification technology, extremely low zero-drift design technology, and harsh environment design technology to provide fast, reliable and accurate quantitative smoke emission data.

5 Unique patented online calibration technology allows zero and span calibration without removing the instrument.

6 Compact structure, simple installation, lightning strike resistance, harsh environment, low cost, and low maintenance.

7 provides a variety of output interfaces.
