Description

LDM-100 Laser Dust Monitor

LDM- 100 monitors the gas turbidity and dust concentration real-time and continuously in each process pipe and emission flue by measuring the ratio of optical intensity after laser transmission and original optical intensity.

Features and Advantages

LDM-100 adopts reflecting style design, making all the photoelectric parts (sensors, laser) in the same environment temperature and improving the stability when rising measuring optical length and sensitivity. Base on the reflecting design, adjustment requirement is reduced and aseismatic ability is rose.

■ Adopts laser transmission method, transmittance, extinction and dust concentration are monitored at the same time;

■ In-situ installation. Measure rapidly and high precisely in viscous dust and high temperature;

■ High effect reflecting material technology. High detecting sensitivity and measuring stability;

■ Measuring probe take operation interface by itself. High centrality. Operate conveniently;

■ Modularize designed. Each function part is displaced easily and maintained conveniently;

■ Equip purging system and is right for each type of project and application.
System Composition
LDM-100 comprises transmitter unit, reflector unit, connecting unit and purging unit (refer to Figure 2-1). Detecting laser from diode laser beam driven by the transmitter unit passes through the measured environment and is reflected to the sensor module of transmitter unit by optical unit of reflector unit. After photoelectric conversion and microprocessor analysis, measuring result is calculated.
