Product Features

LDM-100A Laser Dust Monitor

Introduction 

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

 LDM100 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. 

Based on the reflecting design, adjustment requirement is reduced and aseismatic ability is rose.

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

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

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

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

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

6.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.

Adopting laser transmission detecting technology, LDM-100 is with quick response and high sensitivity. In-situ measuring is used. The transmitter unit and reflector unit install on the flue directly by connecting unit.

Measurement Principle

LDM-100 adopts Laser Transmission Method to measure the dust concentration. The basal principle (refer to Figure 1.1) 

is using diode laser as the lamp-house. After the detect laser beams passing through the spectroscope, the reflected light is detected by the detector and forms referenced signals. Transmission light shines to the reflecting material through the measured environment with dust. After the reflected light traverses the measured environment again, it is detected by detector and forms measuring signals. According to the contrast of referenced signals and measuring signals, transmittance information caused by

 dust is obtained.
