US Cemtrex Laser Dust Monitor - LM-3189 AZL/AZH

Description of LM-3189 AZL/AZH Laser Dust Monitor:
The LM-3189 AZL/AZH laser dust monitor is designed as an advanced semiconductor laser dust monitor. The LM-3189 AZH model has a measuring concentration of 20g/m3, while other technical specifications are the same as the LM-3189 AZL.

System Components of LM-3189 AZL/AZH Laser Dust Monitor:
Transmitter Unit L 318
Receiver Unit R 318
Display Unit M 318
Connection Cable
Purge Fan Unit or External Instrument Air Supply
Recording Software (optional)

Performance Specifications of LM-3189 AZL/AZH Laser Dust Monitor:
Direct continuous measurement of turbidity or opacity
Compact size, easy to install
Uses semiconductor laser light source
Zero and calibration can be selected in manual or automatic mode
Easy to install
Alarm relay with adjustable alarm value
Continuous 0-1V voltage and 4-20mA current output
Digital LCD and analog display of opacity
4 ranges (0-0.03 D, 0-0.1 D, 0-0.3 D, 0-1.0 D)

Advantages of using semiconductor laser in LM-3189 AZL/AZH Laser Dust Monitor:：
Good beam focusing, beam diameter only a few millimeters, so only a small hole of 20-50mm diameter needs to be opened in the flue wall for installation
Good stability and long service life. Components using traditional light sources wear out quickly, while semiconductor laser sources can last up to 10 years
Due to the high intensity of the laser, the beam can easily penetrate high-concentration dust for measurement
Due to the monochromatic nature of the laser, the wavelength is known, making theoretical calculations more reliable in practical applications compared to traditional light sources with mixed light

Application Fields of LM-3189 AZL/AZH Laser Dust Monitor:
Continuous particulate emission measurement, max path length up to 40 meters
Max measuring concentration 2g/m3
This instrument is suitable for coal-fired or gas-fired power plants, cement plants, and blast furnaces.
