US Cemtrex Laser Dust Monitor - LM-3189

Description of LM-3189 Laser Dust Monitor:
The LM-3189 laser dust monitor is a cost-effective laser source dust monitor, suitable for detecting medium to high concentration dust (> 25 mg/m3) over a medium range of 3-10 meters.

LM-3189 Laser Dust Monitor System Components:
Transmitter Unit L 318
Receiver Unit R 318
Display Unit M 318
Purge Fan Unit or external instrument air source
Recording software (optional)

LM-3189 Laser Dust Monitor Performance Specifications:
Direct continuous measurement of turbidity or opacity
Compact size, easy installation
Simple construction, no moving parts, long service life
Adjustable alarm value for alarm relay
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)
Low maintenance

Advantages of using semiconductor laser in LM-3189 Laser Dust Monitor:
Good beam focusing, beam diameter only a few millimeters, so only a 20 mm diameter hole is needed on the duct wall for installation. Installation is simple, and the transmitter unit does not require strong purge air.
Good stability and long service life. Traditional light sources consume components 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 sources with mixed light.

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