Three Common Online Detection Methods for Dust Concentration Meters

The dust concentration monitor boasts fast response, high accuracy, and excellent stability, capable of measuring the concentrations of particles like PM2.5 and PM0.1 in the air. It provides crucial air quality data and is widely used in factory workshops, flour mills, coal yards, paint booths, polishing factories, metal factories, furniture factories, wood factories, stone factories, and bag dust removal scenarios.

Next, let's learn about three common online dust concentration detection methods with Xi'an's dust concentration meter manufacturer.

Aerodynamic Particle Size Detection Method: This method accelerates the sampling airflow of aerosols through an accelerated nozzle. As the airflow velocity changes, particles of different sizes experience different accelerations. Larger particles, with greater inertia and slower acceleration, take longer to pass through the detector. Two laser beams intersect in the detection area, producing light scattering signals. These signals are collected and focused on a photodetector by an elliptical mirror, which converts them into electrical pulse signals.

2. The aerosol is drawn into the instrument using a vacuum pump, and different sizes of aerosol particles are detected with a laser detector, employing the laser scattering intensity detection method. Particles of varying sizes produce different intensity scattering signals, which are then converted into electrical pulse signals by a signal processor, providing information on the number concentration of particles. This method is typically suitable for particle detection with sizes ranging from 0.3 to 10 micrometers, and even larger.

3. Electrical Mobility Measurement Method: After the aerosol is吸入 into the instrument, it is subjected to force migration in the electric field. The equilibrium distribution of the aerosol is achieved by neutralizing the excess charge on the aerosol surface with positive and negative ions generated by the aerosol neutralizer or high-voltage discharge to ionize the air. Through this method, the particle size concentration distribution of the aerosol can be accurately detected.
