The main principle of the dust concentration detector

Ningxia Dust DetectorAchieving dust concentration detection through various principles, including light scattering, beta-ray absorption, and alternating electrostatic induction methods. Below is a detailed explanation:

Principle

Light Scattering Method

Utilizing laser diodes as the light source, the intensity of dust particle scattering is proportional to its concentration. Concentration is calculated by measuring the intensity of scattered light. This is the current technology in use, featuring real-time monitoring and rapid response.

Beta-ray Absorption Method

By utilizing the principle that β-rays lose energy as they pass through dust-laden filter membranes, the method calculates concentration by comparing the intensity of radiation between clean and polluted filter membranes. This technique boasts high precision and is commonly used in scenarios requiring measurement.Ningxia Dust Concentration Detector Manufacturer

‌Electrostatic Induction Method‌

By monitoring the dynamic charge changes produced as dust particles pass through a probe, concentrations are measured and converted into electrical signals. Suitable for online monitoring and real-time data collection.

Usage

Environmental Monitoring: Measure dust concentration in the air to assess air quality and pollution levels.

‌Industrial Applications: Monitor dust emissions in power plants, mines, chemical plants, etc., in compliance with environmental protection regulations.‌

Health and Safety: Ensuring personnel health through disease prevention and labor hygiene initiatives.

‌Product Testing: Assessing Air Purifier Efficiency or Air Conditioning System Cleanliness‌
