In industrial production often produces dust, dust and other small particles, workers long stay in the dust concentration of the environment will seriously affect health.PM2.5 sensors can detect dust particles within the specified range, and dust control is an important aspect of labor health.Scientific labor and health monitoring requires a sound testing technique. The following is a brief introduction to the application of PM2.5 sensors in industrial dust monitoring.
Dust, that is, dust is a dispersed phase aerosol, usually produced in the workplace, such as mining, casting, textile production process, dust material transport and agriculture, forestry work.The larger the dust particle size, the easier the settlement.In general, dust with a particle size greater than 5 can settle quickly.In addition to the chemical composition and amount of dust deposited in the lungs, the harm of dust to the human body is also related to the particle size in the respiratory system and the location of its deposition, especially the dust deposited in the alveoli due to the particle size.
In the production process, industrial and mining enterprises will produce a large amount of dust, which will not only harm human health, lead to occupational disease, but also accelerate the mechanical wear.It shortens the service life of precision instruments and can be explosive under certain conditions.Dust is produced in the production process of industrial and mining enterprises in a variety of production processes: such as drilling, blasting, mining and cutting, top coal, construction, cement production, open pit mining stripping, crushing, mineral processing and screening.Production workers work in a high concentration of dust environment for a long time, inhaling a large number of fine dust, serious harm to human health, leading to coal lung disease, coal silent lung disease and other occupational diseases.In order to protect the health of workers, it is necessary to detect and control dust for production.PM2.5 sensors should be installed in the working environment to detect the environment and ensure that excessive dust will not be inhaled.
Dust concentration directly affects the severity of dust hazards.It is an important measure to measure the occupational health status of working environment and evaluate the effect of dust technology.The filtration method is mainly used to determine dust concentration.When measuring dust concentration, PM2.5 sensors are used to extract a certain amount of dusty air.When dusty air passes through the filter membrane, it prevents dust from entering the filter of known mass, and the amount of filter increases according to the mass of the filter. The amount of air can be used to know the dust concentration at the measurement point.
Leftmann recommends the LD16 laser dust PM2.5 sensor
LD16 laser particle sensor is using the scattering principle to test the dust particles in the air of the small module, has small volume, high precision, good repeatability, consistency, real-time response can be continuous acquisition, strong anti-jamming capability, USES the ultra-quiet fan, 100% sensor testing and calibration, etc, need to know the detailed product parameters, please consult customer service.
