When the light is irradiated on the suspended particles in the air, scattered light is generated, in the case of a certain nature of the particulate matter, the scattered light intensity of the particles is proportional to its mass concentration, by measuring the scattered light intensity, the mass concentration k value is applied, and the mass concentration of particulate matter is obtained, which is the principle of light scattering.
A large amount of dust will be generated in mining farms, tunnel construction, flour production workshops, cement factories and other places, which are extremely harmful to the human body and the environment.
The industrial-grade laser dust analyzer is developed based on the principle of light scattering detection with reference to the industrial-grade product standard, and has the performance advantages of rapid response, accurate measurement, and abnormal alarm.
The laser dust meter is developed with reference to GB3836-2010 "General Requirements for Explosion-proof Electrical Equipment for Sexual Environment", and the explosion-proof mark is: explosion-proof mark for combustible dust environment: EXIB D21 IP65 T120, *Sexual environment: EXIB IIB T4 GB, which is an explosion-proof laser dust concentration detector. It can be applied to metallurgical, non-ferrous metals, building materials, machinery, light industry, textile, tobacco, commerce and trade and other industrial and trade enterprises with the risk of combustible dust.
Direct reading of data is an important performance feature of laser dust meter, it parameter MT163-1997 "General Technical Conditions for Direct Reading Dust Concentration Measurement Instrument" standard development, equipped with a large-size high-definition display, can convert the information collected on site into a digital display local display, belongs to the readable dust concentration detector, is very suitable for places that need to check the dust concentration on site.
In order to prevent the dust concentration from being too high, the alarm value of the dust concentration needs to be set first, when the detected dust concentration exceeds the set alarm value, the laser dust meter will send out a loud alarm sound through the built-in sound and light alarm lamp to remind the on-site personnel to deal with it in time; At the same time, the data is sent to the intelligent monitoring host through wired communication, providing data basis for the host to carry out intelligent control.
