How to choose dust concentration detector

What type of dust concentration detector should be used to measure dust explosions, and what range is generally required?

There are generally three conditions for dust explosion:

(1) Combustible dust is suspended in the air at an appropriate concentration, forming what is commonly known as a dust cloud;

All solid substances in the form of fine powder are called dust. Dust that can burn and explode is called combustible dust; dust that floats in the air is called suspended dust; dust that settles on solid walls is called deposited dust.

Explosive dusts include: metals (such as magnesium powder and aluminum powder); coal; grains (such as wheat and starch); feed (such as blood meal and fish meal); agricultural and sideline products (such as cotton and tobacco); forest products (such as paper powder and wood powder); and synthetic materials (such as plastics and dyes).

The dust generated in the production process of some factories and mines, especially the dust generated in the processing of some organic matter, can cause explosion and combustion accidents under certain specific conditions.

(2) There is sufficient air and oxidants;

(3) There is a fire source or strong vibration and friction.
