The dust monitoring device continuously measures and monitors the amount of dust in the secondary exhaust of dust collectors and other equipment for 24 hours. In case of abnormalities, it monitors the changes in relative dust amount through alarm contacts and current signals. Detect the frictional charge of dust that touches the detection probe and output the relative amount of dust.
The installation and wiring of the equipment are extremely simple and conducive to environmental countermeasures.

Air (environmental) dust meter
Continuous monitoring of small particle concentration
Monitor for tiny particles in the air
Minimum detectable particle size: 0.3 μ m
Air dust meter is a sensor that monitors the mass concentration of dust and aerosols in the air. Dust and smoke from garbage dumps, offices, hotels, factories, etc. can be monitored. It can measure the concentration of PM2.5 and other pollutants, contributing to the working environment and safety. Besides, monitoring dust particles inside the control panel can effectively and reasonably utilize ventilation equipment.

Portable dust concentration monitor
Monitoring the dust generated by equipment to improve the working environment
For example, indoor dust in processing factories can affect the health of workers.
(Measures for preventing health hazards based on the Labor Safety and Health Law)
Furthermore, the dust generated by outdoor facilities such as unloading yards is directly released into the atmosphere,
Threatening the nearby living environment. (Air Pollution Prevention and Control Law)
Use a portable dust concentration monitor to visualize dust and try to improve the working environment.
The benefits of setting up a portable dust concentration monitor
Prevent nearby dust from occurring outdoors.
Improve the indoor working environment.
By controlling the energy-saving effect of dust collection equipment.

Dust switch
Small dust collector/filter damage detection
|
Particle size |
Above 0.3 μ m |
|---|---|
velocity of flow |
Above 4.0m/s |
|
output signal |
Open collector output (NPN) |
The dust switch implements 24-hour continuous monitoring of filter damage in general small dust collectors. Can quickly detect trace changes in dust during abnormal situations and detect dust leaks. Like a dust monitor, it detects the frictional charge of dust that comes into contact with the detection probe.
It is an extremely simple work environment protection switch for installation and wiring.
