Ge dust sensor sm-pwm-01c
2019-07-13
GE's sm-pwm-01c is a dust sensor (air quality sensor) that uses optical methods to detect dust concentration in the air. In the dust sensor, there is an infrared diode and an image sensor. Their optical axes intersect. When the airflow with dust passes through the intersection area of optical axes, the dust reflects the infrared light, and the reflected light intensity is proportional to the dust concentration.

Introduction of mine dust detector
2019-06-26
The mine dust detector is used to measure the dust concentration in the ambient air. It is suitable for the rapid detection of coal dust and other dust in the industrial and mining industry. It can accurately and timely reflect the quality of respirable dust inhaled by dust exposed personnel and the dust pollution status in different dust workplaces,

Principle and application of dust concentration sensor
2019-06-19
The dust concentration sensor adopts the fine electrostatic measurement method to monitor the dust content on-line in real time, measure the electrostatic charge of the dust in the pipeline, and output the standard current related to the dust concentration in the conveying pipeline through the carefully designed calculation circuit

What is the principle of dust sensor
2018-11-06
The working principle of dust sensor is based on the principle of light scattering. Particles and molecules will produce light scattering phenomenon under the illumination of light, and at the same time, it can also absorb part of the energy of the light. When a parallel monochromatic light incident on the measured particle field, it will be affected by the scattering and absorption around the particle, and the light intensity will be attenuated.

What is the technology of powder concentration sensor?
2018-09-06
What is the technology of powder concentration sensor? In order to prevent the influence of conductive dust, condensate oil mist or water mist on the measurement signal formation, we provide special probe maintenance skills to ensure that the probe can work normally under these harsh conditions. The sensor probe does not need air purging, so it is wear-resistant and corrosion-resistant

PM2.5 laser dust sensor tells you whether haze is serious in spring
2018-08-07
In recent years, with the increasing frequency of haze, the household air purifier, which was rarely seen, has become popular. PM2.5 laser dust sensor tells you whether the haze in spring is serious or not. In use, many people only use it when the haze is heavy. In fact, the use of air purifier can not be solved only by opening it several times when the situation is serious. It needs users to use it for a long time to get the proper effect.
