The online dust particle counter is an online detection online particle counter that measures the size and number of dust particles contained in a unit volume of air in a clean air environment.
This online particle counter adopts a new international sensor for detecting the concentration of dust particles in the air. It is a high-tech product integrating optical and laser technology, electronic technology, computer technology, precision machinery, aerodynamics and other disciplines. It has high measurement accuracy ﹑Reasonable detection, stable performance, multiple functions, unique shape, small size, light weight, easy installation, etc. It is mainly used for online monitoring of clean environment cleanliness, evaluation of changes in ambient air dust particles, and online monitoring of ambient air quality and dust. and early warning, alarm, etc.
This transmitter is designed according to international general standards (ISO14644, EU-GMP) to detect particle size grades and detection sampling methods, and its performance indicators conform to national standards and national metrological verification regulations. It is widely used in environmental online monitoring in pharmaceutical, microelectronics, optics, medicine and health, biological products, atmospheric analysis, aerospace and other departments.
The transmitter adopts the principle of light scattering. The air is sucked into the sampling port and flows into the photoelectric sensor under the action of the vacuum pump. When the suspended particles in the air pass through the photosensitive area, the luminous flux proportional to their particle size is scattered. After photoelectric conversion, After amplification and processing, the equivalent diameter and quantity of the collected particles are obtained, and a communicable code is formed by the processor, and the detected data is sent by communication with the upper computer.
