The pre-treated air flows to the sensor body, which is stably mounted on the bottom shell via a sensor mounting block. This allows for accurate detection of dust particles in the airflow, converting particle signals into identifiable electrical signals. The signals detected by the sensor body are transmitted to the main board, which is mounted on the bottom shell via a main board mounting plate. The main board analyzes, processes, and calculates the signals to obtain relevant dust particle data. Simultaneously, the main board coordinates the operation of all components, and a DC power module supplies power to the fan driver and other components, ensuring power supply. The circuit system is stable; the processed data can be displayed on the touchscreen, which is mounted on the upper shell with screen fixing components. The instrument's protective film serves to protect the screen, allowing users to easily view test results and set parameters. If needed, a printer can print the test data. The USB and DB9 interfaces enable data interaction with external devices, transmitting test data and ensuring uninterrupted subsequent testing processes. This ensures the reliability of the test data from the source, making the collected airflow samples purer and laying the foundation for accurate testing. The test results are closer to reality, meeting the high-precision testing needs of clean environments. It also allows users to view results and modify parameters at any time. From the testing process to data application and the device's own practicality, this design enables the dust particle counter to accurately, stably, and flexibly serve various scenarios requiring dust particle detection, helping to control environmental cleanliness.
