Laser Dust Sensor Sensor Construction: Fig4. Sizes Installation Method: The dust collection hole is the air inlet inside the sensor, which needs to keep good contact with the external air; the fan is installed at the air outlet inside the sensor. When the sensor is installed and working, must avoid strong airflow interference around the sensor; if it cannot be avoided, try to keep the external airflow direction perpendicular to the internal airflow direction of the sensor. When designing the detection cavity of the whole machine, the effective area of the sampling port of the sensor should be...

Laser Dust Sensor Note: The picture shows the data comparison between the conventional ZH06 laser particle sensor and TSI8530 in the test environment. Abscissa : Testing time related parameters Ordinate : The concentration of particles in the test environment (with TSI8530 data as reference, unit: μg /m³, environmental resolution: 1μg/m³). Attentions: 1. It is forbidden to remove the shield cover of the sensor and the internal fixing screw of the sensor, because the shield cover of the sensor is connected with the internal power supply of the sensor through the internal spring. If the shield...
