Laster dust sensor Installation Methods: 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 fully considered to ensure the...

Laster dust sensor Notes for VOC sensors: 1. Preheating time Sensor’s resistance may drift reversibly after long-term storage without power. It need to preheat the sensor to reach inside chemical equilibrium. Preheating voltage is same with heating voltage VH. The suggested preheating time as follow: Storage Time Suggested aging time Less than one month No less than 24 hours No less than 48 hours More than six months No less than 72 hours 2. Following conditions must be prohibited 2.1 Exposed to organic silicon steam Sensing material will lose sensitivity and never recover if the sensor absorbs...

Laster dust sensor Notes for Laser PM sensor: 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 cover of the sensor is removed, the anti-interference ability of the sensor will be poor, the output value of the sensor will change, and the performance of the sensor will be poor. In addition, and please pay attention to the metal shield of the sensor, avoid contact with other external circuits or conductive...

Laster dust sensor Packing: 1.Put the sensor into the Pearl Foam Tray as shown in the picture below. 2.Put the whole plate of sensors in Small Box one by one (Figure 11), then puts a foam plate at the top.
