NOTE. If users choose surfaced mount, please be sure about the safety
distance between the sensor’s housing and terminal pins, avoiding short
circuits or other malfunctions.
Principle Description:
Sensor Construction:
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 fully
considered to ensure the smoothness of the sampling gas path as much as
possible. Small sampling areas and large air resistance will seriously affect
the accuracy of sensor data.
Typical Output Characteristics:
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:
- 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 parts, so as to reduce the impact of external interference on the sensor.
- Excessive impact or vibration will affect the accuracy and life of the sensor detection value, so the sensor should avoid falling or vibration when installed and used.
- This sensor is suitable for the detection of dust particles in ordinary indoor environments. The actual working environment should try to avoid oil&smoke environments, too large dust particles, and high humidity environments, such as the kitchen, bathroom, smoking room, outdoor environment, etc. If it is used in such environments, corresponding protective measures shall be added to the user’s equipment to prevent viscous particles or large particles from entering the interior of the sensor and forming accumulation in the interior of the sensor which will affect the performance of the sensor. (for example, in the working environment with floccules or fibers, the corresponding coarse filter net should be added ahead of the air inlet of the sensor to avoid floccules or large sundries from entering the sensor and blocking the light path of the sensor, thus affecting the detection accuracy of the sensor.)
- The fan is the air outlet, and the dust collection hole is the air inlet. During the use of the sensor, the sensor should not be directly placed inside the air duct of the purifier. If it cannot be avoided, an independent space structure should be set up for the installation position of the sensor. The airflow direction is as shown in ‘Installation Method’. The sensor should not be impacted by the airflow in the direction of the red arrow. There should be no obstructions within 2cm around the outlet of the fan. In this independent space, it should be avoided that the airflow from the outlet directly flows back to the inlet, which will affect the accuracy of detection.
- Under normal working conditions of normal temperature&pressure, the key component of the sensor-laser can work continuously for more than 10000 hours, and the life of the sensor can be greatly prolonged by setting the sensor’s sleep mode and interval working time. The maximum cumulative life of the sensor can be more than 3 years. Please refer to the user interface instructions for detailed operation methods, or you can contact our technical service staff by telephone or email.
- The sensor data mentioned in this manual is about to ensure the consistency of the sensors we produced, the comparison standard will not refer to any third-party testing instruments or data. If the user wants the final detection results to be consistent with the third-party testing instrument, the user can do data fitting correction according to the actual detection results.
Packing:
- Put the sensor into the Pearl Foam Tray as shown in the picture below.
- Put the whole plate of sensors in Small Box one by one, then puts a foam plate at the top. Each Small Box can hold 25 sensors.
