Are you still worrying about the increasing data detected by the fan laser sensor? Pump suction laser sensor to solve all your worries!
If the fan sampling sensor is used for a long time, the dust will stick to the sensor cavity, and the detection data of the conductor sensor will begetting bigger. If you have used a fan sampling sensor before, I believe you must have encountered such a problem. Switching to a pumped laser dust sensor can help you reduce after-sales operation and maintenance costs.
One,product description
This sensor integrates laser particle detection technology and information processing technology. It is a model with good stability, high sensitivity,Good consistencyPumped laserPM2.5/PM10Sensor detection equipment, with digital output and analog output, easy to install, easy to maintain and easy to use, with temperature and humidity correction function, to avoid the phenomenon of data deviation due to excessive humidity.
ExcitePrinciple of Light Scattering,Sampling through a vacuum pump,Send the detection gas directlyEnter the laser sensor compartmentTo conduct sample analysis.The inlet and outlet nozzles are designed with wide inlet and narrow outlet and vertical output. After the sample airflow enters the photosensitive area, it is constrained by the surrounding clean air to maintain non-diffusion and avoid turbulent air flow,Dust remains on the optical lens, effectively keeping the sensor compartmenteasyContaminated by external factors, Make the sensor detection accurate and long-term stable and reliable.
The sensor has been aged, debugged, calibrated and calibrated before leaving the factory, with good consistency and extremely high sensitivity.

Reminder: The sensor uses pump suction sampling. The pump is a consumable for this product, and the consumable is not covered by the warranty. The service life of the pump is closely related to the working frequency and air quality. If you want to maximize the service life of the pump, please do not allow the sensor to work continuously without interruption. It is recommended that the program be designed every time1Work once per hour1Minutes, or every30Monitoring once a minute30Seconds, again or20Monitor once every minute20Seconds, so that the service life of the pump can be maximized.
Sensor principle and components
The sensor uses a 785nm laser, and fine particles have good scattering properties at this wavelength. The laser emits directional light, and the diameter of the emitted beam is only a few tenths of a millimeter. The beam passes through the collimating lens and the column transmission and then enters the gas chamber, and is scattered by the sample sucked by the vacuum pump. The scattered light is reflected by the mirror to the photodiode, and the particles are generated. The scattered light will generate a pulse signal of the same size through a photodiode, and then amplify the pulse signal through a precision operational amplifier, and then perform micro-processing calculations through the MCU to calculate the mass concentration value of the particulate matter with high precision.
In order to prevent the interference of the reflected light from the light beam in the gas chamber, a light trap is specially designed, and a filter is installed at the light trap, which greatly reduces the reflection interference of the light beam.
