Pump suction dust detector

The XHFC-3A pump suction dust detector uses a laser as the light source for light scattering rapid dust measurement. The measurement principle is that when light is irradiated on suspended particles in the air, scattered light is generated. Under certain particle properties, the scattered light intensity of particles is proportional to their mass concentration. By measuring the scattered light intensity and applying the mass concentration K value, the mass concentration of particles can be obtained. The instrument is a new type of dust measuring instrument that can simultaneously monitor TSP, PM10, PM2.5, and has functions such as temperature and humidity compensation and automatic calibration. It can effectively reduce the impact of low temperature and humidity on measurement values, improve measurement accuracy in high humidity climate environments, and continuously monitor particulate matter in the air online.
This instrument has the functions of dust sampling inlet and outlet, filter barrel device, and can protect the service life of the vacuum pump, improving the overall service life of the instrument. It can be continuously monitored in high temperature environments and can work stably and reliably in high temperature environments at installation sites. Capable of working continuously for 7x24 hours, with functions such as fault self inspection and automatic restart.

1. Accurate data: laser principle detection, industrial grade photoelectric induction;
2. Adopting pump suction sampling monitoring, the performance is stable, the service life is long, the data is accurate, the sensitivity is high, the error is small, and the consistency is good. It is equipped with a powerful German imported suction pump, which has fast response time, strong anti-interference ability, and is more suitable for sampling places that require longer sampling tubes.
3. Resolution: 0.1ug/m3 particle size, 0.001mg/m ³; Detect PM2.5, PM10, TSP;
4. Stable performance: able to adapt to different atmospheric dust composition, with independent parameter coefficient adjustment;
5. Data transmission: RS485 (Modbus standard protocol) or RS232, UART output; Provide switch output and can be connected to outdoor sound and light alarm devices, etc
6. Intelligent monitoring: Real time monitoring of various indicators of sensors, and timely feedback to users when abnormal states occur;
7. It can be customized separately according to customer requirements. [Short customization cycle]

1. The default sensor runs automatically after being powered on, and data is passively uploaded. The sensor works for 30 seconds and stops for 30 seconds (default 30 seconds, which can be selected through commands). This cycle is repeated;
2. The sensor also provides three other working modes, which can be switched through commands
3. If the sensor malfunctions, the status indicator light and buzzer will sound an alarm
Note: The optimal working state is to work for 30 seconds and stop for 30 seconds

1. Construction site dust detection system
2. Atmospheric environment detection system
3. New air intelligent control system
4. Intelligent Building Weak Current Control System
