2. Introduction to the Configuration of Online Dust Concentration Monitoring System

Online dust concentration monitoring systemCS-FM1001Composed of dust concentration sensors, instruments, alarms, and power boxes, it realizes online detection and real-time alarm of dust concentration in the workshop, allowing enterprises to grasp the dust concentration in the workshop in real time.

2.1 Dust concentration sensor and controller

2.1.1 Application of Dust Concentration Sensor

Using the principle of light scattering to directly measure the total dust concentration, the measurement data is displayed on site, and the frequency that is compatible with the safety monitoring system is outputRS485(Choose one of the two signals)For monitoring system processing, it is a monitoring instrument fixedly installed in the workplace. This sensor can be connected to a security monitoring system or used separately with a power source. The sensor consists of a sampling head, a detection device, a microcontroller system, and an exhaust system. Suitable for continuous monitoring of total dust concentration in the atmosphere of dust workplaces such as mines, cement plants, power plants, coal mines, construction sites, and research institutes. Can accurately and timely reflect the pollution status of dust in the workplace.

2.1.2 Technical characteristics of dust concentration sensor

1) The rated working current is small, greatly reducing the burden on the on-site power supply;

2) The input voltage range is wide, and the instrument operates within the input voltage range 12Ｖ～24ＶＤＣ(Intrinsically safe power supply)Can work normally within the scope;

3) Directly read the mass concentration of dust particles in the air;

4) We have absorbed and digested advanced dust detection technologies both domestically and internationally, utilizing the principle of light scattering to detect dust. The detection data is processed by a microprocessor to directly display the dust mass concentration and convert it into a data signal output;

5) By using infrared remote control to calibrate the parameters of the sensor, it is possible to adjust without opening the cover, making calibration easier;

6) Real time and accurate understanding of the dust concentration on site, as well as200-1000HZorRS485Signal, or achievable0-5V，4-20MAThe output of current can detect the trend of dust concentration changes, achieve long-distance transmission, and can also be compatible with various standards200-1000HZSecondary instrument connection for input.
