Online monitoring central processing system is a gas monitoring and processing solution for the complex environment of excessive temperature and humidity, oil, water and dust in the industrial production process. The system integrates pre-processing, gas monitoring and analysis into a highly integrated system. Intelligent original imported sensor detection technology, fast detection response, high measurement accuracy, good stability and repeatability; the explosion-proof product certification passed by the National Explosion-proof Electrical Inspection Center can be applied to various dangerous industrial places, and real-time monitoring data can be transmitted to the designated monitoring center, it can meet various industrial production or environmental monitoring needs. Widely used in environmental protection, metallurgy, petroleum and petrochemical, municipal, chemical and other industries in emissions monitoring, tail gas monitoring and process control.
◆ This system consists of a pre-processing system (including a constant temperature and humidity processing control device and an oil-water filter device) and a high-precision and high-performance gas detection and analysis system.
◆ The system is highly integrated, the overall volume is small, and the installation is convenient;
◆ Imported high-performance sensors with long service life; can monitor more than 2-3 kinds of gases at the same time;
◆ Using embedded 32-bit ultra-low power microprocessor, fast response speed, high measurement accuracy, good stability and repeatability;
◆ Automatic protection function against high concentration gas impact, with good anti-interference performance;
◆ Full software automatic calibration function for target points of level 2 to level 3 and above;
◆ The detector is equipped with an infrared remote control, and the full menu operation is realized through the remote control without opening the cover, which is simple and convenient;
◆ Three-wire 4 ～ 20mA output and RS485 signal output, relay output, data recovery, data storage and other functions;
◆ Support PPM,% VOL, mg / m3, mg / L concentration units to switch freely;
◆ Two cable entry ports, convenient for field installation;
◆ After analysis and detection, the gas can be returned to the pipeline again through the monitoring system; zero emissions, safer and more environmentally friendly!
◆ First-class mechanical design, the air chamber adopts military-quality high-strength aluminum profiles, wear-resistant and anti-corrosion, suitable for complex and harsh industrial environments, reasonable and scientific air chamber design to ensure the accuracy of real-time monitoring of sensors;
