The online monitoring and pretreatment system is applied to 24-hour continuous online monitoring of on-site gas concentration. It is equipped with a 7-inch high-definition color screen to display on-site concentration, over standard on-site audible and visual alarm (optional), remote signal GPRS, DTU, Lora, and another transmission. The gas sensor of an internationally famous brand is adopted. The main detection principles include gas sensors based on the principles of electroche. Optional 1-6 kinds of compound gas detectors The concentration display unit can be switched freely A variety of communication methods are available Real-time monitoring via wired or wireless remote transmission, network transmission, 3-wire 4-20mA standard signal and standard bus RS485 (Modbus-RTU) output at the same time, optional frequency output 200-1000Hz, Hart protocol signal, 1-5V output, 2-wire 4-20mA, SMS alarm, wireless transmission (2-5km or unlimited distance), compatible with secondary instruments, data acquisition modules, PLC, DCS system, can drive related equipment. Standard infrared remote control, through the infrared remote control function keys, can be a one-touch operation, can realize on dangerous occasions without opening the cover operation, such as: modifying the alarm point, concentration calibration, zero calibration, silence, restore factory, and other functions. Rich human-machine interface 1.7′ HD color screen, display real-time concentration, alarm status. High-temperature gas detection (optional) Optional high temperature and high humidity pre-treatment systems can detect high-temperature flue gas.
