Gas Monitoring System

Gas monitoring system is an intelligent system for real-time detection, analysis and recording of gas composition and concentration in the environment. It is widely used in industrial safety, environmental protection, petrochemical, energy production and other fields to ensure safe, compliant and efficient operation. Sino-Inst can customize products according to user needs, and also supports functions such as output signal fine-tuning to facilitate system networking and maintenance.

1. Standard bus RS485 and 4~20mA standard signal output at the same time. 1 group of relay switch output, optional frequency output 200-1000HZ, HART protocol signal, 1~5 output, wireless transmission (10-50 kilometers or unlimited distance). It can be remotely monitored in real time by wire or wireless, and the data can be uploaded to the mobile phone or transmitted to the Environmental Protection Bureau, other monitoring centers, monitoring equipment, monitoring computers through the local area network and the Internet, and the concentration of the site can be monitored in real time through free host computer software or gas alarm controller.

2. Compatible with various secondary meters, data acquisition modules, PLC, DCS systems. It can directly drive solenoid valves, fans, alarms and other equipment. It can also drive high-power equipment by driving intermediate relays.
