SF6 and O2 transmitters use imported sensors with long life spans.
SF6 gas detection alarm error < 1%, oxygen alarm error < 0.5%.
The fan controller can control the existing fan.
The SF6 Gas Leak Alarm Monitoring System, equipped with sensors installed on equipment or pipelines, continuously monitors the concentration and leakage of SF6 gas. Upon detection of SF6 gas leakage exceeding the set threshold, the system promptly activates the alarm device, emitting sound or light signals to alert operators to take appropriate actions.

High sensitivity: Capable of quickly and accurately detecting even minor SF6 gas leaks.
Real-time Monitoring: Capable of real-time monitoring of SF6 gas concentration changes and timely alarms.
Multiple alarm modes: Alarms can be triggered through sound, light signals, and other methods, ensuring operators can detect them promptly.
Data Recording and Analysis: The system can record historical data on SF6 gas leaks and provide data analysis capabilities to help users understand the leak situations and trends.
High Reliability: The system utilizes reliable sensors and alarm devices, ensuring stable operation in harsh environments.

The SF6 Gas Leak Alarm Monitoring System is a specialized device designed for monitoring and alarming on SF6 gas leaks. SF6 gas is a commonly used insulating medium, widely employed in high-voltage power equipment such as substation and switchgear. However, SF6 gas has a high greenhouse effect and potential environmental hazards, making timely monitoring and alarming of leaks crucial.

The SF6 gas leak alarm monitoring system plays a crucial role in the operation of electrical equipment, assisting users in promptly detecting and addressing SF6 gas leaks, ensuring the safe operation of electrical equipment and environmental protection.
