SF6，O2，Temperature and Humidity Transmitter

SF6、O2 Dual-function transmitter（Touchscreen Version)

In response to the current situation in the power system that emphasizes safe production, it adopts highly stable O2 sensors and infrared principle SF6 gas sensors to continuously detect the content of O2 gas and SF6 gas in the ambient air. It is specially designed and developed to provide personal health and safety protection for the staff in rooms equipped with SF6 devices.

This system can be widely applied to various voltage levels of SF6 switch rooms, combined electrical apparatus rooms (GIS rooms), SF6 main transformer rooms, etc.

SF6 and O2 two-in-one transmitter: It is used for continuous detection of O2 gas content and SF6 gas content in ambient air. It features digital output, bus design, flexible networking, and strong compatibility. The collected data is converted by A/D and then transmitted to the host via the RS-485 bus. It is generally installed below the SF6 switch and 100mm above the ground.can be fixed by wall mounting, magnetic attraction or special bracket. The working power supply is AC220V.
