Overview

SF6 oxygen dual gas transmitter can be widely used in power safety monitoring systems: real-time monitoring of SF6 gas leakage and oxygen content in environments such as 35KV SF6 switch rooms, 500KV, 220KV, 110KV GIS rooms, and SF6 combination electrical equipment rooms in substations.

Product Details

SF6 oxygen dual gas transmitter

The detector includes a sulfur hexafluoride detection unit, an oxygen detection unit, a temperature detection unit, and a communication unit. The detection of sulfur hexafluoride uses ultrasonic detection technology to overcome the disadvantages of short service life and poor stability. It can monitor the changes in SF6 gas concentration and oxygen content in the environment in real time, and transmit the detected data to the SF6 monitoring host through RS-485 bus.

Modular design facilitates setting different monitoring factors as needed.

Choose high-precision electrochemical and long-life infrared sensors.

Suitable for simultaneous detection of multiple gases, Gonghu Si allows for flexible selection and use. Automatic compensation sensitivity for environmental temperature changes.

Structure considers aerodynamic principles to achieve automatic real-time sampling. Specially designed for SF6 gas leakage monitoring and alarm system in power equipment.
