Sulfur hexafluoride SF6 detector

With the rapid development of science and technology and the continuous progress of the industrial field, Sulfur hexafluoride (SF6), an important industrial gas, is more and more widely used in electric power, metallurgy, chemical industry, and other fields. However, the high toxicity and strong corrosiveness of SF6 also bring potential safety hazards. Therefore, accurate and timely testing of SF6 to safeguard the safety of the working environment and the health of personnel has become a focus of attention both inside and outside the industry.

Against this background, Fosensor has independently developed an efficient and accurate professional SF6 detector, bringing a new choice to the industry. This detector adopts advanced sensing technology and intelligent algorithms, which can quickly and accurately detect the concentration of SF6 and display the results in real-time. It is also highly stable and reliable, even in harsh working environments.

In addition to the basic detection function, this SF6 detector is equipped with a variety of intelligent features. For example, it can be connected to a mobile phone APP to achieve remote monitoring and alarm function. When the SF6 concentration exceeds the safety threshold, the detector will immediately issue sound and light alarms and send alarm information to the administrator via APP, so that timely measures can be taken to prevent accidents.


In addition, this detector also features simple operation and easy maintenance. Users only need to follow the instructions to carry out simple operations, and can easily complete the detection task. Meanwhile, the maintenance of the detector is also very simple, one only needs to replace the sensor and clean the shell regularly.

All in all, this professional sulfur hexafluoride detector brings a new choice for the industry with its high efficiency, accuracy, and intelligence. It will provide a strong guarantee for safe production in the industrial field and protect people’s lives and property.

Working Principle

SF6 detector for gas diffusion detection principle, when the target gas is into the gas probe part, the internal Industrial Infrared SF6 Sensor will be the first time to send out sensors. The sensor generates a certain electrical signal according to the gas concentration. The signal is amplified and processed by the circuit, and then the CPU outputs an accurate 4-20mA current signal, RS485 communication signal, 0-5V voltage signal, ZIGBEE, NRF, WIFI, GPRS wireless signal, etc., after AD sampling, temperature compensation, and intelligent calculation. Customers can collect these signals, and gas alarm control host, PLC, DCS, host computer, and other systems support the use of alarm and data reprocessing. In addition, the Sulfur Hexafluoride detector is equipped with a group of relays (switching signals), which can be linked with fans, solenoid valves, and other control equipment to maximize the protection of your life and property safety.
