Product Description
SFXL Online SF6 Gas Leakage Detector is composed of intelligent analog quantity collector, laser emission and light intensity monitoring unit, laser receiving unit, signal processing unit, etc., to achieve the purpose of real-time monitoring of SF6 gas concentration in the air of the area.
By using an open optical path, the concentration of SF6 gas in the area can be measured without sampling.
SFXL Online SF6 Gas Leakage Detector has the functions of gas analysis , analog input, switch input, protocol conversion, communication interface conversion, transmission and switch output control.
SF6 gas leakage alarm system overcomes the weakness of traditional SF6 detectors that must be sampling to measure the SF6 at appointed point.
The system has its own automatic concentration calibration function and does not require additional periodic calibration.

Features
Features of SF6 laser transmitter:
1. Using open optical path high-sensitivity mid-infrared laser absorption spectroscopy technology, eliminating the influence of laser intensity fluctuation and external environment.
2. It can quantitative detect and analyze the SF6 gas in regional air.
3. Real-time display of the SF6 gas concentration in the regional air.
4. Users can set the alarm concentration arbitrarily, it will alarm when the SF6 gas concentration in the environment exceeds the set alarm value.
5. Each SF6 gas laser detector can monitor the change of SF6 concentration in the range of 0.1~200m without any sampling device, only a reflector is needed. The working principle is: When the laser passes through the monitored area, it is reflected by the reflector and reaches the detector to achieve the detection of SF6 concentration in the entire optical path.
6. The measurement accuracy can be higher than one millionth; the detection resolution can reach the order of 1ppm.
7. It is high accurate, stable, reliable, durable and with easy operation.
