Ksf6000 SF6 gas leakage quantitative alarm system



Functional characteristics



◆ advanced test principle



Based on the principle of sound velocity, the system can measure the leakage content of SF6 gas quantitatively and online in real time



Reliability



The system adopts double difference processing method, which effectively overcomes the influence of temperature and humidity on the measurement results and eliminates the defects of traditional products.
◆ curve analysis function



The monitoring software can analyze the change trend of SF6 gas content curvilinearly, effectively grasp the status of operating equipment, and really play an early warning role



Real time and quantitative detection of SF6 gas concentration in a wide range



The system can accurately measure the SF6 gas content in the air in the range of 0-30000 ppm, and display it quantitatively in full range.



◆ alarm threshold adjustment function



SF6 alarm threshold can be set within 50-2000ppm.



The threshold value of hypoxia alarm can be set within 15-20%.



Universal power protocol, seamless integration with integrated automation system



◆ multi parameter output
Dedicated electrical design, the whole machine has no adjustable components, high-grade, quality assurance components selection, excellent anti-interference performance.
