Highly sensitive sf6 Monitor for cables

Highly sensitive sf6 Monitor for cables

room monitors have detection limits around 1 ppm that is higher than the expected SF 6 concentration range in a normally ventilated indoor substation (in the 10-100 ppb range). The 3731 leak detection system can be installed in the local control room. Sampling lines (up to 24) will easily be laid out using existing control cable ducts or trenches.

    The NDIR based Flow EVO SF 6 sensor (100 Vol.-%) precisely measure the purity or SF 6 gas quality in gas-insulated switchgears, transformers and cables. The compact NDIR type Flow EVO SF 6 sensor (2000 ppm) is typically used in portable gas metres or stationary SF 6 leak detectors for checking compliance with the SF 6 concentration in the ambient air (MAC = 1000 ppm) of gas-insulated switchgears.
