SF6 leak detector

The SF6 Leak Detection System 3731 from LumaSense offers unmatched performance. Based on Photoacoustic Spectroscopy (PAS) technology, the System offers highly accurate, reliable and stable quantitative gas detection.

Standalone Multipoint SF6 leak monitor with superior photoacoustic detection
(detection limit = 6 ppb)
? Cost-effective solution for a direct and integral leak detection method applicable to a complete SF6-GIS
? Independent from any pressure or density reading
? Available in 12- or 24-channel configuration to monitor large GIS installation
? Simple installation procedure, not requiring any outage on your installation
? Highly reliable and stable for a low cost of ownership


The 3731 system can detect within a short Response time any excessive increase in the leak rate, enabling to decrease the number ? hence the cost ? of periodic leak checks while providing early leak detection.

Including a multipoint sampler with up to 24 different channels, the 3731 system enables an extensive Distribution of sampling points over the whole enclosed substation in order to maximize the coverage area and minimize the detection response time. The length of each individual channel can be extended up to 75 m.
It is only recommended to calibrate the gas monitor only once per year. The calibration can be done without the requirement of an equipment outage. The only other maintenance task necessary is changing the air filter on each active sampling channel.
