Leak monitoring unit of gaz sf6 - Amperis

Multi-Point Sampling in SubstationsUltra-Sensitive gaz sf6 Leak Detector - with Multipoint Sampler40+ Years of Experience with PasA 24 channel multiplexer is available that can sequen-tially draw gas samples from up to 24 locations. Integrating seamlessly with the Sulfr hexafluoride Leak Detector. This multipoint sampler extends its area monitoring capability. It enables a good spatial resolution in the leak detec-tion with a good flexibility in the choice of the sampling locations. Field Monitoring Ease of use, and long-term stability are required for the mostly unmanned GIS substations. With its low detection limit (6 ppb), and its accuracy over a high dynamic range, the permanent monitoring solution from LumaSense enables early leak detection in comparison with monthly visual checks of density gauges. The sf6 gas Leak Detector can complimentarily meet the health & safety requirements in enclosed areas where sf6 gas leaks may occur. Sampling points can indeed be located in low lying and confined areas where Sulfr hexafluoride would build up over its MAC level (1000 ppm) or even up to an asphyxia-tion risk level. Alarm relays can be set up on two...Get price
