SF6 Gas Density Relay (WINFOSS-D6)

Product Overview

The SF6 gas density relay (WINFOSS-D6) is primarily used to monitor the density of SF6 gas in a sealed container. It is widely used in high-voltage electrical equipment that uses SF6 gas as an insulating medium and is suitable for harsh outdoor working environments. The density relay has two or three sets of contacts (defined according to different needs) that can issue overpressure, alarm, and lockout control signals, and it also has an indicator display. The density relay is filled with silicone oil to enhance its resistance to vibration and impact.
