SF6 Gas Density Controller For use in voltage switchgear systems, converters and transformers. • Robust design with high operational reliability SF6 gas density controller with DILO connection piece for coupling part DN8 • Reliable switching • Welded and crimped design ensures absolute tightness • Bimetal compensated • Choice of integrated level switch • With application-specific process connection • Customer specific versions Application SF6 gas density controllers were specifically designed for the control of voltage switchgear systems. They provide highest levels of operational safety and reliability. The integrated bimetal compensation guarantees a maximum of operational safety in SF6 gas insulated switchgear systems. Made to specific customer requirements. The application-specific process connection is factory-welded to the measuring instrument. This means that a second, potentially leaky screw connection is not required.
