1. Application
SF6 gas density controllers were
specifically designed for the con-
trol of voltage switchgear systems.
They provide highest levels of
operational safety and reliability.
The integrated bimetal compen-
sation 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.
SF6 Gas Density Controller
• Robust design with high operational reliability
• Reliable switching
• Welded and crimped design ensures absolute tightness
• Bimetal compensated
• Choice of integrated level switch
• With application-specific process connection
• Customer specific versions
For use in voltage switchgear systems,
converters and transformers.
