SF6 Gas Density Meters

Based on long term experience from over 100,000 density switch installations, GDC was developed to match HV manufacturer demands for quality, reliability and cost.

• High Voltage Circuit Breakers
• Circuit Switchers
• GIS Substations
• Gas insulated High Voltage Bushing
• GIL sections

• Visual indication of density level
• Uses reference chamber principle ultimate stability and repeatability
• Up to four independent contacts with decreasing or increasing thresholds

• Able to follow the Isochor even in liquid phase of SF6, that means no false alarm in low temperature
• Ability to calibrate a Self-diagnosis contact to check leakage in reference volume.
• No contact bouncing
• Shock proof
• Designed for outdoor installation
• Maintenance free
• Available with continuous monitoring analog output signal for remote monitoring and totalization of fugitive SF₆ emissions and SF₆ refill maintenance forecasting.
