The 7S-S6-GC is a mechanical, temperature-compensated density meter designed for SF₆ switchgear.
• Monitoring Unit: Includes pressure sensing probe and long-rod sealed connection assembly;
• Display Unit: Dial with temperature compensation (marked with pressure range and temperature scale).
• Temperature Compensation Design: Integrated temperature scale on dial corrects SF₆ pressure deviations at varying temperatures, ensuring measurement accuracy;
• Visual Status Indication: Red (low pressure) and green (normal) zones provide intuitive gas condition recognition;
• Sealing Adaptability: Long rod + sealed connection structure adapts to monitoring enclosed chambers in SF₆ charging equipment.
• Pressure Monitoring: Real-time display of SF₆ gas pressure reflects the state of the equipment’s insulating medium;
• Fault Warning: Alerts for gas leakage when pressure enters the red zone, requiring prompt maintenance;
• Operational Support: Combined with temperature scales, assists in determining whether actual SF₆ density meets insulation requirements.
