Core Characteristics and Advantages
Temperature Compensation
Automatically adjusts for thermal effects using bi-metal strips or digital sensors, providing stable readings at varying temperatures.
Dual Set Points
Configurable alarm and lockout contacts trigger signals when gas density drops below preset thresholds, enabling timely maintenance or system shutdown.
Robust Design
Available in all-stainless steel construction with optional oil filling for enhanced shock and vibration resistance.
Correctly Reflect Density Changes
By detecting whether SF6 gas is leaking. When a gas chamber leaks, the density indicated by the gas density meter decreases, triggering an alarm signal, alerting the operators to take timely measures to ensure operational safety.
Typical Application Fields
High-Voltage Circuit Breakers
Gas-Insulated Switchgear (GIS)
Transformers & Instrument Transformers
Guarding Electric Power Safety
Chemical Industry
Petroleum Industry
Pharmaceutical Industry
