Automatically adjusts for thermal effects using bi-metal strips or digital sensors, providing stable readings at varying temperatures.
Configurable alarm and lockout contacts trigger signals when gas density drops below preset thresholds, enabling timely maintenance or system shutdown.
Available in all-stainless steel construction with optional oil filling for enhanced shock and vibration resistance.
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.
