1. Introduction SF6 electrical equipment, renowned for its excellent arc-quenching and insulating properties, has been widely applied in power systems. To ensure safe operation, real-time monitoring of SF6 gas density is essential. Currently, mechanical pointer-type density relays are commonly used, providing functions such as alarm, lockout, and on-site display. To enhance vibration resistance, most of these relays are filled internally with silicone oil.However, oil leakage from density relays
