▎Product Introduction ：
The NA100PT Remote Transmission SF₆ Hybrid Gas Density Relay is specifically designed for detecting the density of SF₆/N₂ mixed gas in high-voltage switches. It can display the gas density on-site and trigger an alarm through output switch signals when the density reaches the set value. Since SF₆/N₂ mixed gas is more sensitive to temperature and significantly affected by it compared to high-purity SF₆, traditional density relays cannot meet the on-site application requirements.
▎Key Features ：
1.Combines highly reliable mechanical components with high-precision, intelligent electronic systems.
2.Features real-time remote transmission of hybrid gas density data, enabling online remote monitoring functionality.
3.Core components use imported materials to ensure product quality.
4.Suitable for diverse environmental temperatures and altitude conditions.
5.Offers multiple installation and alarm solutions tailored to customer requirements.
