Product Introduction
The NA1100P Wireless Passive SF₆ Density Sensor delivers high-precision monitoring of SF₆ gas density, pressure and temperature in high-voltage equipment chambers, utilizing precision pressure/temperature measurement units with temperature compensation curves across extreme environments to achieve exceptional measurement accuracy, stability, reliability, interference resistance and protection grade, while transmitting real-time data to backend systems for trend analysis and alarm triggering to ensure SF₆ equipment safety and meet smart substation requirements for State Grid and Southern Power Grid.
Main features
1. The SF₆ density sensor can be selected in two forms: active wired and passive wireless; it can dynamically and real – time monitor the SF₆ density, pressure, and temperature indicators in the gas chamber.
2. The monitored data is uploaded to the monitoring center in real – time; the background system automatically draws trend change charts.
3. The NA1100P wireless passive SF₆ density sensor has strong anti – electromagnetic interference ability; it has wide – temperature – range compensation.
4. It meets the standard of the State Grid “Technical Specification for Smart Substations – Part 4: Digital Meters”.
