In the era of rapid development of smart grids, the safe operation of SF6 high - voltage electrical equipment is of particular importance. The NA1100P - W wired active SF6 density sensor, your intelligent guardian, is specifically designed for high - precision monitoring of the SF6 gas density, pressure, and temperature in the gas chamber of SF6 high - voltage electrical equipment.
High - Precision Monitoring, Ensuring Safety
Featuring a high - precision pressure acquisition unit and temperature measurement unit, the NA1100P - W performs temperature compensation in high - and low - temperature environments, ensuring unparalleled measurement accuracy. Its high stability, high reliability, and excellent anti - interference capabilities eliminate your concerns about data deviation or false alarms, providing round - the - clock safety protection for your equipment.
Real - time Transmission, Intelligent Early Warning
The real - time monitoring data is uploaded to the monitoring center in real - time, and the background system automatically draws trend change graphs. Once an abnormality is detected, the alarm mechanism is immediately triggered, enabling you to respond promptly and ensuring the safe operation of SF6 electrical equipment. This intelligent management method greatly improves the efficiency and accuracy of equipment maintenance.
Diverse Options, Flexible Deployment
The NA1100P - W wired active SF6 density sensor is available in two forms: active wired and passive wireless, meeting the deployment requirements in different scenarios. No matter where your equipment is located, you can find the most suitable monitoring solution.
