NA1100P-W Wired Active SF6 Gas Density Sensor

Product Introduction

The NA1100P-W wired active SF6 gas density sensor is suitable for high-precision monitoring of the density, pressure, and temperature of SF6 gas in the gas chamber of SF6 high-voltage electrical equipment. The sensor uses a high-precision pressure acquisition unit and temperature measurement unit, and a temperature compensation curve is made in high and low temperature environments, enabling it to have excellent measurement accuracy. It features high stability, high reliability, excellent anti-interference ability, and a high protection level. Various monitoring data are transmitted in real-time, and the background system draws trend change diagrams. In case of any abnormalities, timely alarms are issued to ensure the safe operation of SF6 electrical equipment, meeting the construction requirements of smart substations of the State Grid and digital substations of the China Southern Power Grid.

Main Features

1. The wired active SF6 gas density sensor is available 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 monitoring data is uploaded to the monitoring center in real-time; the background system automatically draws trend change diagrams.

3. The SF6 gas density sensor has a strong anti-electromagnetic interference ability; it has a wide temperature range compensation.

4. The NA1100P-W wired active SF6 gas density sensor meets the State Grid standard “Technical Specification for Smart Substations – Part 4: Digital Meters”.

5. It meets the China Southern Power Grid standard “Technical Requirements for Digital Remote Transmission Meters in Digital Substations”.
