In modern power systems, the safe operation of high - voltage electrical equipment is of utmost importance. To ensure that the density, pressure, and temperature of SF6 (sulfur hexafluoride) gas in high - voltage electrical equipment are always in an optimal state, we have introduced the NA1100P wireless passive SF6 density sensor. This sensor is specifically designed for SF6 high - voltage electrical equipment, featuring high precision, high stability, and high reliability, making it an ideal choice for your smart substation construction.
High - Precision Monitoring: The NA1100P SF6 density sensor uses a high - precision pressure acquisition unit and temperature measurement unit, and performs temperature compensation in high - and low - temperature environments to ensure extreme measurement accuracy. Whether it is density, pressure, or temperature indicators, real - time monitoring can be achieved, providing comprehensive data support for your equipment.
Real - Time Data Transmission: This SF6 density sensor supports both active wired and passive wireless forms, and can be flexibly selected according to actual needs. The monitored data is uploaded to the monitoring center in real - time, and the background system automatically draws trend change graphs, allowing you to keep track of the equipment status at any time and promptly detect and handle abnormal situations.
Excellent Anti - interference Ability: The NA1100P SF6 density sensor has excellent anti - electromagnetic interference ability and can maintain stable operation even in complex electromagnetic environments. At the same time, the wide - temperature - range compensation function ensures that the sensor can provide accurate measurement results under different temperature conditions.
Compliance with National Standards: Our sensor meets the State Grid standard "Technical Specification for Smart Substations - Part 4: Digital Meters" and the China Southern Power Grid standard "Technical Requirements for Digital Remote - Transmission Meters in Digital Substations", ensuring that your equipment meets national standard requirements in smart substation construction.
The NA1100P wireless passive SF6 density sensor is suitable for monitoring the density, pressure, and temperature in the gas chambers of various SF6 high - voltage electrical equipment. Whether it is a smart substation of the State Grid or a digital substation of the China Southern Power Grid, it can provide reliable data support to ensure the safe operation of the equipment.
The NA1100P wireless passive SF6 density sensor, with its characteristics of high precision, real - time data transmission, excellent anti - interference ability, and compliance with national standards, has become an ideal choice for high - voltage electrical equipment monitoring. We look forward to working with you to jointly build a safer and more efficient power system.
