The KDWS-ZX is an advanced SF6 micro-water and density online monitoring system integrating new remote sensing and computer technologies. It uses imported high-stability sensors for precise measurements, with built-in circuit correction and compensation to ensure linear output and high accuracy. The system features a sealed, waterproof, and dustproof design, suitable for high-frequency electric field and outdoor environments. It supports RS-485/CAN communication for real-time data upload to a control center, with automatic alarm and interlocking functions for over-limit conditions. Backend software stores historical data and generates trend graphs, facilitating predictive maintenance and smart grid integration.
