■ Product Overview

The EGD Series is a digital gas density transmitter designed for accurate monitoring of SF₆ (Sulfur Hexafluoride) gas density used in gas-insulated electrical equipment.

Unlike conventional mechanical temperature-compensated gas density gauges, the EGD Series incorporates both pressure and temperature sensors and performs software-based temperature compensation using an internal digital algorithm.

By continuously calculating the actual SF₆ gas density regardless of ambient temperature variations, the transmitter provides highly accurate and reliable density monitoring.

It is ideally suited for GIS, circuit breakers and other gas-insulated electrical equipment requiring continuous condition monitoring and preventive maintenance.

 

■ Application Industries

The EGD Series has been developed through extensive performance verification and reliability testing for demanding industrial environments, ensuring long-term stable monitoring of SF₆ gas density.

Its software-based density compensation minimizes measurement errors caused by temperature variations, making it suitable for critical power transmission and distribution applications.
