Product Introduction

The all - electronic SF6 density relay is used to monitor the density of SF6 gas in a closed container. It can display the density change trend through a dynamic curve, estimate the gas - filling time, and has a recovery rate measurement function. When the density value reaches the set value, it outputs an electrical contact signal. At the same time, it can remotely transmit data such as density, leakage rate, and early warning signals in real - time to achieve the function of online remote monitoring.

Main Features

1. The all - electronic SF6 density relay can dynamically and real - time monitor the pressure, temperature, and density of SF6 gas in the gas chamber.

2. Data curve display for intuitive understanding of the dynamic trend of the gas chamber.

3. Calculation of leakage rate to estimate the gas - filling time.

4. The all - electronic SF6 density relay has a temperature compensation function and high measurement accuracy.

5. It has a recovery rate measurement function.

6. Data remote transmission via ModBus protocol
