SF6 Gas Density Monitor Types

SF6 Gas Density Monitor is mainly used in the power industry. It is matched with sulfur hexafluoride high-voltage circuit breaker, transformer, combined apparatus (GIS), ring network cabinet, inflation cabinet and other equipment. SF6 gas density gauge is used to monitor the gas density in the equipment air chamber (i.e. the pressure at 20 ℃) and can send alarm, locking and other switching signals when the gas density drops to the specified value due to equipment leakage.

ABB offers various SF6 gas density monitors, including models like the GMS600, which uses a transducer for online measurement. These monitors help detect leaks and monitor the overall performance of equipment using SF6 gas, which is crucial for the proper functioning of high-voltage circuit breakers. ABB's SF6 gas density monitors are designed to provide a reliable and maintenance-free solution for ensuring the integrity of gas-insulated systems. 

Here's a more detailed look at some of ABB's SF6 gas density monitoring solutions:

1. GMS600:

• Online Measurement: The GMS600 is equipped with a transducer to measure SF6 gas density online.
• Algorithm: It uses an algorithm to calculate the actual SF6 gas density.
• Monitoring and Trending: The GMS600 is designed to monitor and trend SF6 gas density, helping detect potential leaks and other issues. 

2. Hybrid Gas Density Monitors:

• Self-Acting Monitoring and Continuous Measurement:

These monitors combine self-acting monitoring with continuous density measurement.

• Digital Output:

They offer a digital RS485/Modbus output for communication and data analysis.
