SF6 Gas Density Monitor Working Mechanism:
Density Relay is composed of the density detection system including pressure sensing elements a drive mechanism, temperature compensation elements, an indication unit and an electric contact unit.
it uses the pressure measuring principle with temperature compensation to measure the pressure of the SF6 gas under certain density in the sealed vessel for field test and control through a density detection system thus achieves the goal of Gas Density monitoring.
In a sealed vessel.the pressure of SF6 gas under certain temperature(20C)can be seen as the gas density under this temperature (20C) We take the SF6 gas pressure value under 20C as the representative value of its density and also as the scale value.When the ambient temperature chandes. the temperature compensation elements will compensate for the aas pressure change caused by the temperature change.Therefore,as long as the SF6 gas density remains unchanged,the indication value of the density meter will keep the same.
When SF6 gas is filled into the sealed vessel or the gas changes,pressure sensing elements wil make displacement which is converted into the indication value through the drive mechanism.When the ambient temperature change induces the indication value change,the temperature compensation elements will make compensation and correction.
In the electric contact unit.when SF6 gas density lowers to certain preset valuecorrect and reliable alarm or lock control signals will be sent out to ensure normal and safe operation of the electric equipment.

SF6 Gas Density Monitor Features
1. Electric contact switch design realizes accurate and reliable SF6 gas monitoring functions.
2. With temperature compensation, the compensation performance is stable and the detection precision is high.
3. On-site display values and output contact signals are not affected by external conditions including the altitude and ambient temperature change.
4. Core elements are made of imported materials with high precision.
5. Good shockproof performance.
6. There are three contact groups at most, which can realize several options including overpressure alarm, double alarm or double lock and make the monitoring safer and more reliable.
7.Gas fill, micro-water test and calibration can be implemented without removal of the SF6 gas density relay, making it easy for on-site staff to conduct micro-water test and gas supplementand avoiding the seal face and seal ring damage arising from removal.
8.304 stainless steel is adopted for the sealed case, which prevents both moisture and corrosion.
