Summary
IPOWER gas pressure density meter can be used in conventional or even extreme harsh environment, for the low density of gas in the equipment, stable output alarm signal to avoid danger. The alarm contact will alert the operator in the background when the gas pressure value drops to the set alert position due to leakage.
Application
Gas density monitoring of closed SF6 tanks
SF6 circuit breakers
Ring network cabinets
Column switches
Transformer
Feature of SF6 gas density pressure switch
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.
