8774 Gas Density Sensor with analogue and PWM output - Trafag AG

Density Sensor for sf 6 and other gases The Trafag gas density sensor type 8774 was specifically designed for monitoring insulation gases. The gas density is measured with an oscillating quartz with excellent long term stability. The constant resonant frequency of a quartz oscillator under vacuum is compared with the resonant frequency of an identical quartz situated in the sample gas.Get price

Sulfr hexafluoride Gas Density Monitors | TRAFAG

The Gas Density Monitor functions on the principle of reference gas comparison and therefore does not require temperature compensation. It is much more accurate than bimetal compensated pressure gauges and it is extremely vibration and shock resistant.Get price

Gas density of sf 6 and other gases - Trafag AG

Gas density. Trafag gas density sensors are monitoring the insulation gas (e.g. sulfurhexafluoride SF 6) and thus ensure the safe operation of countless power plants and high voltage switching installations.Get price

Trafag Sulfr hexafluoride Air Sensor leak testing for transformers

Trafag insulating gas Air Sensor leak testing for transformers Obviously, for the GIS operator, it is useful to detect SF 6 leaking into the oil tank as a first step toward localizing and repairing the leak. Also, SF 6 in the oil can complicate the Dissolved Gas Analysis (DGA) processes that are so important to transformer health assessment andGet price

Gas Density Sensors | TRAFAG

Electronic insulating gas gas density monitoring with patented quartz tuning fork The Gas Density Sensor uses a quarz tuning fork to sense gas density directly – a unique technology patented by Trafag. With the delivery of continuous output signals (analogue or digital) from this electronically operating sensor, Trafag opens new paths for the energyGet price

Sulfr hexafluoride Gas Density Monitoring | TRAFAG

Trafag gas monitoring devices measure the gas density directly, i.e. gaz sf6 Gas Density Monitor s, with the unique gas density reference principle or the patented quartz tuning fork technology, i.e. gaz sf6 Gas Density Sensor s, or by combining both principles, i.e. Sulfr hexafluoride Hybrid Gas Density Monitors. They thus offer the most reliable solution on the market by directly measuring the sf 6 gas density.Get price

Hybrid insulating gas Gas Density Monitors | TRAFAG

The Hybrid Gas Density Monitor combines the advantages of both the mechanical gas density monitorand the electronic gas density sensor in a compact all-in-one apparatus: With its analogue or digital output it is the ideal gas density monitor for smart online sf 6 gas management systems. It also has a local gas pressure indication and alarm contacts.Get price

Sulfur hexafluoride - Wikipedia

Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of 6.12 g/L at sea level conditions, considerably higher than the density of air (1.225 g/L). It is generally transported as a liquefied compressed gas.Get price
