SF6 Pressure gauges with hose

For precise pressure control in gas compartments

3-558-R001
Indication range: 0 - 10 bar

3-558-R002
Indication range: 0 - 1,000 kPa

The digital SF6 gas pressure gauge allows precise determination of pressure in gas compartments.

The connecting hose for measuring devices is equipped with a self-closing coupling so that no SF6 gas can escape into the atmosphere during the testing process. The device can be transported comfortably and safely in the handy plastic case.

FAQ

What pressure is SF6 filled to in?

The pressure of SF6 gas inside  of any GIE or GIS is dependent on the specifications of the Original Equipment Manufacturer (OEM ). Therefore, we always recommend to "Fill to OEM Specification". In the United States, pressure is typically indicated in PSI but in Europe and Canada, for example, they use Bar.

What is the density of SF6 gas?

SF6 gas density is the mass of the gas occupying a certain volume at a specified pressure and temperature. With that said, if the temperature is higher, you would need to fill to a higher pressure of SF6 gas to achieve the same density than you would if the temperature were lower. The OEM will typically provide a gas density curve on the GIE/GIS to determine the exact PSI to fill to based on the temperature.

Does temperature affect SF6?

Temperature does affect the pressure within a given volume. The density of SF6 remains the same, however, unless one adds or removes gas. Some GIS/GIE are equipped with temperature compensated gauges that account for the temperature of the gas so you only have to fill to the value on the gauge and do not have to account for ambient temperature. A density monitor is another is another device that can also be made temperature-compensated, and will alarm of the gas density drops below a set threshold.
