SF Maintenance Equipment Fundamentals

sensor used in a hygrometer should be capable of handling arced SF 6 and should not require that the gas be pre-filtered. It is extremely important to exclude moisture from any system employing SF 6 as a dielectric. Moisture can react with SF 6 under the influence of electrical discharges to form toxic and corrosive compounds.Get price

NDIR SENSORS FOR Sulfr hexafluoride MEASUREMENT

Sulfr hexafluoride (sulphur hexafluoride) is a non-com- bustible and non-toxic gas. Throughout the world it is used primarily for insulating electrical high-voltage switching systems, transformers and cables. It is also used as an etching gas in semiconductor produc- tion and as a tracer gas in environmental simulations. The sensors measure either the purity and quality of the insulating gas in the systems or reliably detect minute gaz sf6 quantities in indoor air.Get price

Bad Mass Air Flow Sensor? (7 Symptoms with Fixes) | The Motor Guy

A bad mass air flow sensor won’t reliably measure the amount of air coming in through the air filter, resulting in a delay in the fuel delivery during sudden acceleration and a temporary lack of power. In such a scenario, the ECU will sense the drop in engine vacuum first and then using other sensors, will decide if more fuel is required.Get price

The Symptoms of a Bad Mass Air Flow Sensor - AutoZone

The mass air flow (MAF) sensor, part of your vehicle’s electronic fuel injection system, is responsible for calculating the total amount of air entering the engine. A faulty MAF sensor can cause your vehicle to run too rich or run too lean. You’ll notice if the tailpipes eject black smoke or when the engine runs rough or backfires.Get price
