100mm Center Back Density Monitor,SF6 Electronic Densimeter Gas Leak Test Manometer

Description: SF6 Density Monitors are an economical and reliable way to monitor SF6 gas density and leakage over a wide temperature range. These instruments are used to monitor SF6 gas density in sealed tanks. They are applied to indicate gas density and to provide a signal outputs when the...

Product Details


SF6 Density Monitors are used for monitoring and controlling the density of the protective gas SF6 in high voltage power equipment.It is widely used in high voltage circuit breakers, medium voltage switches, gas insulation equipment (GIS), high voltage cables, transformers and transformers. 

It is a  spare part suitable for outdoor harsh environment. It can timely issue an alarm signal, latch signal or overpressure signal in case of the emergence of SF6 gas leakage to ensure the safe operation of electrical equipment.
