MCE18/SF6 Pressure Gauge
Brand: Nuova FimaThese instruments are manufactured to monitor the electrical operations on hermetically sealed systems containing Sulphur Hexafluoride gas (SF6).
The indication and the electrical operations are calibrated to the gas density (isochore) according to the relation pressure-temperature.
The M5 model is suitable for indoor installation while the M6 model has been designed for the outdoor installation as well.
The oil filled executions are particularly suitable for installation when vibrations are apparent
