ZMJ100PF Series Density Monitors

Application of ZMJ100PF Series Density Monitors

  • SF6 Gas Insulated Switchgear (GIS)

  • SF6 Insulated Circuit Breaks

  • SF6 Insulated Pole-Mounted Switch

  • SF6 Insulation Transformer

  • SF6 Insulation Mutual Inductor

  • SF6 Insulated Busbar Systems

Features of ZMJ100PF Series Density Monitors

  • Measurement accuracy is higher with the temperature compensator

  • Suitable for indoor or outdoor use

  • Hermetically sealed case of stainless steel AISI 304

  • AISI 316 gas contact parts

  • Specified values and signal outputs regardless of instal altitude

  • Design of an electric contact switch to accurately and stably monitor gas density function SF6

  • Multiple options, such as a pressure alarm, a double alarm or a two-way locking, can be implemented by up to four pairs of points of contact.

  • The overlapping dial design eliminates the cable's gap and prevents the sunlight from entering the metre on the compensation element.
