ZMJ100PF Series Density Monitors

With a special dial structure, when used outdoors, it can isolate the influence of sunlight on temperature compensation, improve the accuracy of the display, and avoid misoperation of the contacts.

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.
