HM100PR Uhv Sf6 Density Monitor


Application of HM100PR EHV SF6Density Monitor


  • SF6 Gas Insulated Switchgear (GIS)

  • SF6 Insulated Circuit Breakers

  • SF6 Insulated Pole-Mounted Switch

  • SF6 Insulated Transformers

  • SF6 Insulated Mutual Inductor

  • SF6 Insulated Busbar Systems


Feature of HM100PR EHV SF6Density Monitor


  • They adopt highly reliable circuit design, multilevel isolation and filtering technology, effectively preventing conductive interference. 

  • They adopt a full-body shield design, stainless steel shield, shielding junction box and military-grade shielding glass, ensuring anti-electromagnetic radiation interference ability. 

  • They are able to use the backstage of optical fibre communication to prevent the transmission of data by electromagnetic interference. 

  • Using a high-precision SF6 density algorithm, background monitoring data will coincide with the field instructions. 

  • They are fully compatible with standard SF6 remote products; in strong interference occasions they do not need further modifications. 

  • The temperature compensator ensures greater accuracy of the measurement. 

  • Suitable for installation indoor or outdoor. 

  • Overpressure alarm, dual alarm or double locking, and many more solutions up to four switch contacts can achieve safer and more secure monitoring
