WIKA Gas Density Monitor (GDM-063)

With gas filling


  • Medium-voltage equipment
  • Gas density monitoring of closed SF6 gas tanks
  • Raising an alarm when defined limit values have been reached

Special Features

  • Case and wetted parts from stainless steel
  • On-site display with switch contact
  • Temperature-compensated and hermetically sealed, therefore no influence of temperature fluctuations, differences in level and atmospheric pressure fluctuation
  • Compensation possible for gas mixtures
  • Traceability by serial number

Gas density is a crucial operating parameter for mediumvoltage switchgear. If the required gas density is not present, safe operation of the plant cannot be guaranteed.

The WIKA gas density measuring instruments provide reliable warnings against dangerously low gas levels, even under extreme ambient conditions. Electrical switch contacts warn the plant operator when the gas density drops below defined levels due to leakage.

Numerous application areas
The WIKA gas density monitor is hermetically sealed and temperature-compensated. Measured value fluctuations and erroneous alarms caused by changes in either ambient temperature or atmospheric pressure are therefore prevented.

Via the on-site display, the pressure can be read directly on the instrument with reference to 20 °C [68 °F]. With the integrated switch contacts, simple switching tasks can be realised quickly and without complication.
