  Область применения

  The Ex purging unit MiniPurge FM is used to monitor the pressure during continuous purging of an analyzer with purging or inert gas. If the pressure falls below the set value, an optical display is triggered and the relay is activated. This monitoring unit is driven by the purging gas pressure and therefore does not require an additional power supply.
