Applications
 
  • The leak detector can be used on single-walled tanks with leak protection lining and a suction line to the vessel bottom out.
  • The leak detector can also be used on double-walled tanks with a general building approval (certificate sooner), provided a suction line to the vessel bottom is present. The conditions listed in the technical description have to be followed.
  • For monitoring of water-polluting liquids and flammable liquids with a flash point < 55°C.

The leak detector must be mounted outside the hazardous area (ex-zone)!


Function
 
  • Leak detector on the vacuum principle, with integrated pump.
  • The vacuum pump evacuates air from the interstitial space and blows it through the exhaust pipe to the exhaust valve of the container.
  • Based on the set switching values a trigger switch mounted on the measuring line controls: Pump ON / OFF, Alarm ON / OFF.

Operating vacuum:
in the interstitial space
max. -80 mbar +/- 5 mbar

Switching values: relative pressure 
Alarm ON PAE = -34 mbar +0/-10 mbar
Pump OFF PPA = -80 mbar +/-5 mbar

For further data please see the Technical Description of the "VAKUMATIK IV F R34" leak detector.

 
Operating Conditions
 
  • The media list in the technical description must be observed.
  • The leak protection lining in single-walled tanks must have a general building approval (certificate earlier).
