Applications
 
  • The leak detector can be used on soils of site-fabricated double-walled flat-bottom tanks according to DIN 4119, and another double-bottoms.
  • To monitor double-walled pipes with a max. operating pressure of 3 bar. Is the installation of pipe elbows or multi storey buildings planned, the suction line must be connected at the lowest point of the pipeline.
  • 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. -450 mbar +/- 15 mbar

Switching values: relative pressure 
Alarm ON PAE = -325 mbar +0/-30 mbar
Pump OFF PPA = -450 mbar +/-15 mbar

For further data please see the data sheet of the V8 leak detector.

 
Operating Conditions
 
  • The media list in the technical description must be observed.
  • The interstitial spaces of the vessels or piping must be suitable for the leak detector.


Accessories
  • Installation of a potential free relay.
  • The leak detector may also be in a protective casing, depending on the application, supplied complete with outdoor heating and alarm. (See product image)
