Applications
 
  • The wetted parts of the leak detector V33 are made of stainless steel. The wide application range of the possible bearing fluids is given in the standard DIN 6601.
  • The leak detector can be used on double-walled tanks according to DIN EN 12285-1 (DIN 6608 Part 2), DIN EN 12285-2 (DIN 6616 Form A), DIN 6618 part 2 / 4, DIN 6619, Part 2, DIN 6623 part 2 and DIN 6624 part 2 as well as on flat bottom tanks to DIN 4119.
  • The leak detector can also be used to monitor single-walled tank with a leak protection lining, if it is approved for the values noted below.
  • For monitoring of water-polluting liquids and flammable liquids with a flash point > 55°C.
  • The storage medium may only have the density allowed for the container type.

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


Function
 
  • Leak detector on the vacuum principle, with integrated vacuum pump.
  • Integrated potential-free relay.
  • 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 V33 leak detector.

 
Operating Conditions
 
  • Leak fluid must not be present in the interstitial space.
  • The interstitial spaces of the vessels must be suitable for the leak detector.


Accessories
  • The leak detector may also be mounted in protective casing, supplied complete with or without outdoor heating. (See product image)
  • Mounting Kits (MBS) for the corresponding container connections.
