ASF LEAK DETECTOR TYPE V90 – Version “N” - VACUUM PRINCIPLE

Applications

The leak detector with an explosion protected housing bottom can be used on double-walled tanks with a suction line down to the vessel bottom.
The leak detector can also be used to monitor single-walled tanks with a leak protection lining, if this is approved for the values noted below.
For monitoring of water-polluting liquids and flammable liquids with a flash point < 55°C, the explosion group IIA (IIB as an option) and the temperature class T4 are assigned.
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)!

Operating Conditions

Approved leak protection lining with general building inspectorate approval.
No leak detection fluid is allowed in the interstitial space.
Compliance with the relevant explosion protection guidelines for liquids with flash point < 55°C
The leak detector must be mounted outside the hazardous area (ex-zone)!

Accessories

Mounting Kits (MBS) for connection to containers.
For the extended field of application, these leak detectors are built alternatively in stainless steel.

Function

Partially explosion protected leak detector on the vacuum principle, with integrated vacuum pump, consisting of:
Combined with a housing upper part (SK) and bottom (AK). Within the cluster housing, the ex-zone separation was made, so that the leak detector is suitable for the control of flammable liquids.
With built-in potential-free relay.
In the lower part of the housing a detonation fuse is fitted in the intake and exhaust pipe by standard.
