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

Applications

The leak detector with an explosion protected housing bottom 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 according to DIN 4119.
For connection to double-walled plant or site-made containers, trays or sumps with a general building inspection approval or a laboratory certificate.
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.
DIN 6608 Part 2 containers that were previously monitored by liquid leakage can be monitored with this vacuum leak detector after extracting a specified volume of leakage fluid.
To monitor double-walled, pressure-operated pipelines.
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

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 tanks and/or pipelines.
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.
