Pressure leak detector pipeline gas (DLR-G) based on nitrogen with 2 bar alarm pressure and 4,5 bar minimum test pressure of the interstitial space
for above and underground double-walled pipes
with digital manometer (M)
with service indication (Si) indicates the due and prescribed functional test depending on the set maintenance/service interval (time period adjustable between 1 and 63 months)
For the monitoring of water-polluting liquids, whose (possible) explosive vapor-air mixtures (also those that can be formed through the stored/conveyed liquids in contact with air, humidity, condensation or the materials used) must be classifiable into gas group II A to II C as well as in the temperature code T1 to T4. In case compressed air is used as leak detection medium, restrictions regarding explosion protection and permeation of the inner pipe wall must be observed..
