The following unit variants are used:
Overpressure leak detector DLG ..
The leak detector can be operated with air as well as with inert gas as leak
detection medium. The necessary operating pressure in the interstitial space is
generated by pressure-controlled refilling from a stationary pressure
accumulator connected to the interstitial space. If the operating pressure in the
interstitial space falls below the adjusted alarm value, then the visual and
audible alarm is triggered automatically.
Overpressure leak detector DL ..
In this version, pressure is generated in the interstitial space by an integrated
pump, using only dried ambient air as leak detection medium.
All unit variants are equipped with a test coupling for connecting an external
measuring gauge.
Overpressure valves to protect the interstitial space from excessive
overpressure are an integral part of the leak detectors and installed in the
pressure lines of the unit. Overpressure valves to protect the type DLG .. units
when connected to an external pressure accumulator must be connected
externally between the leak detector and pressure accumulator, as required.
