and remains operational. The components of the electronic circuitry integrated in the
device remain operational even under the temperature loads.
The outcome of mechanical function tests and software tests was positive. Undefined
measured values, faulty calibration and failure of the system clock pulse all cause an
alarm to be triggered. The leak detector of type DLR-... can comply with the
requirements made of it in terms of monitoring the overpressure generated in the
interstitial space and in terms of automatically generating an alarm when the alarm
pressure threshold is reached.
The outcome of the alarm device tests was also positive. After 24 hours of continuous
operation, the acoustic alarm device generated a noise level > 70 dB(A) at a distance
of 1 m with the control cabinet closed. The visual alarm device was deemed to be
adequate.
According to information supplied by the manufacturer, the pressure measuring sensor
is pressure-resistant up to an overpressure of 30 bar, so no impairment of functionality
is anticipated in higher pressure ranges.
The electrical installation in the fittings box is compliant with DIN VDE regulations.
External forwarding of an alarm is ensured via the switching of a potential-free relay,
whereby the device is protected against the circuit of the external alarm and through
an interconnected additional fuse.
The leak detector with the type designation DLR-P... has the same design as the leak
detector DL-... and, during the course of the approval process for obtaining General
Building Authority Approval (
allgemeine bauaufsichtliche Zulassung
for Germany), it
was already subjected to a suitability test. The leak detector DL.. has been granted
General Building Authority Approval (
allgemeine bauaufsichtliche Zulassung
for
Germany) for monitoring of double walled containers (approval no. Z.65.23-409). From
the point of view of the testing body, there are no objections to the use of the leak
detector for monitoring of double walled pipes within the constraints of the application
parameters according to 3.1 and in accordance with the technical description for the
leak detector DLR-P.. dated 21.12.2005. The leak detector is pressure resistant up to a
pressure of 30 bar.
The leak detector with the type designation DLR-GS has the same design as the leak
detector of type DLR-2, as a result of which its suitability has already been verified in
the approval process. The leak detector DLR-2 has already been granted General
Building Authority Approval (
allgemeine bauaufsichtliche Zulassung
for Germany)
under the approval no. Z-65.26-304.
