FUNCTION DESCRIPTION
How the LAG 2000 A leak detector system works
The monitoring space of the tanks contains leak detector liquid that is filled up to the
inspection glass of the LDL tank (see
Figure 2
). When the tips of the sensor unit are
submerged in the leak detector liquid, the electrical circuit between the two electrodes of the
sensor unit is closed.
If the tank has a leak, the leak detector liquid flows out. The tips of the sensor unit are no
longer submerged, the electric circuit is interrupted and the display unit shows an acoustic
and visual alarm.
Type LAG 2000 A with relay output:
The relay for an additional alarm is connected.
