PI Depth sensor
Purpose
The PI Depth sensor monitors the current depth of the net, as
well as the rate of any depth changes. All measurements are
related to the surface.
(A) = Two Depth sensors are mounted to the ground rope to
monitor the depth.
(B) = One Bottom Contact sensor is mounted to the ground rope
to detect if the net hits the bottom.
Main parts
(A) = Negative charging / fastening lug
(B) = Positive charging / fastening lug
(C) = Communication link
(D) = Location of sensor lamp
(E) = Water switch sensor
(F) = Pressure sensor (label is removed)
Daily operation
Once installed and put to use, the sensor will
automatically be switched on once the
waterswitch is activated. After an initial startup,
the sensor starts transmission of the current depth
when this exceeds a predefined depth you have
selected. When the sensor is not in use, check that
the sensor lamp (D) is not flashing from time to
time, as this indicates that the sensor is on and is
discharging its batteries. In this case, wash the
sensor in fresh water to r emove salt and dirt.
