PI Height sensor
Purpose
The
PI Height
sensor monitors the
current height of the trawl, as well
as the rate of any height changes. All
measurements are related to the bottom.
(A) = The PI Height sensor is normally mounted on the headrope, and by means of the
built-in echo sounder it will measure the distance to the bottom.
(B) = Echo sounder transmission field
Daily operation
Once installed and put to use, the Height
sensor will automatically be switched
on once the waterswitch is activated.
After an initial startup, the sensor starts
the echo sounder, and the depth results
are transmitted to the vessel. When the
sensors are not in use, check that the
sensor lamp (D) do not flash 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
remove salt and dirt.
If you operate with
Fast
update rate, the
sensors must be charged approximately
every 35 hours. Used with
Normal
or
Slow
update rates, the operational
life is approximately 60 or 250 hours
respectively. The optimal sensor charging
temperature is from +10 to +25° C. The
sensor can only be charged with the

Note: Charging sensors at sub-zero
temperatures can create explosive
gasses. Simrad assumes no liability for
the improper charging of sensors or the
use of chargers not specified in Simrad’s
sensor charging documentation.
