A The PI Geometry sensor is mounted at the exact centre of
the headrope or footrope.
The two Mini-R responders are mounted on each trawl door
B
or trawl wing.
Each of the two Mini-R responders communicate with the
C
PI Geometry sensor to measure the distances.
D The PI Geometry sensor uses an acoustic link to transmit
the results from the distance measurements to the PI system
on the vessel.
Two sets of PI Geometry sensors with corresponding Mini-R
responders can be used simultaneously.
Note
Each PI Geometry sensor can be set up to communicate with one
of two sets of Mini–R responders; number 1 and 3 or number
2 and 4. Make sure that the PI Geometry sensor is labelled
accordingly, and ensure that you only use the sensor with the
correct pair of responders.
