Introduction
INTRODUCTION
Efficient fishery with trawl and purse seine assumes professional
and adequate instrumentation on the gear. Simrad has provided
professional instruments for fish finding for more than sixty years.
This user manual described installation, use and maintenance of
the PI Spread/Depth sensor when put to use w ith the PI catch
monitoring systems.
Purpose and applications
The purpose of the PI Spread/Depth sensor is to achieve accurate
measurements of both the water depth and the distance between
the two trawl doors. The PI Spread/Depth thus contains both
a pressure sensor to measure the w ater depth, and a sensor to
measure the distance to the Remote sensor on the other trawl
door. The results from these measurements are transmitted by
acoustic signals to the PI catch monitoring system mounted on
the vessel.

Simrad PI Spread/Depth
Note
Each Spread/Depth sensor can be configured to communicate
with one of two Remote sensors; Remote 1 or Remote 2. Label
the Spread/Depth sensor accordingly, and ensure that you only
use the sensors in the correct pairs.
The PI Spread/Depth has been developed to be used on both
bottom and pelagic trawls. The sensor is normally installed on
the port trawl door using an adapter.

Simrad PI Spread/Depth
INSTALLATION
The PI Spread/Depth sensor is mounted on the port trawl door
using a special adapter. From this position, it will communicate
with a Remote or a Remote/Depth sensor on the starboard trawl
door.
Sensor installation
The PI Spread/Depth sensor and the Remote or Remote/Depth
sensors must be mounted in dedicated adapters on each trawl
door. These adapters must be installed beforehand. Detailed
information on how to install the adapters are provided with the
installation kit.
The PI Spread/Depth sensor is mounted on the p
ort door, w hile
the Remote or Remote/Depth sensor is mounted on the s
tarboard
door.
Note
It is essential that there is a clear line of sight between the two
transverse communication “eyes” (one on each sensor), and
between the top of the Spread/Depth sensor and the hydrophone
on the vessel.
The two rubber inserts provided at t he bottom of each sensor
adapter must not be replaced with any other t ypes or designs.
It is essential that these inserts provide a secure cradle for the
sensors, but they must also allow for free water circulation to
allow the sensor’s water switch to engage. Also, the design of
the inserts allows sand and m ud to flow out when the trawl doors
are pulled up from the water.
Adapter installation
The installation of the sensor adapter is described in the dedicated
instruction manual provided with the adapter. The document can
also be downloaded from w
ww.simrad.com.
