Height/Depth measurements and sensors
The purpose of the height/depth dual measurement is to simultaneously check both the water depth and the distance from the sensor and down to the bottom.
Tip
The Height/Depth sensor view was provided exclusively for the Simrad PI SeineSounder sensor. You may however set up one PX MultiSensor to do the same measurements, and then use this sensor view.
The Simrad PI SeineSounder sensor contains both a pressure sensor to measure the water depth, and a small echo sounder to measure the height above the bottom.
It has been developed to be used on both bottom and pelagic trawls, as well as on purse and Danish seiners. The sensor must be installed in two different ways depending on the application. On a trawl, it is mounted horizontally behind the headrope. On a purse seine, it is mounted vertically below the footrope.
Important
In order to provide the two Simrad PI SeineSounder applications and mounting methods, the echo sounder inside the sensor has been equipped with two transducers. By means of a “sensor key” you can easily define which transducer to use.
•  Trawl: Use the short bolt
•  Purse seine: Use the long bolt
Provided with the sensor is a “gift box” with two sensor keys. These are two special bolts, and by means of magnetism inside the bolts, these will select which echo sounder transducer to use. The bolts will also act as water detectors, and that means that they will slowly disintegrate. When you mount the sensor on a trawl or a purse seine, it is therefore important that you use the correct key:
With the PI and PS Depth sensors, three depth versions are available. These are set up for maximum depth 300 m, 600 m or 1000 m. The depth range is fixed by the factory, and can not be changed in the PI Configurator utility. The Simrad PX MultiSensor is set to a fixed 1000 meters range.

The following Simrad catch monitoring sensors can be used to measure both depth and height simultanously:
•  PI SeineSounder
•  PX MultiSensor
Important
The PX MultiSensor must be equipped with a dedicated lid to make this measurement.
About the Simrad PX MultiSensor
Graphic
The Simrad PX MultiSensor is a multi purpose catch monitoring sensor. It is designed to make several different measurements, but only two at the time.
Important
To charge this sensor, use the Simrad PX Charger.
Unless you can use the default communication and measurement parameters programmed by Simrad, you must set up the following important parameters to match your system setup:
•  Communication channel
•  Type of measurement(s) to make
To do this, use the PX Configurator program, or ask your authorized dealer to do it for you.
Note
The Channel Number parameter is vital. The communication channel number you choose here must comply to the channel number programmed into the sensor. If these do not match, the communication will not work. By default, the channel number will match the factory setting.

This is a dual purpose Simrad catch monitoring sensor. It is designed to do two measurements simultanously. Both are fixed, and they can not be changed. This sensor will seize two communication channels on your PI50.

To charge this sensor, use the Simrad PI Charger or the Simrad PI MaxiCharger.
Unless you can use the default communication parameters programmed by Simrad, you must set up the following important parameters to match your system setup:
•  Communication channel
•  Update rate
To do this, use the PI Configurator program, or ask your authorized dealer to do it for you.
Note
It is very important that the Channel number and Update Rate parameters defined for each sensor in the Select Sensors dialog box matches the corresponding parameters programmed into the sensor. If these vital parameters do not match, you will not receive information from the sensor.
The Channel number must be unique for each sensor in simultaneous use.
