2.5 LENS PROBE WITH HULLFITTING MADE OF STAINLESS STEEL
A/ INSTALLATION PROCEDURE
1.
Drill a 184mm hole in the hull. Do an external chamfer of 5mm (45°) for welding.
2.
Position hull-fitting in the correct mounting direction.
The reference mark drawn on hull-fitting is oriented towards bow, it must be exactly
parallel to the vessel axis.
The hull-fitting defines the mounting direction of the lens probe.
When the hull-fitting is welded, grind the external seam on a level with hull surface in order
not to create hydraulic interferences around the probe.
3.
Weld a steel pipe to back of hull-fitting.
Ø = 40mm - Thickness = Minimum 5mm
This pipe will be stopped at 50mm above maximum waterline.
4.
Introduce the probe after pulling watertight cable into the pipe.
5.
Brush probe bottom with watertight rubber before fixing it with its 4 screws.
Caution: DO NOT GREASE THE ELECTRODES.
When using anti-fouling paint, DO NOT PAINT THE ELECTRODES.
B/ DISMOUNTLING AND CHANGING OF SENSOR
1/ Cut off power supply of the electronic.
2/ Disconnect the watertight cable sensor from the electronic.
3/ Strongly attach the watertight cable to a rope of at least the length of pipe.
4/ Send a diver to unscrew the four fixation screws of sensor.
5/ Screw-up the two extraction screws in order to push out the sensor from its hullfitting.
6/ Extract the complete defective sensor with its watertight cable and the rope attached to it.
7/ Strongly attach the new sensor’s watertight cable to the rope and pull back up the cable for
a new connection.
Caution
:
Before replacing the sensor in its hullfitting, don’t forget to apply the
watertight o’ring by silicone mastic.
This equipment is DNV and GL typed approved.
