Sensor installation - Dual enclosure direct mount

Installation Procedure
1. Thread unterminated cable through first enclosure housing grommet and terminate cable
end with F connector and cable gland assembly. For sensor cable selection refer to
Technical data (Page 81). For sensor assembly instructions refer to Sensor wiring
(Page 48).
2. Fill connector end with Super Lube prior to connecting. Install sensor cable.
3. Apply Super Lube to the internal threads at the large end of the thread connector.
4. Attach cable to sensor and then attach cable gland and screw on.
5. Take either sensor and apply a continuous lengthwise 3 mm (1/8-inch) bead of coupling
compound across the center of the sensor emitting surface.
Note
Be careful not to catch or compromise the yellow insulating tape while inserting the
sensor. The insulating tape is used to insulate metal components of the sensor for
cathodically protected pipe.
6. Align sensor in enclosure housing flush against alignment dimple in end plate opposite
the cable end.
7. Mate sensor with pipe.
Note
Do not smear couplant while mating sensor to pipe.
