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
Within the side walls of the enclosure housing there is a short vertical slot and a long
horizontal slot. The short vertical slot is the reference sensor position (REF).
6. Place the spacer bar on the enclosure side wall and insert the screw pin through the REF
hole of the spacer bar.
7. Lower the fixed reference sensor into the enclosure housing and push the sensor back
against the end plate. Then insert the threaded end of the screw pin through the REF
hole in the spacer bar and into the enclosure housing. Make sure sensor does not make
contact with the pipe at this time.
Note
Make sure to align sensor in enclosure housing flush against alignment dimple in end
plate opposite cable end.
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.
8. Mate sensor with pipe.
Note
Do not smear couplant while mating sensor to pipe.
9. Position clamp plate screw assembly into notch and slide over sensor.
