Sensepoint XCD RTD Technical Manual SPXCDHMRTEN Issue 1

To mount the Sensepoint XCD transmitter to a Vertical or Horizontal pipe/structure, use

the optional XCD Mounting Kit and following procedure:

1. Fit the four spring washers, then the plain washers to the M8 x 80mm SS316 bolts.

2. Pass the four bolts through the four mounting holes of the transmitter housing.

Note:

If the XCD sunshade is to be used then fit the sunshade and the two locking

bolts and washers to the M8 x 80 bolts.

4. Place the transmitter housing against the mounting position and fit the two “U”

channel mounting bars the other side of the Pipe/Structure.

5. Secure bolts to the threaded holes of the “U” channel mounting bars.

6. Tighten the four bolts securely, (but do not over-tighten) until the transmitter housing

cannot be moved by hand on its mounting position.

Note: For further details of installation please see section 17.
