SLG726
The inner rod is comprised of 2.0m rod segments and one rod end. Depending on the
length of the probe there may be 0 to 3 2.0m rod segments. As with the rod probe, the rod
segments are attached to each other by way of a stud and lock washer. In the coaxial
probe construction a spacer is placed at each joint, retained by the lock washer. Because
the spacers have closed sections, they must be slipped over the end prior to connecting
the following rod segment. If the coaxial probe is 2.0m or shorter it will come with a
single outer tube. If the probe length is longer than 2.0m, the outer tube will be supplied
in segments. There are three types of outer tube segments:

Starter segment: which has an internal thread to attach to the process connector,

Extension segment: which had external threads on both ends,

End segment: which has and external thread on one end.
Probes over 2.0m in length will always have one "starter" and one "end" segment, along
with 0 to 2 extension segments in between. The tubes are connected to each other by way
of a threaded tube coupler. It is recommended to build the coaxial probe 2m at a time.
That is, attach one 2.0m rod segment and then place the tube over the rod. Slip a spacer
onto one of the ends of the rod and attach the next rod segment. Repeat until the probe is
together.
Tip: To ease assembly, construct the coaxial probe vertically, by suspending the
transmitter by the process connector on a hoist or crane.
Refer to Figure 3-9 for the SLG726.
