Procedure

Saturated steam application is available with SLG726 rod and coaxial probes. The retrofit kit comes
with a nut, a steam reference rod, a stud and two washers. Prior to installing the saturated steam
hardware, the current SLG726 probe needs to be trimmed to maintain the same overall probe length
after the saturated steam hardware is installed. Whether the probe type is rod or coaxial, only the rod
(inner rod for coaxial probe) needs to be trimmed. The following instructions detail the probe
trimming and hardware installation procedures.
Step – 1: Turn off transmitter power.
Step – 2: Remove transmitter from installed location.
Step – 3: For coaxial probes, depending on the length of the coaxial probe, the outer tube may be
constructed from a single length of tube or be assembled using several tube segments joined to
each other using tube couplers. Remove the retaining ring and the end spacer from the end of the
tube. If the probe is under 2.0 m in length, it will be secured to the process connector by an
internal thread. Use a 60 mm wrench to hold the process connector by its flats and a pipe wrench
to unscrew the outer coaxial tube. If the probe is over 2.0m in length, starting from the end
segment, loosen the two M3 set screws holding the couplers in place and then use two pipe
wrenches to unscrew the tubes from the coupler.
