57-606 ECLIPSE Model 706 Guided Wave Radar Transmitter
NOTE: For applications using the Model 7yS Steam Probe, it is
mandatory to keep the transmitter and probe matched as a
set. Refer to Section 3.2.5 for additional information regarding
saturated steam applications.
• Probe has adequate room for installation and has unob-
structed entry to the bottom of the vessel.
• Process temperature, pressure, dielectric, and viscosity are
within the probe specifications for the installation. See
Specifications, Section 3.6.
2.4.1.1 To install a coaxial probe:
1. Ensure that the process connection is the correct threaded
or flanged mounting.
2. Carefully place the probe into the vessel. Properly align the
gasket on flanged installations.
3. Align the probe process connection with the threaded or
flanged mounting on the vessel.
4. For threaded connections, tighten the hex nut of the probe
process connection. For flanged connections, tighten flange
bolts.
NOTE: If the transmitter is to be installed at a later time, do not remove
the protective cap from the probe.
NOTE: Do not use sealing compound or TFE tape on probe connec-
tion to transmitter as this connection is sealed by a Viton
®
o-ring.
2.4.2 Installing a Segmented Coaxial Probe
1. Use the large installation plate with the 1.88" slot (provided
with the order) to hold the lower section of the outer tube.
Using two 2" wrenches, tighten couplings. Threads will be
self-locking.
Repeat for the second outer tube section.
2. Use the smaller installation plate to hold the lower section
of the extension shaft, resting one of the spacers on the
plate. Using two
1
⁄
2
" wrenches, tighten extension shaft
coupling. Secure with set screws.
Repeat for the second extension shaft section.
3. Using two
1
⁄
2
" wrenches, attach the middle extension shaft
segment to the top segment (built into the probe head).
The flange gasket should be in place before assembling this
joint. It may be taped to the probe flange to hold it out of
the way.
4. Remove the smaller installation plate from the extension
shaft and assemble the middle outer tube segment to the
coupling on the probe head. Remove the large installation
plate, and assemble the flanges.
