WARNING! The Model 7xD, 7xR or 7xT overfill probes should be
used for Safety Shutdown/Overfill applications. All other
G
uided Wave Radar probes should be installed so the
maximum overfill level is a minimum of 6" (150 mm)
below the process connection. This may include utilizing
a nozzle or spool piece to raise the probe. Consult
factory to ensure proper installation.
WARNING! Do not disassemble probe when in service and under
pressure.
2.4.1 Installing a Coaxial Probe
(Models 7xA, 7xD, 7xG, 7xP, 7xQ, 7xR, 7xS, and 7xT)
Before installing, make sure the:
• Model and serial numbers on the nameplates of the
ECLIPSE probe and transmitter are identical.
• Probe has adequate room for installation and has unob-
structed entry to the bottom of the vessel. The Model 7xD
(High Temp./High Pressure) probe, Model 7xP (High
Pressure) probe, Model 7xR (Overfill) probe, Model 7xS
(Steam) probe and Model 7xT (Interface) probe require
added clearance. See Physical Specifications, Section 3.6.6.
• Process temperature, pressure, dielectric, and viscosity are
within the probe specifications for the installation.
See Specifications, Section 3.6.
• Model 7xD (High Temp./High Pressure) probes should be
handled with extra care due to the ceramic spacers used
throughout their length.
• Model 7xG (caged GWR) probes should be handled
with extra care. Only handle these probes by the flanges.
2.4.1.1 To install a coaxial probe:
① Make sure the process connection is at least
3
⁄4" NPT or a
flanged mounting.
② Carefully place the probe into the vessel. 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. Do not use sealing com-
pound or TFE tape on probe connection to transmitter as this
connection is sealed by a Viton
®
O-ring.
NOTE: For applications using the Model 7xQ or 7xS steam probes, it
is mandatory to keep the transmitter and probe matched as a
set.
