57-645 Eclipse Guided Wave Radar Transmitter - PROFIBUS PA™

WARNING! The Model 7xD, 7xR or 7xT overfill probes should be

used for Safety Shutdown/Overfill applications. All other

Guided 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.

3.4.1 Installing a Coaxial Probe

(Models 7xA, 7xD, 7xP, 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.

• Process temperature, pressure, dielectric, and viscosity are

within the probe specifications for the installation.

• Model 7xD (High Temp./High Pressure) probes should be

handled with extra care due to the ceramic spacers used

throughout their length.

3.4.1.1 To install a coaxial probe:

x Make sure the process connection is at least 3⁄

" NPT or a

flanged mounting.

y Carefully place the probe into the vessel. Align the gasket

on flanged installations.

z Align the probe process connection with the threaded or

flanged mounting on the vessel.

{ 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.
