Transmitter/Probe Assembly
Transmitters with probes up to and including 12 inches
(305 mm) in length are shipped pre-assembled. All other
transmitters are shipped unassembled to avoid damage
during transit. These transmitters must be assembled prior
to mounting. Choose your particular configuration from
the following sections and follow the instructions carefully.
2.4.1 Installing a Rigid Probe
Before installing, ensure the:
• Probe has adequate headroom for installation and has
unobstructed 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
.
To install a probe:
x
Make sure the process connection is at least
3
⁄
4
" 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.
{
Tighten the threaded probe process connection using
only the flats on the probe.
Caution:
Packing glands used on all Magnetrol rigid probe assem-
blies have been sealed at the factory under controlled
conditions. Care must be exercised when installing probe
assemblies to avoid breaking the pressure tight gland
seal, which destroys the seal.
2.4.2 Installing a Flexible Probe
Caution:
Flexible probes are shipped with the cable clamp and the
packing gland nut hand tightened. The end of a flexible
probe MUST be kept taut by attaching the anchor end at
the bottom of the vessel or by using a Magnetrol supplied
probe weight.
Caution:
Do not discard the Mylar housing insulator.
Caution:
The probe cable must not be in contact with any metallic
surface in its final installation position.
