Bently Nevada Machinery Condition Monitoring
Description
The design of the PROXPAC XL Proximity Transducer Assembly
is similar to our 31000/32000 Proximity Probe Housing
Assemblies. The assembly offers the same advantages and
features as the 31000 and 32000 housings for accessing and
externally adjusting proximity probes. However, the housing
cover of the PROXPAC XL Assembly also contains its own 3300
XL Proximitor sensor. This design makes the PROXPAC XL
Assembly a completely self-contained proximity probe
system, and eliminates the need for an extension cable
between the probe and its associated Proximitor sensor. It
also eliminates the need for a separate Proximitor housing, as
the field wiring connects directly between the monitors and
PROXPAC XL Assemblies.
The PROXPAC XL housing is made of Polyphenylene Sulfide
(PPS), which is an advanced, molded thermoplastic. This
material replaces the steel and aluminum in previous
housings offered in the Bently Nevada product line. It also
incorporates glass and conductive fibers in the PPS to
strengthen the housing and more effectively dissipate
electrostatic charges. The PROXPAC XL housing is rated for
Type 4X and for IP66 environments and provides extra
protection in severe environments.

76.2 mm (3.0 in)
When gapped at the center of the
linear range, the interaction
between two separate transducer
systems (cross-talk) will be less
than 50 mV on shaft diameters of
at least 50 mm (2.0 in) or greater.
Care should be taken to maintain
minimum separation of
transducer tips, generally at least
40 mm (1.6 in) for axial position
measurements or 38 mm (1.5 in)
for radial vibration
measurements to limit cross-talk
to 50 mV or less. Radial vibration
or position measurements on
shaft diameters smaller than 76.2
mm (3.0 in) will generally result in
a change in scale factor. Consult

100% condensing, non-submersible
when connectors are protected.
When properly sealed, moisture
should not enter the housing. Users
should take precautions to prevent
moisture from traveling through the
conduit into the housing.
(Specification not guaranteed) Brief
periods (up to one week) of contact
with hot water 95 °C (203 °F) and/or
condensing steam should not
significantly affect the strength of the
plastic housing. Longer contact with
hot water or steam may weaken the
plastic housing during the first 6 to 8
weeks of exposure and ultimately
reduce the housing strength to
approximately half of the initial
value. Tests of actual housing
performance after contact with hot
water and condensing steam have
not been conducted.
The PROXPAC XL design seals
differential pressure between the
probe tip and the housing main
body when used with a 3300 XL 8
mm probe. The sealing material
inside the probe case consists of a
Viton O-ring, whereas the O-ring
between the sleeve and the housing
is Neoprene The plastic housing
design is certified to seal against
hose-directed water according to
Type 4X and IP66 standards but will
not resist internal or external
pressure. Probes are not pressure
tested prior to shipment.
Contact our custom design
department if you require a test of
the pressure seal for your
application.
Exposing the probe to
temperatures below –34 °C
(-29 °F) may cause
premature failure of the
pressure seal.

It is the responsibility of the customer or
user to ensure that their installatin will
contain and safely control all liquids and
gases should the PROXPAC XL
transducer leak. Solutions with high or
low pH values may erode the tip
assembly of the probe, causing media
to leak into surrounding areas. Bently
Nevada LLC will not be held responsible
for any damages resulting from leaking
Proximity Probe Housing Assemblies. In
addition, PROXPAC XL transducers will
not be replaced under the service plan
due to probe leakage.
