Description
Transducer System
The 3300 XL 11 mm Proximity Transducer System consists of:
l 3300 XL 11 mm probe
l 3300 XL 11 mm extension cable
l 3300 XL 11 mm Proximitor Sensor
The 3300 XL 11 mm Proximity Transducer System has a 3.94
V/mm (100 mV/mil) output for non-contacting vibration and
displacement measurements on fluid film bearing machines.
The large 11 mm tip enables this transducer system to have a
longer linear range compared to our standard 3300 XL 8 mm
Transducer System. It is primarily used in the following
applications where the longer linear range is necessary:
l Axial (thrust) position measurements
l Ramp differential expansion measurements on steam
turbines
l Rod position or rod drop measurements on
reciprocating compressors
l Tachometer and zero speed measurements
l Phase reference (Keyphasor) signals

The 3300 XL 11 mm Proximitor Sensor is designed to replace
the 7200-series 11 mm and 14 mm Transducer Systems. When
upgrading from the 7200-series system to the 3300 XL 11 mm
system, every component must be replaced with 3300 XL 11
mm components. In addition, the monitoring system must
be updated. If using a 3500 Monitoring System, an updated
version of the configuration software that lists the 3300 XL 11
mm Transducer System as a compatible option is required.
Existing 3300 Monitoring Systems may need a modification.
Contact your local sales and service representative for
assistance.
3300 XL 11mm Proximity Transducer System
Datasheet 146256 Rev. K
The 3300 XL 11 mm Proximity Transducer
is designed for measuring position or
vibration within a frequency range of 0
to 8 kHz. Typical applications of this
system include radial vibration and
position, axial position and Keyphasor
measurements.
Although the terminals and connector
on the Proximitor sensor have
protection against electrostatic
discharge, take reasonable precautions
to avoid electrostatic discharge during
handling.
Proximitor Sensor
The 3300 XL 11 mm Proximitor Sensor has the
same advanced features found in the 3300 XL 8
mm Proximitor Sensor. Its thin design allows it
to be mounted in either a high-density DIN-rail
installation or a more traditional panel mount
configuration. Improved RFI/EMI immunity
allows the 3300 XL Proximitor Sensor to achieve
European CE mark approvals without any
special mounting considerations. This RFI
immunity also prevents the transducer system
from being adversely affected by nearby high
frequency radio signals. SpringLoc terminal
strips on the Proximitor Sensor require no
special installation tools and facilitate faster,
highly robust field wiring connections.
3300 XL Probes and Extension Cables can also
be ordered with a FluidLoc cable option. This
option prevents oil and other liquids from
leaking out of the machine through the cable’s
interior. The connector protector option
provides additional protection of the
connectors in a humid or moist environment.
Connector protectors are recommended for all
installations and provide increased
environmental protection2. Additionally, the
3300 XL 11 mm probe comes standard with a
locknut with pre-drilled safety wire holes.
Notes:
1. Proximitor Sensors are supplied by
default from the factory calibrated to AISI
4140 steel. Calibration to other target
materials is available upon request.
2. Silicone tape is also provided with each
3300 XL extension cable and can be used
instead of connector protectors. Silicone
tape is not recommended in applications
where the probe-to-extension cable
connection will be exposed to turbine oil.
Proximity Probe and Extension Cable
The 3300 XL 11 mm probe comes in varying
probe case configurations, including armored
and unarmored ½-20, 5⁄8 -18, M14 X 1.5 and M16 X
1.5 probe threads. The reverse mount 3300 XL 11
mm probe comes standard with either 3⁄8 -24
or M10 X 1 threads. All components of the
transducer system have gold-plated brass
ClickLoc connectors. ClickLoc connectors lock
into place, preventing the connection from
becoming loose. The patented TipLoc molding
method provides a robust bond between the
probe tip and the probe body. The probe cable
is securely attached to the probe tip utilizing
our patented CableLoc design that provides
330 N (75 lb) pull strength.

152 mm (6.0 in)
Measurements on shaft diameters smaller than
76 mm (3.0 in) usually require close spacing of
radial vibration or axial position transducers
with the potential for their electromagnetic
emitted fields to interact with one another
(cross talk), resulting in erroneous readings.
Care should be taken to maintain minimum
separation of transducer tips, generally at least
64 mm (2.5 in) for dual axial position
measurements or 54 mm (2.1 in) for radial
vibration measurements to prevent cross talk.
Radial vibration or position measurements on
shaft diameters smaller than 152 mm (6.0 in)
will generally result in a change in scale factor
due to the curvature of the shaft surface.

3300 XL probes are designed to seal
differential pressure between the
probe tip and case. The probe sealing
material consists of a Viton O-ring.
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
It is the responsibility of the customer or
user to ensure that all liquids and gases
are contained and safely controlled
should leakage occur from a proximity
probe. In addition, solutions with high or
low pH values may erode the tip
assembly of the probe causing media
leakage into surrounding areas. Bently
Nevada, LLC not be held responsible for
any damages resulting from leaking
3300 XL proximity probes. In addition,
3300 XL proximity probes will not be
replaced under the service plan due to
probe leakage.
