The 3300 XL 8 mm Proximity Transducer System consists of:
One 3300 XL 8 mm probe,
One 3300 XL extension cable
One 3300 XL Proximitor
The system provides an output voltage that is directly proportional to the
distance between the probe tip and the observed conductive surface and can
measure both static (position) and dynamic (vibration) values. The system’s
primary applications are vibration and position measurements on fluid-film
bearing machines, as well as Keyphasor* reference and speed measurements3.

Sensor2.
The 3300 XL 8 mm system delivers the most advanced performance in our eddy
current proximity transducer systems. The standard 3300 XL 8 mm 5-metre
system also fully complies with the American Petroleum Institute’s (API) 670
Standard (4th Edition) for mechanical configuration, linear range, accuracy, and
temperature stability. All 3300 XL 8 mm proximity transducer systems provide
this level of performance and support complete interchangeability of probes,
extension cables, and Proximitor sensors, eliminating the need to match or
bench calibrate individual components.
Each 3300 XL 8 mm Transducer System component is backward-compatible and
interchangeable4 with other non-XL 3300 series 5 mm and 8 mm transducer
system components5. This compatibility includes the 3300 5 mm probe, for
applications in which an 8 mm probe is too large for the available mounting
6,7
space
Proximitor Sensor
The 3300 XL Proximitor Sensor incorporates numerous improvements over
previous designs. Its physical packaging allows you to use it in high-density DINrail installations. You can also mount the sensor in a traditional panel mount
configuration, where it shares an identical 4-hole mounting “footprint” with older
Proximitor Sensor designs. The mounting base for either option provides
electrical isolation and eliminates the need for separate isolator plates. The 3300
XL Proximitor Sensor is highly immune to radio frequency interference, allowing
you to install it in fiberglass housings without adverse effects from nearby radio
frequency signals. The 3300 XL Proximitor Sensor’s improved RFI/EMI immunity
satisfies European CE mark approvals without requiring special shielded conduit
or metallic housings, resulting in lower installation costs and complexity.
.
The 3300 XL’s SpringLoc terminal strips require no special installation tools and
facilitate faster, more robust field wiring connections by eliminating screw-type
clamping mechanisms that can loosen.

Proximity Probe and Extension Cable
The 3300 XL probe and extension cable also reflect
improvements over previous designs. A patented
TipLoc* molding method provides a more robust
bond between the probe tip and the probe body.
The probe’s cable incorporates a patented CableLoc*
design that provides 330 N (75 lbf) pull strength to
more securely attach the probe cable and probe tip.
You can also order 3300 XL 8 mm probes and
extension cables with an optional FluidLoc* cable
option. This option prevents oil and other liquids
from leaking out of the machine through the cable’s
interior.
Connectors
The 3300 XL probe, extension cable, and Proximitor
sensor have corrosion-resistant, gold-plated
ClickLoc* connectors. These connectors require only
finger-tight torque (the connectors will "click" when
tight), and the specially-engineered locking
mechanism prevents the connectors from loosening.
These connectors require no special tools for
installation or removal.
You can order the 3300 XL 8 mm probes and
extension cables with connector protectors already
installed. We can also supply connector protectors
separately for field installations (such as when an
application must run the cable through restrictive
conduit). We recommend connector protectors for
all installations to provide increased environmental
protection8.
Extended Temperature Range Applications
An extended temperature range (ETR) probe and ETR
extension cable are available for applications in
which either the probe lead or extension cable may
exceed the standard 177 C (350 F) temperature
specification. The ETR probe has an extended
temperature rating for up to 218 C (425 F). The ETR
extension cable rating is up to 260 C (500 F). Both
the ETR probe and cable are compatible with
standard temperature probes and cables, for
example, you can utilize an ETR probe with the
330130 extension cable. The ETR system uses the
standard 3300 XL Proximitor Sensor. Note that when
you use any ETR component as part of your system,
the ETR component limits the system accuracy to
the accuracy of the ETR system.
Description Notes:
1. One-metre systems do not use an extension cable.
2. Proximitor sensors are supplied by default from the
factory calibrated to AISI 4140 steel. Calibration to
other target materials is available upon request.
3. Consult Bently Nevada* Applications Note,
Considerations when using Eddy Current Proximity
Probes for Overspeed Protection Applications, when
considering this transducer system for tachometer or
overspeed measurements.
4. 3300 XL 8 mm components are both electrically and
physically interchangeable with non-XL 3300 5 mm
and 8 mm components. Although the packaging of
the 3300 XL Proximitor Sensor differs from its
predecessor, its design fits in the same 4-hole
mounting pattern when used with the 4-hole
mounting base, and will fit within the same mounting
space specifications (when minimum permissible
cable bend radius is observed).
5. Mixing XL and non-XL 3300-series 5 mm and 8 mm
system components limits system performance to the
specifications for the non-XL 3300 5 mm and 8 mm
Transducer System.
6. The 3300-series 5 mm probe (refer to Specifications
and Ordering Information p/n 141605-01) uses
smaller physical packaging, but does not reduce the
side view clearances or tip-to-tip spacing
requirements as compared to an 8 mm probe. It is
used when physical (not electrical) constraints
preclude the use of an 8 mm probe. When your
application requires narrow side view probes, use the
3300 NSv* Proximity Transducer System (refer to
Specifications and Ordering Information p/n 147385-
01).
7. 8 mm probes provide a thicker encapsulation of the
probe coil in the molded PPS plastic probe tip. This
results in a more rugged probe. The larger diameter
of the probe body also provides a stronger, more
robust case. We recommend that you use 8 mm
probes when possible to provide optimal robustness
against physical abuse.
8. Each 3300 XL extension cable includes silicone tape
that you can use instead of connector protectors. We
do not recommend silicone tape for applications that
will expose the probe-to-extension cable connection
to turbine oil.

our custom design department if
you require a test of the pressure

Note: 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, Inc. will
not be held responsible for any damages resulting from
