Description
Transducer System
The 3300 5 mm Proximity Transducer System consists of:llla 3300 5 mm probe 1, 2
a 3300 XL extension cable (ref 141194-01)
a 3300 XL Proximitor Sensor 3, 4, 5 (ref 141194-01)

When combined with a 3300 XL Proximitor Sensor and XL
extension cable, the system provides an output voltage thatis directly proportional to the distance between the probe tip
and the observed conductive surface. The system canmeasure both static (position) and dynamic (vibration) data.
Its primary use is in vibration and position measurement
applications on fluid-film bearing machines, as well as
Keyphasor measurement and speed measurement
applications6.
The system provides an accurate, stable signal output over awide temperature range. All 3300 XL Proximity Transducer
Systems achieve this level of performance with complete
interchangeability of probe, extension cable, and Proximitor
sensor, eliminating the need for individual component
matching or bench calibration.

Proximity Probe
The 3300 5 mm probe improves upon previous designs. A
patented TipLoc molding method provides a more robustbond between the probe tip and the probe body. The 3300 5
mm system is orderable with Fluidloc cable options forpreventing oil and other liquids from leaking out of themachine through the cable’s interior.

optimal robustness against physicalabuse.

3. A 3300 XL Proximitor Sensor is available
and provides many improvements overthe non-XL version. The XL sensor iselectrically and mechanicallyinterchangeable with the non-XL
version. Although the packaging of the3300 XL Proximitor Sensor differs from its
predecessor, its design allows for theuse of a 4-hole mounting base to fit it in
the same 4-hole mounting pattern andto fit within the same mounting space
specifications (when the application
observes the minimum permissible
cable bend radius). Consult
Specifications and Ordering Information(p/n 141194-01) or our sales and service
professional for more information.

The 3300 5 mm probe and 3300 XL extension
cable have corrosion-resistant, gold-plated
brass ClickLoc connectors. These connectors
require only finger-tight torque (connectors will"click"), and the specially engineered locking
mechanism prevents the connectors fromloosening. The connectors require no special
tools for installation or removal.
3300 5 mm Probes and XL Extension Cables canbe ordered with connector protectors alreadyinstalled, or we can supply the connector
protectors separately for installation in the field(such as when the cable must be run throughrestrictive conduit). We recommend connector
protectors for all installations to provide
increased environmental protection7.
Notes:
1. A 5 mm probe uses smaller physicalpackaging and provides the same
linear range as a 3300 XL 8 mm probe(ref 141194-01). The 5 mm probe does
not, however, reduce the sideview
clearances or tip-to-tip spacing
requirements as compared to an XL 8
mm probe. Use the 5 mm probe when
physical (not electrical) constraints
preclude the use of an 8 mm probe,
such as mounting between thrustbearing pads or other constrained
spaces. When your application requires
narrow sideview probes, use the 3300 XL
NSv probe and extension cable with the3300 XL NSv Proximitor Sensor (refer toSpecifications and Ordering Information
p/n 147385-01).

4. Use of XL components with 3300 5 mm
Probes will limit system performance tothe specifications for the non-XL 3300
system.
5. The factory supplies Proximitor Sensors
that are calibrated by default to AISI
4140 steel. Calibration to other target
materials is available upon request.
6. When using this transducer system fortachometer or over-speed
measurements, consult Bently.com forthe application note regarding the useof eddy current proximity probes forover-speed protection.
7. We provide silicone tape with each 3300
XL extension cable. Use this tape insteadof connector protectors. We do notrecommend silicone tape inapplications which will expose theprobe-to-extension cable connection toturbine oil.

2. XL 8 mm probes provide a thicker
encapsulation of the probe coil in themolded PPS plastic probe tip to produce
a more rugged probe. The larger
diameter of the probe body also
provides a stronger, more robustcase. We recommend the use of XL 8
mm probes when possible to provide

Probe Pressure
3300 5mm probes are designed to sealdifferential pressure between the probe tip
and case. The probe sealing material consistsof a fluorocarbon O-ring. We do not pressure
test probes prior to shipment. Contact ourcustom design department if a test of thepressure seal for your application is required.
It is the responsibility of thecustomer or user to ensure that all
liquids and gases are contained
and safely controlled should aproximity probe leak. In addition,
solutions with high or low pH values
may erode the tip assembly of theprobe causing media to leak into
surrounding areas. Bently Nevada
does not be held responsible for any
damages resulting from leaking
3300 5 mm proximity probes. In
addition, Bently Nevada does not
