Bently Nevada 3300 XL NSv Specifications

3300 XL NSv Proximity Transducer System

Datasheet

Bently Nevada Machinery Condition Monitoring

Description

The 3300 XL NSv Proximity Transducer system is intended for
use with centrifugal air compressors, refrigeration
compressors, process gas compressors and other machines
with tight installation requirements. The 3300 XL NSv Proximity
Transducer System consists of:

l a 3300 NSv probe

l a 3300 NSv extension cable

l a 3300 XL NSv Proximitor Sensor

The primary uses for the 3300 XL NSv Transducer System are
for areas where counter bore, sideview or rearview restrictions
limit the use of standard Bently Nevada 3300 and 3300 XL 5
and 8 mm Transducer Systems. It is also ideal for small target
applications, such as measuring radial vibration on shafts
smaller than 51 mm (2 in) or axial position on flat targets
smaller than 15 mm (0.6 in). It is primarily used in the
following applications on fluid-filmed bearing machines
where a small shaft or reduced side-view is present:

l Radial vibration and radial position measurements

l Axial (thrust) position measurements

l Tachometer and zero speed measurements

l Phase reference (Keyphasor signals)

The 3300 XL NSv Transducer System design allows it to replace
both the 3300 RAM Transducer Systems and the 3000-series
or 7000-series 190 Transducer System. Upgrades from the
3300 RAM system to the 3300 XL NSv system may use the
existing probe, extension cable, and monitoring system with
3300 XL NSv Proximitor Sensor. Upgrades from the 3000-series
or 7000-series Transducer System must replace the probe,
extension cable and Proximitor Sensor with NSv components.

3300 XL NSv Proximity Transducer System
Datasheet 147385 Rev. K

The 3300 XL NSv Transducer System has an
Average Scale Factor of 7.87 V/mm (200
mV/mil), which is the most common output for
eddy current transducers. Its enhanced side­view and small target characteristics give it a
shorter linear range than the Bently Nevada
3300 XL-series 5 and 8 mm Transducer System.
With The 1.5 mm (60 mils) of linear range
exceeds the linear range of the 3000-series 190
Transducer System.

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 NSv Proximitor Sensor has similar
features to those found in the 3300 XL 8 mm
Proximitor Sensor. Its thin design allows the
user to mount it in either a high-density DIN-rail
installation or a more traditional panel mount
configuration. Improved RFI/EMI immunity
allows the 3300 XL NSv Proximitor Sensor to
achieve European CE mark approvals without
any special mounting considerations. This RFI
immunity also prevents nearby high frequency
radio signals from adversely affecting the
transducer system. SpringLoc terminal strips
on the Proximitor Sensor require no special
installation tools and facilitate faster, highly
robust field wiring connections.

The 3300 NSv probe comes in varying probe
case configurations, including armored and
unarmored ¼ -28, 3⁄8 -24, M8 X 1 and M10 X 1
probe threads. The reverse mount 3300 NSv
probe comes standard with either 3⁄8 -24 or
M10 X 1 threads. All components of the
transducer system have gold-plated brass
ClickLocconnectors. ClickLoc connectors lock
into place and prevent the connection from
loosening. The patented TipLocmolding
method provides a robust bond between the
probe tip and the probe body. Bently Nevada’s
patented CableLocdesign provides 220 N (50
lb) of pull strength and securely attaches the
probe cable to the probe tip. Connector
protectors are recommended for use on the
probe-to-extension cable connection, as well
as on the cable-to-Proximitor Sensor
connection. Connector protectors prevent
most liquids from entering into the ClickLoc
connectors and adversely affecting the
electrical signal

Notes:
(1) ProximitorSensors 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 NSv 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 NSv probe and extension cable are
mechanically and electrically compatible and
interchangeable with Bently Nevada’s previous
3300 RAM proximity probe and extension cable.
The NSv probe has increased chemical
resistance compared to the 3300 RAM probe,
which allows its use in many process
compressor applications. The side-view
characteristics of the 3300 NSv probe are also
superior to those of the 3000-series 190 probe
when gapping the 3300 NSv probe at the same
distance from the probe target.

Unless otherwise noted, the following
specifications are for a 3300 XL NSv Proximitor
Sensor, extension cable and probe between 0°C
and +45°C (+32°F to +113°F), with a -24 Vdc
power supply, a 10 kΩ load, a Bently Nevada
supplied AISI 4140 steel target that is 31 mm (1.2
in) diameter or larger, and a probe gap of 1.0
mm (40 mils). The system accuracy and
interchangeability specifications do not apply
when using a transducer system calibrated to
any target other than a Bently Nevada AISI 4140
steel target.

Recommended minimum: 13 mm
(0.5 in) diameter

Axial position measurements on
shaft diameters smaller than 13mm
(0.5 in) will generally result in a
change in scale factor. Reducing
the gap between the probe and
target will help limit the change in
scale factor. See Figure 12 for
additional information.

Minimum (standard X-Y probe
configuration): 30 mm (1.2 in)

Minimum (X-Y proximity probes
offset axially by 23 mm (0.9 in)): 20
mm (0.8 in)

Measurements on shaft diameters
smaller than 30 mm (1.2 in) usually
require close spacing of radial
vibration or axial position
transducers. This creates the
potential for their electromagnetic
emitted fields to interact with one

another (cross-talk), resulting in
erroneous readings. To prevent
cross-talk, maintain minimum
separation of m transducer tips of
at least 25 mm (1.0 in) for axial
position measurements or 23 mm
(0.9 in) for radial vibration
measurements. Probe Cross-talk

Radial vibration or radial position

generally result in greater than a

contains 10 pairs of connector
protectors.

Male Connector Protector. Placed on
the extension cable to connect to the
female connector protector on the
probe and provide environmental
protection of connectors.

Female Connector Protector. Placed
on the probe lead to connect to the
male connector protector on the
extension cable and provide
environmental protection of
connectors. Also placed on the
extension cable to slide over the
Proximitor Sensor connection and
protect it from the environment.

3300 NSv Connector Kit. Used on
3300 NSv probes and extension
cables. Contains one set of male and
