Bently Nevada Machinery Condition Monitoring

147385 Rev. P

Description
The 3300 XL NSv Proximity Transducer system is intended foruse with centrifugal air compressors, refrigeration
compressors, process gas compressors, and other machineswith tight installation requirements. The 3300 XL NSv Proximity
Transducer System consists of:la 3300 NSv probela 3300 NSv extension cablel

a 3300 XL NSv Proximitor Sensor(1)The primary uses for the 3300 XL NSv Transducer System arefor 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 forsmall target applications, such as measuring radial vibration
on shafts smaller than 51 mm (2 in) or axial position on flattargets smaller than 15 mm (0.6 in). It is primarily used in thefollowing applications on fluid-filmed bearing machines
where a small shaft or reduced side-view is present:lRadial vibration and radial position measurementsl

Axial (thrust) position measurementslTachometer and zero speed measurementslPhase reference (Keyphasor signals)

The 3300 XL NSv Transducer System design allows it toreplace both the 3300 RAM Transducer Systems and the3000-series or 7000-series 190 Transducer System. Upgradesfrom the 3300 RAM system to the 3300 XL NSv system may
use the existing probe, extension cable, and monitoring3300 XL NSv Proximity Transducer System

Sensor. Upgrades from the 3000-series or
7000-series Transducer System must replace
the probe, extension cable, and Proximitor
Sensor with NSv components.

compressor applications. The side-view
characteristics of the 3300 NSv probe are alsosuperior to those of the 3000-series 190 probe
when gapping the 3300 NSv probe at the same
distance from the probe target.

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

The 3300 NSv probe comes in varying probe
case configurations, including armored andunarmored 1/4-28, 3⁄8-24, M8X1 and M10X1
probe threads. The reverse mount 3300 NSv
probe comes standard with either 3⁄8-24 or
M10X1 threads. All components of thetransducer system have gold-plated brass
ClickLoc connectors. ClickLoc connectors lock
into place and prevent the connection fromloosening. The patented TipLoc molding
method provides a robust bond between theprobe tip and the probe body. Bently Nevada’s
patented CableLoc design provides 220 N (50lb) of pull strength and securely attaches theprobe cable to the probe tip. Connector
protectors are recommended for use on theprobe-to-extension cable connection, as wellas on the cable-to-Proximitor Sensor
connection. Connector protectors prevent mostliquids from entering into the ClickLoc
connectors and adversely affecting theelectrical signal(2).

Although the terminals andconnector on the Proximitor Sensor
have protection against electrostatic
discharge, take reasonableprecautions to avoid electrostatic
discharge during handling.

Proximitor Sensor
The 3300 XL NSv Proximitor Sensor has similarfeatures 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 mountconfiguration. Improved RFI/EMI immunity
allows the 3300 XL NSv Proximitor Sensor toachieve European CE mark approvals without
any special mounting considerations. This RFI
immunity also prevents nearby high frequency
radio signals from adversely affecting thetransducer system. SpringLoc terminal strips on
the Proximitor Sensor require no special
installation tools and facilitate faster, highlyrobust field wiring connections.

Notes:(1) Proximitor Sensors are supplied by default
from the factory calibrated to AISI 4140 steel.
Calibration to other target materials isavailable upon request.
(2) Silicone tape is also provided with each3300 NSv extension cable and can be usedinstead of connector protectors. Silicone tape is
not recommended in applications where theprobe-to-extension cable connection will be
exposed to turbine oil.

Proximity Probe and Extension
Cable
The 3300 NSv probe and extension cable aremechanically and electrically compatible andinterchangeable 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

Figure 12 for additional
information.

Shaft Diameter

4/34

Measurements on shaft
diameters smaller than 30
mm (1.2 in) usually require
close spacing of radialvibration or axial positiontransducers. This creates
the potential for theirelectromagnetic emitted
fields to interact with one
another (cross-talk),
resulting in erroneous
readings. To preventcross-talk, maintainminimum separation oftransducer tips of at least
25 mm (1.0 in) for axial
position measurements or
23 mm (0.9 in) for radialvibration measurements.
See Figure 14: Probe Crosstalk with Probes Mounted in

measurements on shaft
