Description
The 3300 XL 50 mm Transducer System consists of a separate
50 mm probe, an extension cable, and a 3300 XL 50 mm
Proximitor Sensor. The large diameter coil gives this system amaximum linear range of 27.9 mm (1100 mils), the longest
linear range of our eddy current transducer line. This linear
range makes the 3300 XL 50 mm Transducer System ideal formeasuring the differential expansion (DE) or rotor expansion(RX) of large steam turbine generators that results from thedifference in growth rates between the turbine rotor and themachine stator (casing).

Measuring Differential Expansion
The Differential Expansion measurement is made by using
two proximity transducers that observe a collar or ramp
some distance from the thrust bearing. Typical transducer
mounting arrangements that require the 3300 XL 50 mm
Transducer’s long linear range include:ll

Two transducers observing the same side of a collar.
Two complementary input transducers observing
opposite sides of a collar, effectively doubling themeasurable DE range.

The criteria for selecting a mounting method are the size ofthe available target, the expected amount of rotor axial
movement, and the type of DE target that exists in themachine. If the collar height is sufficient and the required
total measurement range is less than 27.9 mm 1.1 inches, thepreferred configuration for redundant measurements is to
use two transducers observing the same side of a collar.
When 28 mm to 56 mm (1.1 to 2.2 inches) of total range are
required, install the transducers in a complementary fashion

and side exit probes the overall case diameteris 1.99 inches.

on opposite sides of the differential expansion
collar or other target material.

System Compatibility

Proximitor Sensor

The 3300 XL 50 mm probe comes in three case& thread configurations to physically replace
all standard 7200 50 mm systems (includingside and rear exit probes). The standard 7200
style mounting brackets are still available asaccessories. In addition, a new bracket toadapt the probe to the 50 mm DE Integral
transducer sliding mount base is also available.
The Proximitor Sensor has a 0.394 V/mm (10mV/mil) output that is identical to that of the7200 and 50 mm DE Integral systems, whichallows customers to upgrade without requiring
any changes in the monitor configuration.
When upgrading from previous systems, everytransducer system component (probe,
extension cable, and Proximitor Sensor) must
be replaced with 3300 XL 50 mm components.

The 3300 XL 50 mm Proximitor Sensor has thesame advanced features as all 3300 XL
Proximitor Sensors. Its thin design allows it to be
mounted in either a high-density DIN-rail
installation or a more traditional panel mountconfiguration. Improved RFI/EMI immunity
allows the 3300 XL Proximitor Sensor to achieve
European CE mark approvals without any
special mounting considerations. This RFI
immunity prevents the transducer system frombeing adversely affected by nearby highfrequency radio signals. SpringLoc terminal
strips on the Proximitor Sensor require no
special installation tools and facilitate faster,highly robust field wiring connections.
Proximitor Sensors are supplied bydefault from the factory calibrated to
AISI 4140 steel. Calibration to othertarget materials is available uponrequest.

Proximity Probe and Extension Cable
The 3300 XL 50 mm probe is designed tosurvive the harshest steam turbine DE
environments. It can continually operate andmaintain its accuracy in high temperatures up
to 200°C (392°F), and can withstandintermittent high temperatures up to 250°C(482°F). The 50 mm probe has both a front andrear seal which, combined with the High
Temperature FluidLoc cable (standard on all 50
mm probes), prevent moisture from entering
the probe tip. Special high-temperature
ClickLoc connectors are also standard on theprobe and extension cable. Each probe andcable comes with connector protectors and adisposable connector protector installation tool
to ensure that the connectors remain free ofcontamination. The ClickLoc connector on theprobe lead features a removable collar thatfacilitates routing the cable through tightclearances.

Mounting Accessories
The correct operation of the transducer system
must be initially verified during installation andperiodically thereafter. This is done byphysically moving the transducer to simulate
the motion of the shaft collar. This requires amounting bracket that allows the transducer
system to slide relative to the shaft rotor andcollar.
An optional Sliding Bracket can be ordered forthe 50 mm Transducer for both single
transducer and complementary input
applications. This mounting bracket allows you
to verify the transducer system and gap theprobes by sliding the transducer systemthrough its linear range. The base plate of thesliding bracket is installed on the inner surfaceof the turbine case near the differential
expansion collar. Probes are installed in theprobe clamp that attaches to the sliding

The 3300 XL 50 mm probe is available instraight exit case styles with ½-20 English
threads or M14x1.5 metric threads, including alocknut with predrilled safety wire holes. The
side exit probe has two ¼-20 mounting holes in

carriage. The sliding carriage slides onto and issecured to the base plate with bolts and safety
wire. To verify and install the transducer, loosen
the bolts securing the sliding carriage to thebase plate and move the sliding carriage andprobes. A verification kit with spindle
micrometer can be temporarily secured to thebase plate to provide a reference for axial
verification measurements. The spindle
micrometer measures the movement of thetransducer system relative to the collar during
these verification tests.

for all internal threads. Applications
with thread engagement lengths
exceeding the values in the table

installation. Contact your Bently
Nevada representative if you require
probe thread engagement lengths
exceeding the values above. Bently

It is the responsibility of the customer
or user to ensure that all liquids andgases are contained and safely
controlled should leakage occur froma proximity probe. In addition,
solutions with high or low pH values
may erode the tip assembly of theprobe causing media leakage into
