Description
The 3300 XL 25 mm Transducer System consists of a separate
25 mm probe, an extension cable, and a 3300 XL 25 mm
Proximitor Sensor. The 0.787 V/mm (20 mV/mil) output gives
this system a linear range of 12.7 mm (500 mils). Based on
this linear range, the 3300 XL 25 mm Transducer System issuitable for measuring differential expansion (DE) on midsize to large steam turbine generators caused by thedifference in growth rates between the turbine rotor and themachine stator (casing).

Measuring Differential Expansion (DE)The Differential Expansion measurement is made by two
proximity transducers observing a collar or ramp somedistance from the thrust bearing. Typical transducer
mounting arrangements are: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.

Two transducers with at least one transducer viewing a ramp
on a rotor and the second transducer viewing either aseparate ramp or a different location on the rotor tocompensate for radial movement. This arrangement adds
some error to the measurement, but can measure a longer
total DE distance than the complementary measurement.
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 (collar versus ramp). If sufficient collar height isavailable, two transducers observing the same side of a

cases come standard with a locknut withpredrilled safety wire holes.

collar is the preferred configuration. These twotransducers provide redundant measurements.

Proximitor Sensor
System Compatibility

The 3300 XL 25 mm Proximitor Sensor(1) has thesame advanced features as our previous 3300
XL Proximitor Sensors. Its thin design allows it tobe 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 also prevents the transducer systemfrom being 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.

The 3300 XL 25 mm probe comes in a large
variety of case configurations to physicallyreplace all standard 7200 25 mm, 7200 35 mm
and 25 mm DE Integral transducer systems(including side and rear exit probes). The
Proximitor Sensor also has an output that is
identical to that of the 7200 and 25 mm DE
Integral systems, allowing customers to
upgrade without requiring any changes in themonitor configuration. When upgrading fromprevious systems, every transducer systemcomponent (probe, extension cable, andProximitor Sensor) must be replaced with 3300
XL 25 mm components.

(1) Proximitor Sensors are supplied by

Proximity Probe and Extension
Cable

default from the factory calibrated to
AISI 4140 steel. Calibration to othertarget materials is available uponrequest.

The 3300 XL 25 mm probe is designed for
maximum survivability in the harshest steam
turbine DE environments. It can continuallyoperate and maintain its accuracy in hightemperatures up to 200 °C (392 °F), and canwithstand intermittent high temperatures up to
250 °C (482 °F). The 25 mm probe has both afront and rear seal which, combined with the
FluidLoc cable (standard on all 25 mm probes),
prevents moisture from entering the probe tip.
Special high-temperature ClickLoc connectors
are also standard on the probe and extension
cable. Each probe and cable are provided withconnector protectors and a disposableconnector protector installation tool to ensurethat the connectors remain free ofcontamination. The ClickLoc connector on theprobe lead has a removable collar thatfacilitates routing the cable through tightclearances.

Mounting Accessories
The correct operation of the transducer system
must be verified during installation, andperiodically after installation, by physicallymoving it to simulate the motion of the shaft
collar. This requires a mounting bracket thatallows the transducer system to slide relative tothe shaft rotor and collar.
An optional 3300 XL Sliding Bracket can beordered for the 25 mm Differential Expansion
Transducer for both single transducer andcomplementary input applications. This
mounting bracket makes it easy to accurately
verify the transducer system and gap theprobes by allowing you to slide the transducer
system throughout its linear range. The baseplate of the sliding bracket is installed on the
inner surface of the turbine case near thedifferential expansion collar. Probes are
installed in the applicable probe adapter,
which attaches to the sliding carriage. The
sliding carriage slides onto and is secured tothe base plate with bolts and safety wire. To

The 3300 XL 25 mm probe is available in many
probe case styles, including 1¼-12 or 1½-12
English threads, M30x2 or M39x1.5 metricthreads, or side or rear exit probes with a 1.06 or
1.50 in diameter smooth probe case.

verify and install the transducer, loosen thebolts securing the sliding carriage to the baseplate and move the sliding carriage andprobes. A Dial Indicator Verification Kit
accessory provides a reference by measuring
the movement of the sliding carriage. The 3300
XL Sliding Bracket helps ensure that thetransducer system remains aligned with andperpendicular to the rotor.
