Description:

The 3300 XL 25 mm Transducer System consists of a separate 5 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 is suitable for measuring differential expansion (DE) on midsize to large steam turbine generators caused by the difference in growth rates between the turbine rotor and the machine stator (casing).

Measuring Differential Expansion (DE)

The Differential Expansion measurement is made by two proximity transducers observing a collar or ramp some distance from the thrust bearing. Typical transducer mounting arrangements are:

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

Two transducers with at least one transducer viewing a ramp on a rotor and the second transducer viewing either a separate ramp or a different location on the rotor to compensate 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 of the available target, the expected amount of rotor axial movement and the type of DE target that exists in the machine (collar versus ramp). If sufficient collar height is available, two transducers observing the same side of a collar is the preferred configuration. These two transducers provide redundant measurements

08 Smooth 1.5 in dia. - Side Exit

B: Unthreaded Length Option

Standard unthreaded length is 0.0 mm or 0.0 in There is an additional charge for nonstandard unthreaded lengths.
Unthreaded length must be at least 26 mm or 1.0 in less than the case length. Unthreaded length option is 0.0 for smooth case probe types.

Metric Case Types Order in increments of 2 mm
Maximum Unthreaded Length 224 mm
Minimum Unthreaded Length 0 mm
Example 050 = 50 mm
English Case Types Order in increments of 0.1 in
Maximum Unthreaded Length 8.9 in
Minimum Unthreaded Length 0.0 in
Example 025 = 2.5 in

C: Overall Case Length Option

Standard case lengths are 26, 40, 60, 80, 100 and 250 mm for Metric cases and 1.0, 2.0, 3.0, 4.0, and 9.9 in for English cases. There is an additional charge for non-standard lengths.

Metric Case Types Order in increments of 2 mm

Maximum Unthreaded Length 250 mm
Minimum Unthreaded Length 26 mm
Example 050 = 50 mm

English and Smooth Case Types
Order in increments of 0.1 in
Maximum Unthreaded Length 9.9 in
Minimum Unthreaded Length 1.0 in (1.5 in for side exit case types)
Example 020 = 2.0 in

D: Total Length Option
10 1.0 metre (3.3 feet)
50 5.0 metres (16.4 feet)
90 9.0 metres (29.5 feet)
Five metre probes are designed for use with the five metre Proximitor Sensor ONLY.

E: Armor Option
00 No Armor
01 with SST Armor
When ordering SST Armor, the minimum probe length is 28 mm or 1.1 in

F: Agency Approval Option
00 No Approvals
05 Multiple Approvals

For a shorter delivery time, order commonly stocked multi-approvals probes.
Currently, stocked probes consist of the

Frequently Asked Questions:

1.What is Probe Pressure of 330851-02-000-070-50-00-05?

3300 XL probes are designed to seal differential pressure between the probe tip and case. The probe sealing material consists of a Viton O-ring and compression seal. Probes are not pressure tested prior to shipment. Contact our custom design department if you require a test of the pressure seal for your application.

2.What's Proximitor Sensor Temperature Range of 330851-02-000-070-50-00-05?
Operating Temperature -51°C to +100°C (-60°F to +212°F)

Storage Temperature -51°C to +105°C (-60°F to +221°F)
