Key Differentiators for the 50 mm Model
Features:
- Consists of 50 mm Probe, Extension Cable, and 3300 XL 50 mm Proximitor Sensor
- Maximum Linear Range of 27.9 mm (1100 mils)
- Measures the Differential Expansion (DE) or Rotor Expansion (RX) of Steam Turbine Generators
The Bently Nevada 3300 XL 50mm Proximity 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 a maximum 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 for measuring the differential expansion (DE) or rotor expansion (RX) of large steam turbine generators that results from the difference in growth rates between the turbine rotor and the machine stator (casing).
The 330878-51-05 Bently Nevada 3300 XL 50 mm Proximity Sensor may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The Differential Expansion measurement is made by usingtwo proximity transducers that observe a collar or rampsome distance from the thrust bearing. Typical transducermounting arrangements that require the 3300 XL 50 mmTransducer’s long linear range include:Two transducers observing the same side of a collar.Two complementary input transducers observingopposite 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 axialmovement, and the type of DE target that exists in themachine. If the collar height is sufficient and the requiredtotal measurement range is less than 27.9 mm 1.1 inches, thepreferred configuration for redundant measurements is touse two transducers observing the same side of a collar.When 28 mm to 56 mm (1.1 to 2.2 inches) of total range arerequired, install the transducers in a complementary fashion on opposite sides of the differential expansioncollar or other target material.
- Power Generation Plants:Monitors steam turbine rotor-casing differential expansion during temp changes
- Oil & Gas Refineries:Up to 200°C: monitors compressors/pumps to prevent downtime
- Petrochemical Complexes:3500 rack integration for motors/generators stability
- Pulp & Paper Mills:Optimizes maintenance & reduces costs for heavy rotating equipment
- Mining & Metal Mills:High-precision vibration/position for large shafts in rough conditions
This content has been produced using multiple sources.Amikon takes no responsibility for the accuracy of this information. Always consult the original equipment manufacturer for the most up to date instructions and information.
Longest Range: It offers the longest linear measurement of any Bently Nevada eddy current sensor.
Target Size Requirement: Because of its large 50 mm tip, it requires a much larger target area (102 mm diameter) to maintain its calibrated accuracy.
Legacy Replacement: This model is the modern, more robust replacement for older 7200 series 50 mm and 130713 DE systems.
Specialty vs. Versatility: Unlike the 8 mm system, which is highly interchangeable across many machines, the 50 mm is a specialty tool used strictly where extreme displacement (over 1 inch) must be tracked.
