Bently Nevada 3300A02-50-00 3300 XL 50 mm Transducer System

The Bently Nevada 3300A02-50-00, also cataloged as the 3300 XL 50 mm Transducer System, operates as a dedicated hardware component for eddy-current displacement measurement within large machine rotor expansion monitoring applications. The system provides axial position signals for differential expansion and rotor expansion evaluation.

Hardware Specifications

Eddy-Current Probe Scaling and Rotor Dynamics Monitoring

The 3300 XL 50 mm Transducer System uses a large diameter eddy-current probe coil to provide extended linear displacement measurement capability. The system supports rotor dynamics monitoring by detecting axial movement between turbine rotor and stator structures caused by differential growth.

The eddy-current measurement chain supports gap voltage validation with -10 VDC target conditions used for probe gap setup verification. Proper probe scaling and mechanical alignment are required to maintain displacement measurement performance across the available linear range.

Differential expansion measurement is performed using two proximity transducers positioned relative to a collar or ramp near the thrust bearing. The configuration may use two probes observing the same side of the target or complementary probes installed on opposite sides to increase the measurable differential expansion range.

Field Installation Guidelines

Install the 50 mm probe assembly with correct mechanical positioning relative to the monitored rotor expansion target. Verify target surface condition, probe alignment, and mounting rigidity before commissioning.

Route extension cables away from high-current conductors and electromagnetic interference sources. Maintain appropriate shielding and grounding practices for low-level eddy-current measurement signals.

For differential expansion installations, select probe arrangement according to the available collar geometry and required axial measurement range. Verify probe gap conditions and signal response before enabling machinery protection functions.
