Product Overview

The Bently Nevada 330104-02-12-10-01-00 3300 XL 8 mm Proximity Probe delivers highly stable shaft vibration and position measurement for critical rotating machinery. Engineers deploy this probe across steam turbines, compressors, pumps, centrifugal machines, and industrial motors where precise vibration trending directly impacts operational reliability and plant safety.

This 3300 XL probe continuously detects shaft displacement with exceptional linearity and signal integrity. The advanced eddy current sensing architecture minimizes signal distortion caused by electrical noise, temperature fluctuation, and harsh industrial environments. The probe integrates seamlessly with Bently Nevada 3500 monitoring systems, TSI frameworks, and distributed control systems including Honeywell Experion PKS.

Its rugged construction supports long-term installation in demanding oil & gas, petrochemical, power generation, and heavy manufacturing facilities. The compact probe body allows flexible installation inside confined bearing housings while maintaining accurate gap voltage performance under continuous operation.

Probe Configuration Breakdown

Model Logic Analysis

Core Sensing Technology

The 3300 XL platform uses non-contact eddy current measurement technology to monitor shaft movement with high repeatability. The probe system generates a high-frequency electromagnetic field and instantly converts shaft displacement into a proportional voltage signal.

The system maintains outstanding linear response over the calibrated measurement range while resisting oil contamination, humidity, and electromagnetic interference commonly found in turbine compartments and compressor skids.

Mechanical & Electrical Specifications

Field Installation Recommendations

Maintain proper probe target alignment during installation to ensure stable waveform output and accurate vibration trending. Engineers should verify shaft surface cleanliness before setting final probe gap voltage.

Avoid excessive cable bending near the probe connector. Maintain a minimum bending radius of at least ten times the cable diameter to preserve shielding effectiveness and signal stability.

Install the probe cable separately from high-voltage power wiring. Proper grounding significantly reduces electromagnetic interference inside turbine control cabinets and compressor monitoring panels.

For hazardous-area installations, use certified conduit sealing methods and confirm compatibility with local explosion-proof regulations before energizing the monitoring system.

Operational Reliability & System Integration

The 3300 XL probe platform performs reliably under high-temperature, oil-contaminated, and high-vibration operating conditions commonly found in refinery and power generation environments.

The probe integrates directly into Bently Nevada 3500 machinery protection systems and supports continuous condition monitoring strategies across TSI infrastructures. Maintenance teams gain accurate real-time shaft position and vibration diagnostics without interrupting equipment operation.

Its robust shielding architecture suppresses external noise interference and maintains clean waveform transmission over extended cable routing distances. This capability becomes critical in large compressor trains and turbine skids where electrical interference frequently compromises low-quality sensing systems.

The compact sensor structure also simplifies retrofit projects inside legacy monitoring installations with limited mounting space.
