Quick Detail

Description

The 330704-00-030-50-02-00 3300 XL 11 mm Proximity Probe is a high-performance eddy current transducer designed for precise non-contacting vibration and position measurements in fluid-film bearing machines, steam turbines, reciprocating compressors, and other industrial equipment. Featuring a large 11 mm probe tip and a linear range exceeding standard 8 mm XL probes, this system provides 3.94 V/mm (100 mV/mil) output, ensuring highly accurate axial (thrust) position, rotor expansion, and differential movement measurements.

The probe comes with a 5-meter standard extension cable, M14 x 1.5 probe thread, and ClickLoc connectors with 99.9% braided copper shielding, offering IP67-rated dust and water protection. Its TipLoc molding method ensures a robust bond between probe tip and body, while the CableLoc design provides 330 N (75 lbf) pull strength, securing the probe cable. Optional FluidLoc cable and connector protectors prevent liquid ingress and maintain signal integrity in harsh environments. The probe supports forward and reverse mount configurations, armored or unarmored cases, and is fully compatible with modern 3300 XL Transducer Systems for seamless upgrades from 7200-series transducers.

This 3300 XL 11 mm probe system is ideal for applications requiring extended linear range, high environmental resistance, and reliable operation in high-temperature or high-humidity conditions, making it a preferred choice for industrial vibration monitoring, position sensing, and turbine differential expansion measurements.

Applications

Turbine and Compressor Vibration Monitoring
The 330704-00-030-50-02-00 measures shaft radial vibration and Keyphasor speed signals in turbines and compressors. Its M14 x 1.5 mounting thread and 5.0 m cable length allow integration across compressor skids and turbine bearing housings where extended routing and EMI suppression are required.

Pump and Gearbox Condition Monitoring
With IP67 environmental protection and 99.9% braided copper shielding, the 330704-00-030-50-02-00 supports long-term operation in pump trains and gearbox assemblies exposed to lubricant mist, dust, and high ambient temperatures, enabling system reliability and predictive maintenance analytics.

Automation and Machine Protection Systems
The 330704-00-030-50-02-00 interfaces with industrial automation platforms and vibration protection systems to measure shaft displacement, axial position, and event timing signals. Its ClickLoc miniature connector improves field wiring efficiency and prevents accidental disconnects.

Refinery, Petrochemical, and Heavy-Industry Installations
The 330704-00-030-50-02-00 supports refinery and process-plant environments where IP67 ingress protection and EMI resistance are essential for maintaining sensor accuracy during continuous-duty operation and thermal fluctuations.

Specifications

Competitive Advantage

Extended Linear Range
11 mm tip ensures longer linear measurement range compared to standard 8 mm XL probes, ideal for large displacement or axial movement monitoring.

High Environmental Resistance
IP67-rated housing with optional FluidLoc cables and connector protectors provides superior protection against dust, moisture, and industrial contaminants.

Robust Mechanical Design
TipLoc and CableLoc designs offer 330 N (75 lbf) pull strength, ensuring secure connections and reliable operation in high-vibration environments.

High Signal Accuracy
3.94 V/mm (100 mV/mil) output maintains consistent precision across the linear range, with minimal sensitivity to supply voltage variation (<2 mV/V).

Flexible Installation and Compatibility
Supports multiple thread types (M14 x 1.5, ½-20, M16 x 1.5) and mounting orientations, fully compatible with 3300 XL systems and upgradable from 7200-series transducers.
