Bently Nevada 330103-00-03-50-02-05 3300 XL 8 mm Proximity Probe

Description

330103-00-03-50-02-05: 3300 XL 8 mm proximity probe, M10 x 1 metric thread, unarmored, Option 00 fully threaded (0 mm unthreaded length), Option 03 case length of 30 mm, Option 50 total length of 5.0 m, Option 02 standard coaxial cable, and Option 05 CSA/ATEX/IECEx approvals.

This metric-threaded eddy-current transducer is designed to measure static displacement and shaft vibration on rotating machinery. By generating a high-frequency electromagnetic field, the sensor tracks the gap change between the 8 mm tip and any conductive metal target, sending a proportional analog voltage signal back to the monitoring system. The 5.0-meter total system length allows direct routing from the machine housing to the transmitter, optimizing signal integrity by removing intermediate connector junctions.

The unarmored, FEP-insulated coaxial cable is equipped with a miniature ClickLoc connector, providing reliable performance in environments exposed to moisture, oils, and chemical vapors. This specific configuration utilizes a fully threaded body to maximize adjustment depth inside tight installation spaces. Certifications provided by Option 05 ensure compliant installation in global hazardous and intrinsically safe machinery loops.

Features

• M10 x 1 Metric Thread: Standard mounting configuration for direct installation on metric-tapped equipment machinery housings.
• Fully Threaded Body (Option 00): Zero unthreaded length enables full-depth thread engagement and flexible gap positioning.
• 30 mm Case Length (Option 03): Low-profile housing is ideal for compact bearing structures and limited clearances.
• 5.0 m Cable Length (Option 50): Direct connection to a 5-meter Proximitor sensor simplifies loops and eliminates separate extension cables.
• Standard FEP-Insulated Cable (Option 02): Highly resistant to corrosive industrial chemicals, solvents, and oil splash.
• Gold-Plated ClickLoc Connector: Reliable coaxial connection resistant to structural vibration and contact corrosion.
• Global Approvals (Option 05): Hazardous area approvals including CSA, ATEX, and IECEx for intrinsically safe machinery protection.

Applications

This proximity probe is used in high-demand industrial sectors such as power generation, petrochemicals, oil and gas, and wastewater treatment. Typical applications include:

• Shaft radial vibration monitoring in fluid-film bearings.
• Thrust position and axial shaft displacement tracking on steam and gas turbines.
• Rotor dynamic analysis and eccentricity measurements.
• Keyphasor reference measurements for phase-angle alignment and machine speed calculation.

Installation Guidelines

• Case Torque Limit: Do not exceed the maximum rated installation torque of 22.6 N-m (200 in-lbf) for M10 x 1 threaded cases. Recommended installation torque is 7.5 N-m (66 in-lbf).
• Cable Bend Radius: Ensure standard triaxial FEP-insulated coaxial cables are routed with a bend radius of no less than 25.4 mm (1.0 in) to protect electrical shielding.
• Target Clearance: Maintain a minimum of 22 mm diameter clear zone around the probe tip to prevent adjacent mechanical structures from interfering with calibration or causing cross-talk.
• Cable Protection: Avoid parallel routing adjacent to high-voltage power lines to maintain high signal-to-noise ratios.

Compliance and Certifications

• ATEX/IECEx: Ex ia IIC T5...T1 Ga; Ex ia IIIC T90C/T105C Dc for intrinsically safe applications.
• CSA/NRTL/C: Class I, Division 1, Groups A, B, C, D; Class II, Groups E, F, G; Class III.
• CE Mark: Compliant with Electromagnetic Compatibility (EMC) Directive 2014/30/EU and RoHS Directive 2011/65/EU.
• Functional Safety: Certified SIL 2 capable (HFT=0) under standard machinery safety parameters.
