Product Overview

The Bently Nevada 330101-00-36-05-02-05 is a high-performance 8mm proximity probe belonging to the industry-standard 3300 XL series. Engineered for non-contacting displacement and vibration measurements, this probe serves as the critical "eyes" for your machinery protection system. It excels in monitoring high-speed rotating assets such as steam turbines, centrifugal compressors, and large motors. By delivering a highly linear voltage output proportional to the gap between the probe tip and the target shaft, it provides essential data for early fault detection, including rotor imbalance and bearing wear. The 3300 XL system offers superior temperature stability and interchangeability, making it the primary choice for global Emergency Shutdown (ESD) and Turbine Supervisory Instrumentation (TSI) applications.

Component Configuration & Suffix Logic

The 330101-00-36-05-02-05 model code specifies a precise mechanical and electrical profile tailored for rugged industrial bearing housings.

Unthreaded Length (-00)

Specifies a 0.0-inch unthreaded length. This indicates the probe body is fully threaded, providing maximum flexibility for axial adjustment during the gapping process.

Overall Case Length (-36)

Defines a 3.6-inch total case length. This dimension ensures the probe can penetrate standard bearing pedestals while maintaining high mechanical resonance frequency.

Total Length (-05)

Represents a 0.5-meter (1.6 feet) total cable length. This short-lead design is optimized for installations where the Proximitor is located in a nearby junction box, minimizing electrical noise pickup.

Connector Option (-02)

Equipped with a miniature coaxial ClickLoc connector. This gold-plated interface provides a moisture-resistant, vibration-proof connection to the extension cable.

Agency Approval (-05)

Indicates "Multiple Approvals," including CSA, ATEX, and IECEx certifications. This allows for safe deployment in Zone 0, Zone 1, and Division 1 hazardous locations worldwide.

Performance Characteristics

Precise Field Installation Guide

Engineers must prioritize "Gap Voltage" calibration during commissioning. Use a high-impedance digital multimeter to set the initial gap; a reading of -10.00 Vdc typically represents the center of the linear range for 3300 XL 8mm probes. Ensure the target shaft area is free of mechanical runout and magnetic "soft spots" (residual magnetism) to prevent signal "glitch." Maintain a minimum cable bend radius of 25.4 mm (1 inch). For hazardous area installations, ensure the ClickLoc connector is properly insulated with the supplied silicone tape or heat-shrink tubing to prevent ground loops and maintain the Ex-rating integrity.

Operational Advantages & System Synergy

The 330101-00-36-05-02-05 probe offers a 30% improvement in temperature stability over previous generations, significantly reducing "false trips" caused by thermal expansion in the bearing housing. Its Polyphenylene Sulfide (PPS) tip resists corrosive oil mists and synthetic lubricants, ensuring a service life often exceeding 10 years. This probe integrates seamlessly with the Bently Nevada 3500/42M Proximitor/Seismic Monitor and provides reliable data for DCS platforms like Honeywell Experion PKS through high-fidelity buffering.

Technical Consultation FAQ

Q1: Can I use this 0.5m probe with a 9.0m Proximitor?

A1: Yes, provided you use an 8.5m extension cable. The total electrical length of the probe plus the extension cable must always match the calibrated length of the Proximitor (either 5.0m or 9.0m).

Q2: What happens if the probe tip is scratched?

A2: Minor scratches on the Ryton/PPS tip do not usually affect the eddy current field. However, if the internal coil is exposed or deformed, the scale factor will shift, and the probe must be replaced to ensure system accuracy.

Q3: Does the -05 approval cover both ATEX and North American standards?

A3: Correct. The -05 suffix is a "Multi-Approval" option, certifying the probe for global use under CSA (Canada/US) and ATEX/IECEx (Europe/International) hazardous area regulations.
