BENTLY NEVADA 330103-00-10-05-02-05 – 3300 XL Proximity Probe for Turbomachinery Shaft Vibration and Position

The Bently Nevada 330103-00-10-05-02-05 is part of the 3300 XL proximity measurement system that plants rely on for continuous protection of critical rotating equipment. It’s the probe element in an eddy-current chain (probe + extension cable + Proximitor sensor) used to measure shaft displacement, rotor position, and vibration on turbines, compressors, pumps, and generators. One thing I appreciate is how predictable the 3300 XL system behaves in the field—when paired with the matching Proximitor, you typically get the well-known 7.87 mV/µm (200 mV/mil) sensitivity and stable bias voltage checks, which makes commissioning faster and less error-prone.

• Express options: FedEx, UPS, DHL

Key Features

• 3300 XL system compatibility: Designed to operate with 3300 XL Proximitor sensors for accurate displacement and vibration readings.
• Non-contact eddy-current sensing: Measures shaft movement without mechanical contact—ideal for high-speed machinery.
• Stable, industry-standard sensitivity: With the matching Proximitor, the system typically provides 7.87 mV/µm (200 mV/mil).
• Robust construction: Stainless-steel probe body and shielded coax help in oily, high-vibration environments.
• Option-coded configuration: The suffix “-00-10-05-02-05” defines probe build options (length, mounting, and connector style) for drop-in replacement.
• API 670-friendly deployments: Commonly used in API 670-compliant machinery protection architectures.
• Wide system lengths: Typical total system lengths up to 9 m (probe + extension cable), depending on the selected option codes.

Technical Specifications

Application Fields

From my experience, you’ll most often see 330103 probes on:

• Steam and gas turbines (radial vibration, shaft position)
• Centrifugal compressors and expanders
• Critical process pumps and high-speed motors
• Gearboxes and generators in continuous-process plants

“We swapped like-for-like 330103 probes during a turnaround; bias voltage and linearity were right on spec, so loop checks took minutes instead of hours.” — Maintenance Supervisor, combined-cycle plant

Advantages & Value

• Reliability under harsh conditions: The 3300 XL chain is built for oil-film bearings and high vibration. It just holds calibration well.
• Compatibility that reduces risk: Drop-in with existing 3300 XL Proximitors and 3500 racks; no re-engineering of monitoring logic in most cases.
• Predictable commissioning: Standard bias and sensitivity make acceptance testing straightforward for API 670-style checks.
• Spares strategy friendly: Option-coded part numbers align with your installed base, simplifying maintenance inventory.
• Cost of downtime mitigation: Faster changeouts and proven behavior help shorten outage durations.

Installation & Maintenance

• Mounting: Install the probe through a rigid bracket or machine casing; secure with locknut. Maintain a clean target surface on the shaft.
• Gap setting: With the system powered, adjust for the specified bias voltage window (typical for 3300 XL) rather than “feel” alone.
• Cable routing: Use gentle bends; avoid tight radii and high-EMI paths. Keep the coax shield continuous to the Proximitor.
• Cabinet environment: Mount the Proximitor in a ventilated cabinet; follow grounding and segregation best practices for analog signals.
• Safety: Lock-out/tag-out rotating equipment; verify no rubbing or contact under thermal growth.
• Routine care: Inspect probe tips during outages, wipe away oil varnish, verify bias voltage quarterly, and document linearity checks during turnarounds.

Quality & Certifications

• Compliance: Typically CE and RoHS when used as part of the 3300 XL system; designed for use in API 670-style protection systems.
• Warranty (from us): 365 days coverage.
