Product Overview

The Bently Nevada 330103-00-05-20-02-05 stands as the industry benchmark for non-contact eddy current displacement sensing within the 3300 XL 8mm Transducer System. Engineered for the most demanding rotating machinery applications, this probe delivers high-resolution vibration and position data to Bently Nevada 3500 monitoring racks. It serves as the front-line sensor for Turbine Supervisory Instrumentation (TSI), identifying sub-micron shaft movements in steam turbines, gas compressors, and high-speed pumps. Its robust design ensures long-term stability and immunity to magnetic field interference, providing the critical data necessary for predictive maintenance and automated machinery protection circuits.

Model Configuration & Hardware Specifics

330103 Suffix Parameter Breakdown

The alphanumeric string 330103-00-05-20-02-05 dictates the specific mechanical footprint and electrical certification of the assembly:

Unthreaded Length (-00)

The 00 suffix denotes a 0.0-inch unthreaded length. This configuration provides a fully threaded probe body, allowing for maximum flexibility in mounting bracket adjustment and fine-tuning the target-to-tip clearance.

Overall Case Length (-05)

The 05 designation specifies a 0.5-inch overall case length. This ultra-compact housing is designed for shallow-depth installation points where space constraints prevent the use of standard-length probe bodies.

Total Length (-20)

The 20 suffix confirms a 2.0-meter (approximately 6.6 feet) total cable length. This integral cable connects directly to the 3300 XL extension cable, maintaining a consistent 5-meter or 9-meter system impedance.

Connector and Adapter Options (-02)

Equipped with a miniature coaxial connector and a factory-installed connector protector. The protector prevents fluid ingress and mechanical decoupling in high-vibration environments.

Agency Approval (-05)

The 05 option provides Multiple Approvals, encompassing ATEX, IECEx, and CSA certifications. This ensures global compliance for installation in Class I, Division 1 and Zone 0 hazardous areas.

Technical Performance Matrix

Field Implementation Strategy

Successful deployment requires precise mechanical gapping. Utilize a digital multimeter to measure the DC output at the Proximitor; a voltage of -10.00 VDC typically represents the center of the 80-mil linear range. Maintain a minimum side clearance of 1.5 times the probe tip diameter from any surrounding metal to avoid "side-loading" error. When routing the 2.0m cable, ensure the bend radius never drops below 25.4 mm (1.0 inch) to prevent internal coaxial fracturing. For installations involving oil-filled bearing housings, verify the integrity of the probe-to-case seal to prevent high-pressure leakage.

Industrial Resilience & Integration

The 3300 XL 8mm probe utilizes a specialized polyphenylene sulfide (PPS) tip, bonded to a stainless steel body. This material choice offers superior resistance to corrosive process fluids and high-temperature cycling. It integrates flawlessly with Honeywell Experion PKS or Yokogawa CENTUM VP systems via the Bently Nevada 3500/42M monitor. This synergy enables plant operators to move from reactive repairs to a data-driven "Condition Based Maintenance" (CBM) philosophy, significantly reducing unplanned downtime in Tier 1 industrial facilities.

Technical Inquiry & Support

Q1: Can I use this 2.0m probe with any 3300 XL Proximitor?

A1: You must match the total system length. This 2.0m probe requires a 3300 XL 5-meter or 9-meter system configuration. Ensure the extension cable and Proximitor are calibrated for the same total electrical length.

Q2: Is the 3/8-24 thread compatible with metric housings?

A2: No. This specific model uses imperial 3/8-24 UNF threads. For metric requirements, you would typically specify the 330105 (M10 x 1) series probes.

Q3: How do I identify if the connector protector is installed?

A3: The suffix -02 indicates the protector is present. It appears as a clear, reinforced sleeve over the miniature coaxial connector, providing environmental sealing when mated with the extension cable.
