Product Overview

The Bently Nevada 330103-00-13-10-12-05 3300 XL 8 mm Proximity Probe delivers vital non-contact displacement metrics for industrial predictive maintenance strategies. This heavy-duty eddy current sensor continuously tracks radial vibration, shaft thermal expansion, and axial alignment parameters on critical rotating machinery.

Control engineers integrate this exact probe configuration within Turbine Supervisory Instrumentation (TSI) layouts to safeguard high-capital assets like steam turbines, gas compressors, and large scale induction pumps. The sensor transmits ultra-precise, low-noise analog raw signals directly to the Bently Nevada 3500 rack system. This uncompromised telemetry allows the safety system to execute instant emergency shutdown sequences before mechanical degradation causes critical structural failure.

Transducer Suffix Option Breakdown

330103 [3300 XL 8 mm Probe]

Designates the core sensor model as an 8 mm proximity probe utilizing a standard 3/8-24 UNF imperial thread pattern, offering full electrical compatibility with the 3300 XL Proximitor series.

-00 [Unthreaded Length Suffix]

Specifies a 0.0-inch unthreaded barrel configuration, which means the probe casing features complete external threads along its entire shaft length to enable maximum mounting depth adjustments.

-13 [Overall Case Length Suffix]

Defines a 1.3-inch overall case length, providing a compact threaded profile designed for low-clearance bearing housings or short internal mounting brackets.

-10 [Total Length Suffix]

Establishes a 1.0-meter (3.3 feet) integrated coaxial cable length measured from the polyphenylene sulfide sensor tip to the distal miniature coaxial terminal.

-12 [Connector and Cable Option Suffix]

Equips the integrated cable with a fluid-tight, stainless steel flexible armor jacket and includes a miniature coaxial ClickLoc male connector with a factory connector protector.

-05 [Multiple Agency Approvals Suffix]

Certifies the assembly under multiple global hazardous area safety protocols including ATEX, IECEx, and CSA standards for safe operation in intrinsically safe zones.

Mechanical and Electrical Attributes

Site Positioning and Calibration Instructions

During physical field installation, the instrument technician must set the mechanical gap clearance accurately to ensure the sensor operates inside its linear voltage zone. Connect a digital multimeter across the Bently Nevada 3300 XL Proximitor terminal points and adjust the probe depth inside the mounting sleeve until the DC gap voltage reads exactly -10.0 VDC, representing the precise physical center of the linear calibration envelope.

Maintain a strict minimum bend radius of 25.4 mm (1.0 inch) on the armored coaxial cable to eliminate risk of kink damage or attenuation of the high-frequency carrier wave. Route the probe armor through isolated instrument cable trays to shield the sensor line from industrial electromagnetic interference. Technicians must verify that the paired extension cable combines with this 1.0-meter probe to match the specific 5.0-meter or 9.0-meter total system length required by the Proximitor module.

Industrial Survivability and Distributed System Architecture

The advanced design of the 3300 XL probe employs a specialized polyphenylene sulfide (PPS) tip material that forms an airtight, chemically inert shield over the internal coil. This structure resists structural degradation from aggressive synthetic oils, ammonia, and high-pressure steam environments found in severe oil and gas refineries or power generation plants.

The analog output signal generated by the sensor loop integrates directly into the digital monitoring backbone of a Bently Nevada 3500 system. The system mirrors these continuous vibration profiles to automated control interfaces like Honeywell Experion PKS or Siemens S7 controllers via standard analog loops or Modbus communication networks. This system architecture enables plant managers to run advanced predictive maintenance algorithms alongside automated safety interlocks.

Field Instrumentation Troubleshooting Diagnostics

Q1: What unique installation benefit does the -12 armored cable suffix provide in the field?

A1: The -12 suffix provides a flexible stainless steel armor jacket over the entire length of the coaxial cable. This armor provides superior mechanical protection against physical abrasion, flying debris, and sharp bending, and it eliminates the strict requirement for external conduit routing in exposed machinery areas.

Q2: Can this 3300 XL probe connect to an older 7200 series Proximitor system?

A2: No. The 3300 XL series utilizes completely different electrical characteristics, drive frequencies, and coil architectures compared to the legacy 7200 series. Intermixing these generations creates massive scale factor distortion and corrupts your vibration tracking. Always match a 3300 XL probe with a 3300 XL Proximitor.

Q3: How do I identify an electrical short circuit versus an open loop using a digital voltmeter?

A3: When measuring the Proximitor output terminal, a constant reading near 0 VDC typically indicates a direct short circuit in the cable or a probe tip pinned against the shaft target. Conversely, if the multimeter displays a constant maximum saturation reading of -24 VDC, the system loop contains an open circuit fault, indicating a loose ClickLoc connector or a broken core conductor.
