Product Overview

The Bently Nevada 330910-00-13-10-02-00 3300 XL 8mm Proximity Probe provides critical displacement and vibration measurements for high-speed rotating machinery. As a cornerstone of Turbine Supervisory Instrumentation (TSI), this eddy current sensor delivers continuous, high-accuracy telemetry to the Bently Nevada 3500 monitoring system or integrated DCS architectures.

Engineers rely on this specific probe configuration to monitor fluid-film bearing clearances, detect shaft unbalance, and prevent catastrophic mechanical failures in severe industrial environments. The rugged design withstands extreme temperature cycles and corrosive lubricants, ensuring uninterrupted asset protection and supporting automated emergency shutdown protocols.

Suffix Parameter Breakdown

330910 [Unthreaded Probe]

This designation specifies an NSv (No-Smooth) style unthreaded 8mm probe body, ideal for specialized clamp mounting brackets or internal machine housings where standard thread-in profiles are restricted.

-00 [Unthreaded Length Options]

Specifies a 0mm unthreaded length, meaning the smooth probe barrel configuration relies entirely on the primary mounting body selection for physical depth positioning.

-13 [Overall Case Length]

Indicates a total case length of 1.3 inches, optimizing physical clearance inside tight bearing housings or specialized sensor brackets.

-10 [Total Length Option]

Defines a 1.0-meter (3.3 feet) total cable length, measured from the probe tip to the male miniature coaxial connector.

-02 [Connector and Cable Option]

Configures the assembly with a miniature coaxial click-loc connector and includes standard cable construction without additional armor plating.

-00 [Agency Approval Option]

Supplied with standard non-hazardous area certifications, suitable for general industrial deployments requiring standard factory calibration compliance.

Physical & Operational Specifications

Field Deployment & Calibration Guidelines

Field technicians must verify the physical gap voltage during mechanical installation using a calibrated digital multimeter. Connect the meter to the Proximitor Sensor test points and adjust the probe position until the DC gap voltage reads approximately -10.0 VDC, corresponding to the center of the linear calibrated range.

Maintain a strict minimum bend radius of 25.4 mm (1.0 inch) for the coaxial cable during routing to prevent internal conductor degradation or impedance shifts. Always use matching 3300 XL extension cables and Proximitor sensors to ensure total system length equals exactly 5.0 or 9.0 meters according to your Proximitor configuration. Isolate all coaxial connections inside a dedicated, grounded conduit box to eliminate external electromagnetic interference and prevent moisture ingress.

Industrial Survivability & System Integration

This 3300 XL probe utilizes premium polyphenylene sulfide (PPS) tip material, injection-molded over the internal sensing coil to establish an airtight, chemical-resistant barrier. The advanced design resists degradation from synthetic lubricants, ammonia, and high-pressure steam cycles typical in power generation and petrochemical processing facilities.

The sensor integrates directly with the Bently Nevada 3500/42M Proximitor Monitor module, delivering raw analog signals that can be simultaneous mirrored to Honeywell Experion PKS or Siemens S7 systems via Modbus TCP or OPC UA interfaces. This dual-layer visibility supports both real-time safety interlocks and deep predictive maintenance analytics.

Technical Validation Diagnostics

Q1: Can I connect this 1.0-meter probe directly to a 3500 monitor without an extension cable?

A1: No. The 3300 XL Proximitor Sensor requires a specific total system length of either 5.0 meters or 9.0 meters to function within calibrated scale factor tolerances. You must install a matching 3300 XL extension cable (such as a 4.0-meter cable to achieve a 5.0-meter system) between the probe and the Proximitor.

Q2: What are the exact structural differences indicated by the -02 cable option?

A2: The -02 suffix denotes a standard coaxial cable fitted with a click-loc miniature connector, supplied without flexible stainless steel armor. If your application routes cables through open machinery paths prone to mechanical abrasion or flying debris, you should select a configuration with an armored cable suffix.

Q3: How do I identify if the probe tip or the cable is faulted during routine maintenance?

A3: Measure the resistance between the center pin and the outer shield of the click-loc connector using a digital multimeter. For a 1.0-meter probe, the standard center-to-shield resistance should register between 5.9 and 7.7 ohms. A reading near zero indicates a short circuit, while an infinite reading indicates a broken internal conductor.
