Bently Nevada 330101-00-28-10-02-CN 3300 XL 8 mm Proximity Probes

Product Overview

The 330101-00-28-10-02-CN is a 3300 XL 8 mm Proximity Probe manufactured by Bently Nevada, designed for high-performance vibration and position monitoring in critical rotating machinery. As part of the 3300 XL transducer system, this probe provides a linear output voltage proportional to the distance between the probe tip and the observed conductive target (typically a shaft). This specific configuration features a non-threaded 0.0-inch length with a 2.8-inch overall case length and a 1.0-meter total cable length. The "CN" suffix indicates compliance with country-specific agency approvals for hazardous area installations. These probes are fundamental components for the 3500 and 3300 Monitoring Systems, commonly applied in steam turbines, centrifugal compressors, and industrial pumps to detect radial vibration, axial thrust, and phase reference (Keyphasor) measurements.

Technical Configuration

The 3300 XL 8 mm system is engineered for interchangeability between probes, extension cables, and Proximitor sensors without requiring individual calibration.

• Probe Tip Material: Polyphenylene sulfide (PPS) for chemical and thermal resistance.

• Case Material: AISI 303 or 304 Stainless Steel (SST).

• Cable Construction: 75 $\Omega$ miniature coaxial cable with ClickLoc gold-plated connectors.

• Environmental Sealing: Designed to withstand high-pressure lubricants and moisture ingress at the probe-to-extension cable connection.

Technical Specifications

Ordering Information

Industrial procurement should reference the complete part number string to ensure physical compatibility with mounting brackets and extension cables.

• Part Number: 330101-00-28-10-02-CN

• Series: 3300 XL Transducer System

• Mandatory Complementary Parts: Requires 3300 XL Extension Cable and 3300 XL Proximitor Sensor for a complete measurement loop.

Engineering & Installation Guide

Successful deployment of proximity probes requires strict adherence to mechanical clearances and electrical shielding protocols.

• Cross-talk Prevention: When installing multiple probes in a single bearing housing, maintain a minimum separation distance to prevent magnetic field interference (cross-talk) between probe tips.

• Target Material Calibration: These probes are calibrated for AISI 4140 steel targets. Using other materials (e.g., stainless steel or aluminum) will significantly alter the scale factor and linearity.

• Cable Protection: Utilize flexible or rigid conduit to protect the coaxial cable from mechanical damage. Avoid tight bends; the minimum bend radius for standard 3300 XL cable is 25.4 mm (1.0 in).

• Connector Integrity: The ClickLoc connector must be clean and dry. Fingerprints or oil on the center pin can cause signal instability. It is recommended to use silicone connector protectors or heat-shrink tubing in oily environments.

FAQ

• Can the 3300 XL 8 mm probe replace an older 3300 8 mm probe?

  Yes, the 3300 XL 8 mm system is backward compatible with non-XL 3300 8 mm components, though performance is optimized when using a full XL-series loop.

• What does the "CN" approval specify?

  The "CN" suffix confirms the unit meets specific regional regulatory requirements for hazardous area electrical equipment, often involving Ex or intrinsic safety certifications.

• How is the "Total Length" calculated?

  The 1.0-meter length includes the probe lead and the integral cable. This must match the Proximitor sensor's calibrated length (typically 5.0m or 9.0m systems).
