Bently Nevada 330106-05-30-15-02-00 3300 XL 8 mm Reverse Mount Proximity Probe

The Bently Nevada 330106-05-30-15-02-00 is a 3300 XL 8 mm reverse mount proximity probe designed for non-contact shaft displacement and vibration measurements in rotating machinery. This configuration features an M10 x 1 threaded reverse-mount probe, a 1.5 m armored cable, and a miniature ClickLoc coaxial connector. It is intended for use as part of a complete 3300 XL transducer system with a matching extension cable and Proximitor sensor.

Model Configuration

The ordering code defines the probe's mechanical dimensions, cable arrangement, and certification option.

• 330106: 3300 XL 8 mm Reverse Mount Proximity Probe, M10 x 1 thread

• 05: 50 mm unthreaded length

• 30: 3.0 in (approximately 76 mm) case length

• 15: 1.5 m (approximately 4.9 ft) integral cable with stainless steel armor

• 02: Miniature ClickLoc coaxial connector

• 00: No hazardous-area or agency approval option specified

Correct ordering-code verification is important when replacing probes to maintain mechanical fit and system calibration.

Measurement Principle

The probe uses eddy current technology to detect the distance between the probe tip and a conductive target surface without physical contact. When installed with the corresponding 3300 XL extension cable and Proximitor sensor, the transducer system produces an output voltage proportional to the gap between the probe tip and the monitored metal surface.

Typical measurement functions include:

• Radial shaft vibration

• Axial position monitoring

• Differential expansion measurement

• Rotational speed sensing

• Keyphasor phase reference applications

Construction Materials

The probe tip incorporates PPS (polyphenylene sulfide) insulation material, selected for its resistance to wear, chemicals, and elevated operating temperatures.

The probe case is manufactured from AISI 303 or AISI 304 stainless steel, providing mechanical durability and corrosion resistance for industrial machinery installations.

System Compatibility

This probe is designed to operate only as part of a complete 3300 XL transducer system. Performance specifications are achieved when the probe is paired with the specified 3300 XL extension cable and corresponding 3300 XL Proximitor sensor.

Because probe, cable, and Proximitor characteristics are calibrated as a system, replacement components should be selected according to the full ordering code rather than by probe diameter alone.

Technical Specifications

Installation Considerations

The reverse-mount configuration is intended for installations where the probe body is mounted from the rear side of the machine bracket or probe holder. Sufficient clearance should be verified for both the probe body and the armored cable assembly before installation.

Frequently Asked Questions

Q: Can the 330106-05-30-15-02-00 be connected directly to a monitoring system input?
A: No. The probe must be used with the appropriate 3300 XL extension cable and 3300 XL Proximitor sensor. The complete transducer system generates the calibrated output signal.

Q: What is the purpose of the armored cable option?
A: The armored cable provides additional mechanical protection against abrasion, cable movement, and physical damage in machinery installation environments.

Q: What does the 00 approval option indicate?
A: The 00 suffix indicates that no specific hazardous-area or agency approval option is included in this ordering configuration. Approval requirements should be verified against the installation specification.
