Introduction

The Bently Nevada 330105-05-30-05-02-00 is a 3300 XL 8 mm Reverse Mount Probe intended for non-contact monitoring of rotating shafts in demanding industrial machinery. Built around eddy-current proximity sensing technology, the probe is designed to provide reliable measurements of shaft vibration and radial position without making physical contact with the rotating surface.

Its reverse-mount construction is particularly valuable in machinery where access to the probe target is available from the inside of a bearing housing, casing, or other structural opening. This installation concept can simplify probe positioning while helping engineers work within tight mechanical constraints.

The 05 cable-length configuration provides a compact connection arrangement for installations where the monitoring electronics are located relatively close to the probe. Combined with the Miniature ClickLoc coaxial connector and the non-approved 00 agency configuration, this version is a practical choice for standard industrial installations that do not require additional hazardous-area certification.

For maintenance departments, rotating-equipment specialists, and system integrators, the 330105 series offers a proven platform for building dependable proximity monitoring systems around turbines, compressors, generators, pumps, and other high-value machinery.

Technical Specifications

Advantages

Reverse-Mount Flexibility

The reverse installation principle is the key mechanical advantage of the 330105 family. It allows the sensing assembly to be installed from the opposite side of a machine mounting structure, making it useful in areas where conventional probe access is impractical.

Compact 0.5-Meter Cable

The 0.5-meter cable provides a neat solution for short-distance installations. It avoids unnecessary cable loops and can make routing cleaner around compact bearing housings.

8 mm Proximity Technology

The 8 mm sensing format is a well-established configuration for rotating-shaft measurement. It provides a suitable balance between sensing capability, physical size, and installation flexibility.

Miniature ClickLoc Connector

The 02 connector configuration uses a Miniature ClickLoc coaxial interface. Its compact form is advantageous where instrumentation connections must fit into restricted machinery spaces.

Non-Contact Measurement

The eddy-current principle allows the probe to monitor shaft movement without physical contact. This means there is no probe-to-shaft mechanical wear during normal operation.

Durable Industrial Construction

The probe assembly uses industrial-grade materials designed for demanding machinery environments. The PPS probe tip and stainless-steel case construction provide a robust foundation for long-term monitoring service.

Easy System Expansion

The short integral cable can be combined with an appropriate extension cable when additional system length is required. This gives engineers flexibility when locating the Proximitor Sensor at a convenient position.

Practical Maintenance Choice

A clearly matched replacement probe can reduce commissioning complications and minimize unnecessary modifications to the existing monitoring installation.

Continuous Condition Awareness

Rather than relying exclusively on periodic inspection, a properly installed proximity system can provide continuous shaft information, helping operators recognize developing machinery conditions earlier.
