Quick Detail

Description

The 330106-05-30-10-02-05 3300 XL 8 mm Reverse Mount Probes represents an engineering solution specifically designed to address the critical challenge of installing vibration and displacement sensors in modern machinery with severe spatial constraints. Manufactured by Bently Nevada in the USA, this specialized Reverse Mount Probe is an integral component of the high-performance 3300 XL monitoring system. Its unique design principle allows for installation from the backside of a mounting surface, such as a bearing housing or machine casing bulkhead. This is a decisive feature for applications where conventional forward-mounting is physically impossible due to a complete lack of radial clearance in front of the target shaft. Utilizing precise eddy-current technology, the probe generates a stable, linear voltage output that is directly proportional to the gap between its sensing tip and the conductive target, enabling accurate measurement of both dynamic radial vibration and static axial position.

This particular model, 330106-05-30-10-02-05, is engineered for durability and reliability in the demanding environments often associated with confined machinery spaces. The probe case is constructed from robust AISI 303 or 304 stainless steel (SST), offering excellent resistance to corrosion and mechanical stress. The sensing tip is made from high-performance Polyphenylene Sulfide (PPS), a material chosen for its superior thermal stability and chemical inertness, ensuring long-term performance when exposed to lubricants and process fluids. A key feature of this configuration is its 0 mm unthreaded length and integrated 1.0-meter standard cable, terminated with a secure Miniature ClickLoc coaxial connector. This provides a ready-to-install assembly, minimizing on-site preparation.

Applications

This 3300 XL 8 mm Reverse Mount Probe is indispensable for monitoring critical rotating equipment where internal design leaves zero radial clearance for a standard sensor. Its primary application is in ultra-compact centrifugal compressors, high-speed turboexpanders, and integrated motor-driven pumps used in the oil & gas and process industries. The probe can be installed from within the bearing housing or through a dedicated bulkhead, allowing accurate measurement of shaft vibration and position to detect imbalance or misalignment, even in machinery where the shaft is completely shrouded by adjacent components.

The probe is ideally suited for retrofit and upgrade projects on legacy machinery that originally featured reverse-mount transducers. Its design allows it to directly replace older, often obsolete, sensors without modifying the existing mounting geometry. This is critical for extending the operational life and monitoring capabilities of aging but vital assets in power generation and industrial plants, providing a plug-and-play upgrade to the modern 3300 XL system performance while respecting the original, space-constrained mechanical design.

For applications requiring monitoring from within a sealed or pressurized enclosure, such as the interior of a gearbox or a process gas compressor casing, this reverse-mount configuration is essential. It enables the probe body and its electrical connections to be located in a more accessible or environmentally protected area outside the main chamber, while the sensing tip protrudes through a sealed port to take measurements. This protects the sensor's electronics and cable termination from harsh internal conditions like high-pressure oil mist or corrosive gases.

Competitive Advantage

1. Unique Backside Installation for Zero-Clearance Scenarios

The fundamental advantage of this probe is its reverse-mount design, engineered specifically for applications where conventional sensor installation is geometrically impossible. It installs from the rear of a mounting surface, solving the critical challenge of monitoring shafts in ultra-compact machinery, such as hermetically sealed compressors and integrated drive systems, where no frontal access exists. This unlocks condition monitoring capabilities for a class of equipment previously considered "unmonitorable" with standard probes.

2. Hazardous Area Certified for High-Risk Industrial Deployment

This probe configuration comes pre-certified with CSA, ATEX, and IECEx approvals, a comprehensive safety package for global deployment. This allows for direct and compliant installation in Zone 1/2 hazardous areas, which is a mandatory requirement for many applications in the petrochemical, offshore, and pharmaceutical industries. It eliminates the project delays and additional costs associated with obtaining equipment certifications, providing a ready-to-use solution for high-risk environments.

3. Robust, Maintenance-Free Construction for Inaccessible Locations

Built with a stainless steel (SST) housing and a PPS tip, the probe is designed to survive the harsh conditions typical of cramped, hard-to-access machinery interiors—exposure to heat, oil, vibration, and chemical wash. Its rugged, sealed construction ensures long-term reliability and minimizes the need for maintenance or replacement in locations where service access is extremely difficult or requires extensive machine disassembly, thereby significantly reducing lifecycle costs and downtime risks.
