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

Description

An unthreaded length of 5.0 mm (Option 05) paired with a 30 mm case length (Option 30) and a 1.5 m (4.9 ft) total cable length (Option 15) defines the specific configuration of this reverse mount probe — 330106-05-30-15-02-05. The Bently Nevada 3300 XL 8 mm reverse mount proximity probe features M10 x 1 threads and is used with the 3300 XL Proximitor sensor and extension cables for non-contact machinery displacement and vibration measurements. In contrast to standard-mount configurations, the reverse mount design allows installation through the machine housing or sleeve, facilitating access in confined mechanical spaces where external threading is impractical.

This specific configuration incorporates a miniature coaxial ClickLoc connector with a standard cable (Option 02) and carries CSA, ATEX, and IECEx approvals for hazardous areas (Option 05). It operates as part of the 3300 XL 8 mm transducer system, generating an electrical signal directly proportional to the gap distance between the probe tip and the observed target. This signal is routed back to machinery protection monitors for real-time tracking of parameters such as radial shaft vibration and axial thrust position.

Features

• M10 x 1 metric thread configuration with 30 mm case length (Option 30) and 5.0 mm unthreaded length (Option 05)
• 1.5-meter (4.9-foot) integrated standard coaxial cable (Option 15) for immediate link to extension cabling
• Miniature ClickLoc coaxial connector (Option 02) provides secure electrical attachment
• Agency approval package (Option 05) includes CSA, ATEX, and IECEx certifications for hazardous area installation
• Reverse mount body design allows rear-entry installation through sleeves or machine casings

Applications

This reverse mount proximity probe is used for non-contact machinery protection and vibration monitoring. Common industrial applications include:

• Radial shaft vibration measurement on high-speed turbomachinery
• Axial rotor thrust position tracking in steam and gas turbines
• Eccentricity and phase reference (Keyphasor) monitoring on rotating shafts
• Sleeve-bearing clearance measurements in industrial compressors, pumps, and generators

Technical Specifications

Installation Guidelines

Proper installation of the reverse mount probe is critical for accurate measurements and system longevity:

• Thread Engagement: Maximum thread engagement for M10 x 1 threads is 15 mm. Avoid exceeding this limit to prevent mechanical binding during insertion.
• Torque Limits: Do not exceed the recommended tightening torque during installation to avoid damaging the M10 threads or probe casing.
• Connector Handling: ClickLoc connectors must be kept clean and dry. Finger-tighten the gold coaxial connectors securely. Do not use tools on the gold-plated connectors unless explicitly instructed.
• Cable Routing: Observe the minimum bend radius of the coaxial cable to prevent attenuation or damage to the internal conductor. Route cables through protective conduit where mechanical damage or fluid exposure is possible.

The 330106-05-30-15-02-05 configuration holds the following industrial and safety certifications under the Option 05 designation:

• CSA: Certified for Class I, Division 1 and 2 hazardous locations
• ATEX: Category 1G / 3G, Zone 0 and Zone 2 explosive environments
• IECEx: Certified for international intrinsic safety and non-incendive environments
• CE: Declared compliant with relevant European safety and electromagnetic compatibility standards
