Information

Overview Manuals Mechanical Arrangement Modification Control System Compatibility

Features:

  • Uses an alumina ceramic sensing cap for demanding chemical environments
  • Front ceramic-to-metal interface is helium leak-tested and rated to 34 bar.
  • Configured with a 2.0 m total probe length and miniature coaxial ClickLoc connection.
The Bently Nevada 146054-058-20-02-05 MOD:173931-011-058 is a specialized member of the 3300 Ceramic Capped Probe family. Bently Nevada developed the 146054 series for installations in which the front of the probe-case assembly can be exposed to corrosive gases or liquids. The alumina ceramic cap and 304 stainless-steel case provide additional protection for demanding applications such as anhydrous ammonia and other extreme-pH environments.

The ceramic-to-metal front interface is helium leak-tested by Bently Nevada to establish a hermetic seal, while the standard ceramic-capped design is rated to 34 bar (500 psi). The probe is intended to operate as part of a compatible 3300 proximity-monitoring system using the appropriate Proximitor Sensor and extension cable.

The 146054-058-20-02-05 MOD:173931-011-058 Bently Nevada 3300 Proximity Probe may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
Bently Nevada 146054-058-20-02-05 MOD:173931-011-058 3300 Proximity Probe Manuals(Datasheets), Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The 146054 base configuration uses a 3/8-24 UNF 2A mounting thread. The OEM drawing identifies approximately 7.0 mm and 7.2 mm body diameters, while the standard ordering structure permits different case lengths and total cable lengths.
The MOD:173931-011-058 designation is important when replacing this probe. The publicly available OEM datasheet does not provide a decoding table for this specific modification number, so its mechanical or application-specific characteristics should be preserved exactly when sourcing a replacement rather than substituted based only on the standard 146054 ordering code.
The 3300 Ceramic Capped Probe is compatible with the 3300 Proximitor Sensor and extension cable. The probe, cable, and Proximitor Sensor should therefore be treated as a complete measurement chain when checking replacement compatibility.

Technical notes

The technical specifications for this model are clearly defined: the base model "146054" designates a ceramic probe featuring a 3/8-24 UNF fully threaded housing without external armor protection. Its sensing tip utilizes a high-purity alumina (Al₂O₃) ceramic cap, hermetically sealed via vacuum brazing. It comes equipped with an integrated shielded cable (2.0 m / 6.6 ft), a Miniature coaxial ClickLoc™ connector (-02), and holds high-level multi-national explosion-proof certifications—CSA, ATEX, and IECEx (-05).

Ceramic-Barrier Protection

The Bently Nevada 146054-058-20-02-05 MOD:173931-011-058 belongs to the 3300 Ceramic Capped Probe family, developed for machinery monitoring in aggressive chemical and high-pressure environments. The manufacturer specifies an alumina ceramic cap and 304 stainless-steel probe case to provide protection in applications involving corrosive gases and liquids, including anhydrous ammonia and other extreme-pH environments.

Hermetic Front-End Sensing

Bently Nevada helium leak-tests the ceramic-to-metal interface to provide a hermetic front-end seal, and the ceramic-capped probes are rated for 34 bar (500 psi) at the pressure-sealing interface. The probe is compatible with the 3300 Proximitor Sensor and extension cable as part of the complete proximity-monitoring system.

PRODUCT & ORDER FAQS

Questions buyers ask about 146054-058-20-02-05 MOD:173931-011-058

  • How should the complete 146054-058-20-02-05 configuration be identified?

    The Bently Nevada 146054-058-20-02-05 is a 3300 Ceramic Capped Probe with a 3/8-24 UNF thread and no armor. The ordering structure specifies a 5.8-inch overall case length, 2.0 m (6.6 ft) total probe length, miniature coaxial ClickLoc connector with standard cable, and the CSA/ATEX/IECEx approval option. The additional MOD: 173931-011-058 should be retained when identifying or replacing the installed unit because the modification number is part of the supplied configuration.
  • Will this 2-meter ceramic probe work with my existing 3300 proximity system?

    The 146054 ceramic-capped probe is designed for the 3300 proximity transducer system and is compatible with the 3300 Proximitor Sensor and extension cable. Because this particular unit is 20, its total probe length is 2.0 m; the complete probe/extension-cable/Proximitor arrangement should therefore be checked as a system before replacement. The ceramic-capped probe should not be treated as an interchangeable substitute for every standard 3300 probe without checking the system calibration and application requirements.
  • Why would an engineer specify this ceramic-capped version instead of a conventional proximity probe?

    The ceramic cap is the key application feature. Bently Nevada developed the 146054 family for installations where the front of the probe is exposed to corrosive gases or liquids, including aggressive chemical and extreme-pH environments. The alumina ceramic cap and stainless-steel probe case provide protection at the sensing end, and the manufacturer states that the ceramic-to-metal interface is helium leak-tested to provide a hermetic seal.
  • What installation dimensions and gap should be observed for the 146054-058 version?

    The probe uses a 3/8-24 UNF mounting thread, and this configuration has a relatively long 5.8-inch case. Bently Nevada specifies a maximum thread engagement of 0.563 in for the 3/8-24 configuration. For electrical setup, the recommended probe gap is 1.0 mm (40 mils), with the ceramic-capped system having a linear range of approximately 1.52 mm (60 mils). The ceramic tip should not be allowed to contact the shaft during installation or operation.
  • What environmental conditions make this particular probe useful?

    The 3300 Ceramic Capped Probe is intended for demanding chemical and pressure applications, with the manufacturer specifying a 34 bar (500 psi) pressure rating for the ceramic-capped probes. However, the 146054 design seals the front end only. Its rear is not sealed, so the rear portion must not be exposed to destructive media such as water, NH3, NH4OH, or hydrogen sulfide. This distinction is important when selecting the mounting location and routing the cable.
  • Is the 146054-058-20-02-05 MOD: 173931-011-058 supplied as new and original?

    Yes. Moore Automated supplies new and original products with a one-year warranty. For this configuration-specific Bently Nevada probe, we can also provide actual product photographs and available technical manuals before purchase, allowing the customer to compare the ceramic tip, 5.8-inch case configuration, connector, cable length, and identification markings with the existing installation.
  • Can you confirm stock and provide the required certificates for this modified configuration?

    We can check inventory specifically against the complete 146054-058-20-02-05 / MOD: 173931-011-058 identification rather than treating another 146054 variant as equivalent. Available supplier documentation can include COO, COC, test reports, and a warranty letter. For applicable Bently Nevada products, Moore Automated can also provide available COO, DOC, COC, testing, and calibration certificates; when requested documentation is available, it can be packed with the goods. If you are ready to purchase, we can also check whether a special discount is available. Providing your target price can help us apply for a discount more efficiently.
  • How can you ship this probe, and are you a Bently Nevada authorized agent?

    DHL and FedEx door-to-door delivery are supported. Moore Automated is not a Bently Nevada authorized agent, but we supply the same branded products through our sourcing channels. Before dispatch, we can confirm the complete 146054-058-20-02-05 part number and MOD: 173931-011-058, together with available photographs and documentation, so the customer can verify the required 5.8-inch case, 2.0 m probe length, ClickLoc connector, and CSA/ATEX/IECEx configuration. Bently Nevada also provides customer-care and technical-support resources for product and part-number verification.
