        Features:

        • Advanced Corrosion Resistance for Aggressive Chemical Environments
        • High-Precision Linear Measurement with System Interchangeability
        • Extreme Temperature Operation and Secure Connectivity
        The Bently Nevada 146054-12-05-02-05 is specifically designed to withstand harsh chemical environments, including anhydrous ammonia (NH₃), ammonium hydroxide (NH₄OH), and hydrogen sulfide (H₂S). Its front-end ceramic-to-metal interface is helium leak-tested to ensure a hermetic seal, preventing aggressive media from entering the probe case. Rated for a pressure of 34 Bar (500 psi), this probe provides long-term, maintenance-free operation in applications where standard probes would quickly fail due to corrosion.

        Bently Nevada 146054-12-05-02-05 features a linear range of 1.52 mm (60 mils) and an incremental scale factor of 7.87 V/mm (200 mV/mil) with an interchangeability error of only ±6.5% across temperatures from 0°C to +45°C. When integrated with the 3300 Proximitor Sensor and extension cables, the Bently Nevada 146054-12-05-02-05 delivers accurate, repeatable measurements of shaft vibration, axial position, and rotational speed. Its predictable electrical characteristics allow for standardized system calibration, reducing installation time and minimizing the risk of measurement errors in critical rotating machinery.

        The Bently Nevada 146054-12-05-02-05 is rated for continuous operation in ambient temperatures from -51°C to +177°C (-60°F to +351°F), making it suitable for both cryogenic compressor applications and high-heat turbine installations. The probe is equipped with gold-plated miniature coaxial ClickLoc connectors, which provide a secure, finger-tight connection that resists loosening in high-vibration environments.

        The 146054-12-05-02-05 Bently Nevada 3300 Ceramic Capped Proximity Probe may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        Description
        The Bently Nevada 146054-12-05-02-05 is purpose-built to withstand corrosive gases and liquids, including anhydrous ammonia (NH₃) and ammonium hydroxide (NH₄OH). Its advanced design incorporates an alumina (ceramic) tip and a 304 stainless steel probe case, providing a robust hermetic seal rated to 34 Bar (500 psi). This construction prevents aggressive media from entering the probe front end, ensuring long-term reliability in the most demanding chemical environments.

        As part of the 3300 proximity probe system, the Bently Nevada 146054-12-05-02-05 offers a linear range of 1.52 mm (60 mils) with an incremental scale factor of 7.87 V/mm (200 mV/mil). It is fully compatible with the 3300 Proximitor Sensor and extension cables, utilizing corrosion-resistant gold-plated ClickLoc connectors for secure, tool-free installation. The probe’s 5-meter total length provides flexibility for remote monitoring setups.

        The Bently Nevada 146054-12-05-02-05 is a forward-mount probe without armor, featuring a 1.2-inch overall case length. Installation requires electrical gapping to avoid physical contact with the target surface, as the ceramic tip cannot withstand direct mechanical loads. The probe operates reliably across a extreme temperature range of -51°C to +177°C (-60°F to +351°F), making it suitable for both cryogenic and high-heat rotating machinery.

        Technical notes
        The Bently Nevada 146054-12-05-02-05 utilizes a shifted linear range compared to standard 3300 XL probes; users must gap the probe electrically and avoid mechanical contact with the target surface. Additionally, this model is not sealed at the rear and should not be exposed to destructive environments such as water or hydrogen sulfide.

        VIEW ALL FAQS
        What are the primary use scenarios for the Bently Nevada 146054-12-05-02-05?
        This probe is specifically designed for monitoring shaft vibration and position in compressors handling aggressive media, such as anhydrous ammonia (NH₃) refrigeration circuits and high-pressure chemical reactors.
        Can Bently Nevada 146054-12-05-02-05 come into physical contact with the target shaft?
        No. The ceramic tip is robust against corrosion but brittle; it must be gapped electrically. Physical contact with the rotating shaft will damage the probe tip.
        How do I handle the shifted linear range during monitor configuration?
        The linear range of this probe is shifted compared to standard XL probes. Extra care is required; the probe tip may contact the shaft before reaching the lower OK limit. A monitor modification may be required for proper configuration.
