Bently Nevada 146054-08-20-01-05 3300 Ceramic Capped Proximity Probe

Product Introduction

When monitoring critical rotating machinery, reliable vibration and position sensing is non-negotiable. The Bently Nevada 146054-08-20-01-05 is a 3300 Ceramic Capped Proximity Probe designed for precise, contactless measurement of shaft displacement and vibration. This probe uses a 3/8-24 UNF thread and is supplied without armor, making it suitable for standard industrial environments where robust performance is required. As part of the trusted 3300 series, this component delivers the accuracy and durability that engineers expect from Bently Nevada.

Technical Specifications Breakdown

The 146054-08-20-01-05 offers a 0.8-inch overall case length and a total probe length of 2.0 meters (6.6 feet), providing flexibility for installation in tight or remote locations. The probe case thread is 3/8-24, with a maximum thread engagement of 0.563 inches, ensuring secure mounting. The probe features a miniature coaxial ClickLoc connector with a connector protector, simplifying field connection and reducing signal loss. Agency approvals include CSA, ATEX, and IECEx, confirming its suitability for hazardous area applications. The nominal DC resistance from the center conductor to the outer conductor is 7.88 ± 0.50 ohms for the 2.0-meter probe length.

Industry Applications

This proximity probe is ideal for monitoring radial vibration and axial position in turbines, compressors, pumps, and other rotating equipment. In petrochemical plants, the ATEX and IECEx certifications allow installation in explosive atmospheres without compromising safety. For power generation facilities, the probe's ceramic tip provides excellent wear resistance and consistent performance over extended operating cycles. The 146054-08-20-01-05 integrates seamlessly with Bently Nevada monitoring systems to deliver real-time data for predictive maintenance and machine protection.

Installation & Setup Guidance

When installing the 146054-08-20-01-05, ensure the target surface is clean and made of AISI 4140 steel for optimal performance. The linear range begins at approximately 0.25 mm (10 mils) from the target and extends to 1.78 mm (70 mils), corresponding to an output of approximately -4 to -16 Vdc. Use the 3/8-24 UNF thread to mount the probe securely, and verify that the thread engagement does not exceed 0.563 inches to avoid mechanical interference. Connect the miniature coaxial ClickLoc connector to the extension cable, ensuring a positive lock to maintain signal integrity.

Maintenance & Reliability

The 3300 ceramic capped probe is built for long service life in demanding conditions. The probe case is made of AISI 304 stainless steel, offering corrosion resistance, while the alumina ceramic tip withstands high temperatures up to +177°C (+351°F) during operation. The probe is rated to seal 34 Bar (500 psi) nitrogen, making it suitable for pressurized environments. Regular inspection of the cable and connector for damage is recommended.
