Bently Nevada 146055-05-02-05 3300 Ceramic Capped Reverse Mount Probe

Product Overview

When machinery vibration threatens uptime, the Bently Nevada 146055-05-02-05 3300 Ceramic Capped Reverse Mount Probe provides reliable measurement. This probe is part of the 3300 series, designed for precision monitoring in harsh industrial environments. It features a 0.5 meter (1.6 feet) total length, 3/8-24 UNF threads, and a miniature ClickLoc coaxial connector with standard cable. The probe comes new and original in factory packing, backed by a 12-month factory warranty.

Technical Specifications Breakdown

The 146055-05-02-05 offers key specifications that ensure accurate performance. The probe case thread is 3/8-24, with a maximum thread engagement length of 0.563 inches. The probe nominal DC resistance from the center conductor to the outer conductor is 7.45 ± 0.50 ohms for the 0.5 meter length. The linear range spans 1.52 mm (60 mils), beginning at approximately 0.25 mm (10 mils) from the target and extending to 1.78 mm (70 mils). The incremental scale factor (ISF) for a standard 5-meter or 9-meter system is 7.87 V/mm (200 mV/mil) with ±6.5% interchangeability error over the 60 mil linear range from 0°C to +45°C. The probe tip material is alumina ceramic (Al2O3), and the probe case is AISI 304 stainless steel. The standard cable is 75 Ω coaxial, fluoroethylene propylene (FEP) insulated, available in lengths of 0.5, 1, 2, 5, or 9 meters. The operating and storage temperature range is -51°C to +177°C (-60°F to +351°F), and the probe is rated to seal 34 Bar (500 psi) nitrogen.

Industry Applications

This probe excels in vibration monitoring for rotating machinery such as turbines, compressors, and pumps. In a typical power generation plant, the 146055-05-02-05 mounts in a reverse configuration to measure shaft vibration with high accuracy. Its ceramic tip withstands high temperatures and pressure, making it suitable for steam turbine applications. Compared to standard probes, the ceramic capped design offers enhanced durability in abrasive environments, reducing replacement frequency and maintenance costs.

Installation & Setup Guidance

Install the 146055-05-02-05 with the 3/8-24 UNF thread into a properly tapped hole. Ensure the probe tip is positioned within the linear range of 0.25 to 1.78 mm from the target. Use the miniature ClickLoc connector to attach the extension cable securely. For optimal performance, calibrate the system with an AISI 4140 steel target as specified. Verify the cable length matches your system requirements—available options include 0.5, 1, 2, 5, or 9 meters.

Maintenance & Reliability

Regular inspection of the probe cable and connector ensures reliable operation. Check for physical damage to the ceramic tip and stainless steel case. The probe operates reliably across a wide temperature range (-51°C to +177°C) and withstands pressure up to 34 Bar. For high-pressure applications, contact the custom design department for modifications. Routine verification of the DC resistance (7.45 ± 0.50 ohms) helps detect cable or connector issues early.

Selection Guide & Purchasing Advice

When ordering, confirm the total length option (A = -05 for 0.5 meter), connector type (B = 02 for miniature ClickLoc), and agency approval (C = -05 for multiple approvals). The 146055-05-02-05 is available new and original from BluePLC Industrial. For complete technical specifications, please contact BluePLC Industrial.
