Bently Nevada 146055-50-02-05 3300 Ceramic Capped Reverse Mount Probe

Product Introduction

When unplanned downtime strikes rotating machinery, accurate vibration measurement is critical for early fault detection. The Bently Nevada 146055-50-02-05 3300 Ceramic Capped Reverse Mount Probe delivers reliable, continuous monitoring in harsh industrial environments. This eddy-current probe is part of the trusted 3300 series, designed for non-contact displacement measurements on shafts and bearings. With a 5.0-meter integral cable and 3/8-24 UNF threads, it integrates seamlessly into existing condition monitoring systems.

Technical Specifications Breakdown

The 146055-50-02-05 features a total length option of 5.0 meters (16.4 feet), providing flexibility for installation in tight or remote locations. The probe case thread is 3/8-24, ensuring secure mounting. The connector and cable-type option is 02, which includes a Miniature ClickLoc coaxial connector with standard cable. The agency approval option is -05, indicating multiple approvals for global use. The probe tip is made of alumina ceramic (Al2O3), offering excellent wear resistance and stability. The probe case is constructed from AISI 304 stainless steel, providing corrosion resistance in demanding environments. The operating and storage temperature range is -51°C to +177°C (-60°F to +351°F), suitable for extreme conditions.

Industry Applications

This probe is ideal for monitoring critical rotating equipment such as steam turbines, compressors, and large motors. In a power generation plant, the 146055-50-02-05 can detect shaft vibration and eccentricity, enabling predictive maintenance and preventing catastrophic failures. In oil and gas facilities, it monitors centrifugal pumps and gearboxes, reducing unplanned shutdowns. The ceramic capped design offers enhanced durability in abrasive or high-temperature environments, making it a cost-effective choice for long-term reliability.

Installation & Setup Guidance

Proper installation is key to accurate readings. Ensure the probe tip is positioned within the linear range of 0.25 to 1.78 mm from the target. The maximum thread engagement is 0.563 inches. Use the 3/8-24 UNF threads to mount the probe securely in a mounting block or bracket. The 5.0-meter cable should be routed away from high-EMI sources and sharp edges. For best performance, pair this probe with a compatible 3300 Proximitor Sensor and extension cable. Always verify the target material is AISI 4140 steel for calibration accuracy.

Maintenance & Reliability

Regular inspection of the probe cable and connector prevents signal degradation. Check for physical damage to the ceramic tip and stainless steel case. The probe is rated to seal 34 Bar (500 psi) nitrogen, making it suitable for pressurized applications. For high-pressure environments, contact Bently Nevada for modifications. The 12-month factory warranty provides peace of mind. To maximize service life, avoid exceeding the temperature limits and ensure proper grounding.

Selection Guide & Purchasing Advice

When ordering the 146055-50-02-05, confirm your system requirements: total length (5.0 m), connector type (Miniature ClickLoc), and agency approvals (multiple). This probe is designed for use with 5 m Proximitor Sensors only. For complete technical specifications, contact BluePLC Industrial. We stock new and original factory-packed units with full warranty.
