What Is the Bently Nevada 146054-08-05-00-00?
When vibration monitoring in rotating machinery demands precision and reliability, the Bently Nevada 146054-08-05-00-00 delivers. This 3300 Ceramic Capped Proximity Probe measures shaft displacement and vibration in critical assets like turbines, compressors, and pumps. With a 3/8-24 UNF thread and no connector, it integrates seamlessly into existing 3300 XL systems.
Technical Specifications Breakdown
The 146054-08-05-00-00 offers key specs that ensure accurate, repeatable measurements. The overall case length is 0.8 inches (option -08), and the total probe length is 0.5 meter (1.6 feet, option -05). The probe case thread is 3/8-24, with a maximum thread engagement length of 0.563 inches. Nominal DC resistance from center to outer conductor is 7.45 ± 0.50 ohms for the 0.5 meter probe. The linear range spans 1.52 mm (60 mils), starting at approximately 0.25 mm (10 mils) from the target and extending to 1.78 mm (70 mils), corresponding to -4 to -16 Vdc. Incremental scale factor (ISF) for a standard 5- or 9-meter system is 7.87 V/mm (200 mV/mil) ±6.5% over the full linear range from 0°C to +45°C (+32°F to +113°F). The probe tip is alumina ceramic (Al2O3), and the case is AISI 304 stainless steel. The standard cable is 75 Ω coaxial FEP insulated, available in 0.5, 1, 2, 5, or 9 meter lengths. Operating and storage temperature range is -51°C to +177°C (-60°F to +351°F). The probe is rated to seal 34 Bar (500 psi) nitrogen.
Industry Applications
In power generation, the 146054-08-05-00-00 monitors turbine shaft vibration and thrust position, preventing costly unplanned outages. In oil and gas, it tracks compressor and pump health, enabling predictive maintenance. Its ceramic tip and stainless steel case withstand harsh environments, while the wide temperature range suits both indoor and outdoor installations.
Installation & Setup Guidance
Mount the probe with the 3/8-24 UNF thread into a pre-drilled hole, ensuring the tip faces the target surface perpendicularly. Use the specified maximum thread engagement of 0.563 inches to avoid mechanical interference. Connect the coaxial cable to a compatible Bently Nevada Proximitor sensor and extension cable. For optimal linearity, maintain an air gap between 0.25 mm and 1.78 mm from the target. Calibrate the system using an AISI 4140 steel target for best accuracy.
Maintenance & Reliability
Inspect the probe cable and connector periodically for wear or damage. Keep the ceramic tip clean and free of debris. The probe's robust construction—alumina ceramic tip and stainless steel case—ensures long service life in demanding conditions. For highest reliability, follow the manufacturer's recommended inspection intervals and environmental guidelines.
Compatibility & Integration
This probe is designed for 3300 XL systems using Bently Nevada Proximitor sensors and extension cables. It works with standard 5- or 9-meter systems. The no-connector option (option -00) simplifies integration in applications where a direct cable connection is preferred. Always verify system compatibility before ordering.
Selection Guide & Purchasing Advice
Before purchasing the 146054-08-05-00-00, confirm your required probe length, case length, and connector type. This model suits applications needing a 0.5 meter cable and no connector. For different lengths or connectors, refer to the 146054 ordering code. SpareTechPLC stocks new, original Bently Nevada parts with full factory warranty.
