Product Overview
When machinery reliability is non-negotiable, the Bently Nevada 146054-08-50-01-00 3300 Ceramic Capped Proximity Probe delivers precise vibration and position measurements. This probe is part of the 3300 series, designed for use with 5 m Proximitor Sensors. The 146054-08-50-01-00 features a 3/8-24 UNF thread case, a 0.8 in overall case length, and a 5.0 meter cable terminated with a miniature coaxial ClickLoc connector and connector protector. Its alumina ceramic tip withstands harsh environments, making it a trusted choice for critical rotating machinery.
Technical Specifications Breakdown
The 146054-08-50-01-00 operates within a linear range of 1.52 mm (60 mils), starting at approximately 0.25 mm (10 mils) from the target. The incremental scale factor (ISF) is 7.87 V/mm (200 mV/mil) ±6.5% over the full linear range, ensuring accurate displacement readings. The probe case is made of AISI 304 stainless steel, and the tip is alumina ceramic (Al₂O₃). The standard cable is 75 Ω coaxial, FEP-insulated, available in lengths including 5.0 meters. The probe temperature range spans -51°C to +177°C (-60°F to +351°F) for both operating and storage. It is pressure-rated to seal 34 Bar (500 psi) nitrogen. The nominal DC resistance from center conductor to outer conductor is 8.73 ± 0.70 ohms for the 5.0 m probe.
Industry Applications
This proximity probe excels in turbomachinery monitoring, including steam turbines, gas turbines, compressors, and pumps. Its ceramic tip resists wear and contamination, making it suitable for high-speed rotating shafts where precise gap measurement is critical. The wide temperature range allows installation in hot zones near bearings or steam paths. The 146054-08-50-01-00 integrates seamlessly into existing 3300 XL monitoring systems, providing reliable data for predictive maintenance programs.
Installation & Setup Guidance
Mount the probe using the 3/8-24 UNF thread, ensuring the maximum thread engagement of 0.563 in is not exceeded. The probe should be positioned so that the target surface is within the linear range (0.25 to 1.78 mm from the probe tip). Use only the 5 m Proximitor Sensor designed for this cable length. Secure the miniature coaxial ClickLoc connector firmly and protect the cable from abrasion. Verify the system calibration with an AISI 4140 steel target for optimal accuracy.
Maintenance & Reliability
The ceramic-capped design minimizes tip wear, extending service life. Periodically inspect the probe cable and connector for damage. The FEP-insulated coaxial cable resists chemicals and high temperatures. The stainless steel case provides corrosion resistance in demanding environments. Regular calibration checks against the specified ISF ensure measurement integrity. The 146054-08-50-01-00 is built for long-term reliability, reducing unplanned downtime.
Compatibility & Integration
This probe is designed for use with the 3300 XL 5 m Proximitor Sensor and extension cables. It is a direct replacement for existing 3300 series probes with the same configuration. The miniature coaxial ClickLoc connector ensures a secure, quick connection. The system performance specifications apply when using AISI 4140 steel targets and the recommended power supply (-24 Vdc, 10 kW load).
Selection Guide & Purchasing Advice
Before ordering, verify your system requires a 5.0 meter probe with a miniature coaxial ClickLoc connector. The 146054-08-50-01-00 is a new, original factory-packed unit with a 12-month warranty from SpareTechPLC. Contact SpareTechPLC for current lifecycle status and availability. Ensure your Proximitor Sensor matches the 5 m cable length for proper operation.
