Product Overview
When vibration monitoring in harsh industrial environments demands precision and durability, the Bently Nevada 146054-08-05-02-05 delivers reliable performance. This 3300 Ceramic Capped Proximity Probe is designed for non-contact displacement measurements of rotating machinery. Its alumina ceramic tip and AISI 304 stainless steel case provide excellent resistance to wear and corrosion. The probe uses a 3/8-24 UNF thread and comes without armor, making it suitable for standard mounting configurations.
Technical Specifications Breakdown
The 146054-08-05-02-05 offers a linear range of 1.52 mm (60 mils), starting at approximately 0.25 mm (10 mils) from the target. This range corresponds to an output of approximately -4 to -16 Vdc. The incremental scale factor (ISF) is 7.87 V/mm (200 mV/mil) with ±6.5% interchangeability error when measured over the full linear range. The probe operates with a nominal DC resistance of 7.45 ± 0.50 ohms from center conductor to outer conductor. Its temperature range spans -51°C to +177°C for both operating and storage, and it is rated to seal 34 Bar (500 psi) nitrogen.
Industry Applications
This proximity probe excels in monitoring shaft vibration and position in turbines, compressors, and pumps. The ceramic tip withstands high temperatures and pressures common in steam turbines and gas compressors. The 0.5-meter cable length suits installations where the sensor is close to the machine casing, reducing signal loss. The CSA, ATEX, and IECEx approvals allow use in hazardous areas requiring explosion-proof equipment.
Installation & Setup Guidance
Mount the probe using the 3/8-24 UNF thread with a maximum thread engagement of 0.563 inches. Ensure the target is AISI 4140 steel for optimal system accuracy. The system includes a Proximitor Sensor and extension cable; performance specifications apply when using solely 3300 XL components. Calibrate the system between +18°C and +27°C with a -24 Vdc power supply and a 10 kW load for best results.
Maintenance & Reliability
The ceramic probe tip and stainless steel case minimize maintenance needs. Inspect the cable and connector periodically for damage. The probe is rated for operation from -51°C to +177°C, so verify ambient conditions stay within this range. The pressure seal is rated to 34 Bar (500 psi) nitrogen; contact the manufacturer for higher-pressure applications.
Selection Guide & Purchasing Advice
Before ordering, confirm the overall case length (-08 = 0.8 in), total length (-05 = 0.5 meter), connector type (miniature coaxial ClickLoc with connector protector), and agency approval (-02 = CSA, ATEX, IECEx). SpareTechPLC supplies this probe new and in original factory packing with a 12-month warranty. Verify current lifecycle status and availability with SpareTechPLC before ordering.
