What Is the 146054-08-10-01-00 Probe?
How do you keep a steam turbine or compressor running when vibration data suddenly looks wrong? The 146054-08-10-01-00 is a Bently Nevada 3300 ceramic capped proximity probe built to answer that question. It measures shaft displacement and vibration in rotating machinery, and its alumina ceramic tip resists wear in harsh oil, gas, and power environments.
This probe uses a 3/8-24 UNF case thread without armor, a 0.8 in case length, and a 1.0 meter total length. The miniature coaxial ClickLoc connector includes a protector and standard cable. The unit ships new and original in factory packing.
Key Parameters That Matter
Linear Range and Scale Factor
The probe offers a 1.52 mm (60 mils) linear range, starting about 0.25 mm (10 mils) from the target and running to 1.78 mm (10 to 70 mils), roughly -4 to -16 Vdc. The incremental scale factor is 7.87 V/mm (200 mV/mil) with ±6.5% interchangeability error over the linear range from 0°C to +45°C. In practice, that means stable, repeatable displacement readings across the measuring window.
Materials and Environmental Limits
The tip is alumina ceramic (Al2O3); the case is AISI 304 stainless steel. The probe operates and stores from -51°C to +177°C and seals to 34 Bar (500 psi) nitrogen. For high-temperature zones, the temperature schedule supports T2 classification up to +177°C.
Electrical and Cable Details
The nominal DC resistance from center conductor to outer conductor is 7.59 ± 0.50 ohms at 1.0 m. The standard cable is FEP insulated, available in 0.5, 1, 2, 5, or 9 meter lengths.
Where This Probe Fits
Oil and gas operators use the 146054-08-10-01-00 on steam turbines, centrifugal compressors, and pumps where shaft movement must stay within tolerance. The ceramic cap suits dirty or abrasive service, and the 34 Bar pressure seal handles high-pressure casings. Power plants also deploy it for long-term vibration monitoring on critical drive trains.
Installation and Maintenance Pointers
Mount the probe through a 3/8-24 threaded hole with at least 0.563 in of thread engagement. Keep the target within the linear range and confirm the gap voltage sits between -4 and -16 Vdc. Inspect the ceramic tip periodically for chips or buildup, and check the ClickLoc connector for tightness. Follow the manufacturer’s safety manual for all work on pressurized machines.
Compatibility and Selection Notes
This probe belongs to the 3300 5 mm system family. Performance specs apply when the system uses 3300 XL components and an AISI 4140 steel target. If your target material differs, system accuracy and interchangeability specs no longer apply. Before ordering, confirm your Proximitor sensor, extension cable, and target material match.
