Product Overview
When a turbine or compressor goes down, every hour of downtime hurts. The Bently Nevada 146054-08-05-01-00 is a 3300 ceramic capped proximity probe built to keep your vibration monitoring system online. This probe uses a 3/8-24 UNF thread and comes without armor. It ships new and original in factory packing, ready for immediate installation.
Bently Nevada designed the 3300 series for accurate, repeatable displacement measurements. The ceramic tip resists wear in harsh oil and gas environments. With a 0.5 meter cable, this probe fits tight machine housings where longer runs would be impractical.
Key Specifications That Matter
The 146054-08-05-01-00 delivers a linear range of 1.52 mm (60 mils), starting at approximately 0.25 mm (10 mils) from the target. That range translates to -4 to -16 Vdc output, giving your monitoring system clear, usable data.
The incremental scale factor (ISF) is 7.87 V/mm (200 mV/mil) ±6.5% over the linear range from 0°C to +45°C. This accuracy helps you detect small changes in shaft position before they become costly failures.
The probe tip uses alumina ceramic (Al2O3), while the case is AISI 304 stainless steel. This combination handles temperatures from -51°C to +177°C (-60°F to +351°F). The probe also seals against 34 Bar (500 psi) nitrogen pressure, so it stands up to demanding process conditions.
The standard cable is 75 Ω coaxial with fluoroethylene propylene (FEP) insulation. The miniature coaxial ClickLoc connector includes a protector for added durability during installation.
Where This Probe Fits
Oil and gas operators rely on the 146054-08-05-01-00 for steam turbines, centrifugal compressors, and large motors. In a refinery, for example, this probe mounts on a compressor bearing housing to measure shaft vibration. The 0.5 meter cable reaches the Proximitor sensor without excess slack.
In power generation, the ceramic tip resists wear from continuous operation. The stainless steel case handles wash-down and humid conditions. Because the probe works with 3300 XL system components, it integrates into existing Bently Nevada monitoring racks.
For industrial automation applications, this probe provides reliable position feedback on rotating equipment. The 3/8-24 UNF thread matches standard mounting adapters, so retrofits go quickly.
Installation and Setup
Mount the probe using the 3/8-24 UNF thread. Maximum thread engagement is 0.563 inches. Ensure the target is AISI 4140 steel for rated accuracy. The linear range begins at approximately 0.25 mm (10 mils) from the target, so set the gap within that window.
Route the 75 Ω coaxial cable away from high-voltage wiring to avoid signal interference. The ClickLoc connector protector keeps the connection secure in vibrating environments. Verify the probe’s DC resistance from center conductor to outer conductor: 7.45 ± 0.50 ohms for the 0.5 meter length.
Maintenance and Reliability
Inspect the probe tip periodically for ceramic chipping or buildup. Clean the threaded area during scheduled outages to prevent seizing. Check cable insulation for cracks, especially near the connector. The FEP insulation resists chemicals and moisture, but physical damage still requires replacement.
Because this probe operates from -51°C to +177°C, it suits both hot and cold climates. For higher-pressure applications, contact Bently Nevada’s custom design department about pressure seal testing.
