Product Overview
When rotating machinery experiences unplanned shutdowns, the root cause often traces back to undetected vibration or position changes. The Bently Nevada 146054-08-05-00-05 3300 Ceramic Capped Proximity Probe provides reliable, non-contact measurement to help prevent such failures. This probe is part of the 3300 series, designed for use with compatible Proximitor sensors and extension cables in turbine, compressor, and pump monitoring systems. The Option: 00=No connector configuration offers flexibility for custom cabling setups.
Technical Specifications Breakdown
The 146054-08-05-00-05 delivers a linear range of 1.52 mm (60 mils), beginning at approximately 0.25 mm (10 mils) from the target. This range suits close-gap monitoring in high-speed machinery. The Incremental Scale Factor (ISF) is 7.87 V/mm (200 mV/mil) ±6.5% for standard 5-meter or 9-meter systems, ensuring consistent output over temperature from 0°C to +45°C. The probe case is AISI 304 stainless steel, and the tip is alumina ceramic (Al2O3) for durability in harsh environments. Operating temperature spans -51°C to +177°C, and the probe is rated to seal 34 Bar (500 psi) nitrogen.
Industry Applications
In steam turbine vibration monitoring, the 146054-08-05-00-05 provides precise shaft relative vibration data. Its ceramic tip resists wear from high-speed rotation, and the 0.5-meter cable length suits installations where the Proximitor is mounted nearby. For centrifugal compressors in oil and gas facilities, the probe's ATEX and IECEx approvals (Option -05) allow use in hazardous areas. The 3/8-24 UNF thread simplifies mounting into standard probe holders.
Installation & Setup Guidance
Mount the probe using the 3/8-24 UNF thread, ensuring the maximum thread engagement of 0.563 inches is not exceeded. The probe tip should face an AISI 4140 steel target for calibration consistency. Connect the 75 Ω coaxial FEP-insulated cable to a compatible extension cable or directly to a Proximitor sensor (if using a custom connector, not provided). Verify the total system length matches the 0.5-meter probe specification. For optimal performance, operate within -51°C to +177°C and avoid exceeding 34 Bar pressure.
Maintenance & Reliability
The ceramic tip and stainless steel case resist corrosion and mechanical wear. Periodically inspect the probe cable for cuts or abrasion, especially near connection points. Clean the probe tip with a soft, dry cloth if debris accumulates. The probe's wide temperature range and pressure rating reduce the risk of failure in demanding environments, supporting long service intervals.
Selection Guide & Purchasing Advice
Before ordering, confirm your system requirements: the 146054-08-05-00-05 has a 0.5-meter total length and no connector. If you need a different cable length or connector type, select the appropriate option code. Verify that your Proximitor and extension cable are compatible with 3300 series probes.
