Product Overview
When monitoring critical rotating machinery, the Bently Nevada 146054-08-90-00-05 provides reliable vibration and position sensing. This 3300 Ceramic Capped Proximity Probe is designed for demanding industrial environments. It features a 9.0-meter (29.5 feet) total length and a 3/8-24 UNF thread for secure mounting. The probe case is made of AISI 304 stainless steel, and the probe tip uses alumina ceramic (Al2O3) for durability. Agency approvals include CSA, ATEX, and IECEx, making it suitable for hazardous area installations.
Technical Specifications Breakdown
The 146054-08-90-00-05 offers 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% for a 9-meter system over 0°C to +45°C. The probe operates from -51°C to +177°C and is rated to seal 34 Bar (500 psi) nitrogen. The nominal DC resistance from center conductor to outer conductor is 9.87 ± 0.90 ohms for the 9.0-meter probe.
Industry Applications
This probe is ideal for vibration monitoring on turbines, compressors, pumps, and other rotating equipment. The ceramic cap provides wear resistance in high-speed applications. The 9.0-meter cable length allows flexible installation away from the machine. With ATEX and IECEx certification, it can be used in potentially explosive atmospheres.
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 system accuracy. The linear range begins at 0.25 mm from the target; adjust the gap accordingly. Use the standard 75 ohm coaxial FEP insulated cable. For best performance, operate within +18°C to +27°C for the full system.
Maintenance & Reliability
Inspect the probe cable and tip periodically for wear or damage. The alumina ceramic tip resists abrasion, but verify the pressure seal if used in high-pressure environments. The stainless steel case withstands corrosion. Regular calibration checks against the specified ISF ensure measurement accuracy.
Buying Guide
When ordering the 146054-08-90-00-05, confirm the overall case length (0.8 in) and total length (9.0 meters) match your requirements. This probe comes without a connector (Option 0 0=). SpareTechPLC supplies this item new and in original factory packing with a 12-month warranty. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
