Bently Nevada 146054-08-05-00-05 3300 Ceramic Capped Proximity Probe

Product Introduction

When critical rotating machinery requires precise vibration monitoring, the Bently Nevada 146054-08-05-00-05 3300 Ceramic Capped Proximity Probe delivers reliable performance. This probe is part of the trusted 3300 series, designed for industrial applications where accuracy and durability are paramount. With a ceramic tip and stainless steel case, it withstands harsh environments while providing consistent measurements.

Technical Specifications

The 146054-08-05-00-05 features a 0.8-inch overall case length and a total length of 0.5 meters (1.6 feet). It uses a 3/8-24 UNF thread for secure mounting and comes without a connector (option 00). The probe is approved for hazardous locations with CSA, ATEX, and IECEx certifications (option -05). Available probe lengths include 0.5, 1, 2, 5, or 9 meters, ensuring flexibility for various installations.

The probe operates within a temperature range of -51°C to +177°C and is rated to seal 34 Bar (500 psi) nitrogen. Its nominal DC resistance is 7.45 ± 0.50 ohms for the 0.5-meter length, measured from center conductor to outer conductor.

Industry Applications

This proximity probe is ideal for monitoring vibration and position in turbines, compressors, pumps, and motors. In petrochemical plants, the ATEX and IECEx approvals allow safe use in explosive atmospheres. Maintenance engineers rely on its ceramic tip for long-term stability in high-temperature environments, reducing unplanned downtime.

Installation Guidance

When installing the 146054-08-05-00-05, ensure the probe case thread engages properly with the mounting hole. The maximum thread engagement length is 0.563 inches. Use the specified torque to avoid damaging the ceramic tip. For optimal performance, calibrate the system with an AISI 4140 steel target and verify the linear range from 0.25 to 1.78 mm (10 to 70 mils).

Maintenance & Reliability

Regular inspection of the probe cable and connector is recommended. The FEP-insulated coaxial cable resists chemicals and high temperatures. Check for physical damage or wear, especially in high-vibration areas. Following manufacturer guidelines ensures long service life and accurate readings.

Selection Guide & Purchasing Advice

Before ordering, verify the total length and connector type match your system requirements. The 146054-08-05-00-05 is supplied as new and original in factory packing with a 12-month warranty. For complete technical specifications, contact BluePLC Industrial.
