Product Overview
The Bently Nevada 146054-08-10-00-05 is a 3300 Ceramic Capped Proximity Probe designed for precise vibration and position monitoring in critical rotating machinery. This Industrial Automation Module delivers reliable performance in harsh environments, featuring an alumina ceramic tip and AISI 304 stainless steel case for durability. With a 1.0-meter total length and 3/8-24 UNF thread, this probe integrates seamlessly into existing 3300 XL systems.
Each unit ships new and in original factory packing, backed by a 12-month factory warranty. The 146054-08-10-00-05 configuration includes a 0.8-inch overall case length, no connector option, and agency approvals for CSA, ATEX, and IECEx, making it suitable for hazardous area installations.
Technical Specifications
The 146054-08-10-00-05 offers a linear range of 1.52 mm (60 mils), starting at approximately 0.25 mm from the target and extending to 1.78 mm. The incremental scale factor (ISF) for standard 5-meter or 9-meter systems is 7.87 V/mm (200 mV/mil) with ±6.5% interchangeability error, measured over the full linear range from 0°C to +45°C. Probe nominal DC resistance is 7.59 ± 0.50 ohms, measured from center conductor to outer conductor for the 1.0-meter probe length.

Industry Applications
The 146054-08-10-00-05 excels in turbomachinery monitoring, including steam turbines, gas turbines, compressors, and pumps. Its ceramic cap provides wear resistance in high-speed applications, while the ATEX/IECEx approvals allow installation in explosive atmospheres. For example, in a refinery compressor train, this probe delivers accurate shaft displacement readings, helping operators detect thrust bearing wear early and avoid unplanned outages.
Additionally, the probe's 1.0-meter cable length suits compact installations where space is limited, and its stainless steel case resists corrosion in offshore or chemical processing environments.
Installation & Setup Guidance
When installing the 146054-08-10-00-05, ensure the target surface is clean and free of debris. Mount the probe with the 3/8-24 UNF thread, engaging at least 0.563 inches of thread for a secure fit. Calibrate the system using the provided ISF value of 7.87 V/mm, and verify the linear range by positioning the probe between 0.25 mm and 1.78 mm from the target. For hazardous areas, follow local regulations for EPL Ga, Gc, or Dc as per the temperature schedule.
Maintenance & Reliability
The ceramic tip and stainless steel construction minimize wear, extending service life. Periodically inspect the probe cable for damage, especially in high-vibration areas. The operating temperature range of -51°C to +177°C allows use in extreme environments, but avoid exceeding the pressure rating of 34 Bar. Regular calibration checks, as recommended by Bently Nevada, ensure measurement accuracy and reduce downtime.
Selection Guide & Purchasing Advice
Before purchasing the 146054-08-10-00-05, verify your system's compatibility with the 3300 XL series and confirm the required cable length and connector type. The -05 agency approval covers CSA, ATEX, and IECEx, so check your site's certification needs. PLC Source PRO offers this new, factory-packed unit with a 12-month warranty, ensuring you receive a genuine Bently Nevada product ready for immediate installation.
