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

Product Introduction

When precise vibration and position monitoring is critical for rotating machinery, the Bently Nevada 146054-08-05-00-05 3300 Ceramic Capped Proximity Probe delivers reliable performance. This probe is part of the 3300 series, designed for non-contact measurement of shaft displacement and vibration in industrial turbomachinery, compressors, and pumps. With a 3/8-24 UNF thread and no armor, it offers a robust solution for demanding environments.

Technical Specifications Breakdown

The 146054-08-05-00-05 features a 0.8-inch overall case length (option -08) and a total probe length of 0.5 meter (1.6 feet). The probe case thread is 3/8-24, ensuring secure mounting. It comes without a connector (option 00) and includes agency approvals for CSA, ATEX, and IECEx (option -05), making it suitable for hazardous area installations. The probe tip is made of alumina ceramic (Al2O3), and the case is AISI 304 stainless steel. It operates over a temperature range of -51°C to +177°C and is rated to seal 34 Bar (500 psi) nitrogen.

Industry Applications

This proximity probe is ideal for monitoring radial vibration and axial position in steam turbines, gas turbines, and centrifugal compressors. In a typical petrochemical plant, the 146054-08-05-00-05 can be installed on a compressor train to detect shaft misalignment or bearing wear early, preventing costly unplanned downtime. Its ceramic cap provides excellent resistance to harsh process conditions, extending service life in high-temperature or corrosive environments.

Installation & Setup Guidance

When installing the 146054-08-05-00-05, ensure the probe tip is positioned within the linear range of 0.25 to 1.78 mm from the target surface. The probe case thread should be engaged to a maximum depth of 0.563 inches. Use the provided 75 Ω coaxial FEP-insulated cable and avoid sharp bends to maintain signal integrity. For systems requiring higher pressure ratings, contact Bently Nevada for custom modifications.

Maintenance & Reliability

Regular inspection of the probe cable and connector is recommended to ensure consistent performance. The ceramic tip is durable but should be checked for cracks or contamination during routine outages. Operating within the specified temperature range (-51°C to +177°C) and pressure limits (34 Bar) will maximize reliability. For safety-rated installations, always follow the manufacturer's guidelines for periodic testing.

Selection Guide & Purchasing Advice

Before ordering the 146054-08-05-00-05, verify the required overall case length and total probe length for your application. This model is configured with a 0.8-inch case and 0.5-meter cable without a connector. If you need a different length or connector type, refer to the ordering code structure.
