Bently Nevada 146054-08-10-00-05 3300 Ceramic Capped Proximity Probe

Introduction

When a turbine shaft begins to exhibit subsynchronous vibration, the cause may be oil whirl or rub. The Bently Nevada 146054-08-10-00-05 3300 ceramic capped proximity probe provides the precise, non-contact measurement needed to diagnose such issues. This 3/8-24 UNF thread probe, without armor, is designed for reliable displacement and vibration monitoring in critical rotating machinery.

Technical Specifications

The 146054-08-10-00-05 is part of the 3300 Ceramic Capped Proximity Probes series from Bently Nevada. Key specifications include:

Overall Case Length Option: -08 = 0.8 in (maximum thread engagement 0.563 in)

Total Length Option: -10 = 1.0 meter (3.3 feet)

Connector and Cable-Type Option: 00 = No connector

Agency Approval Option: -05 = CSA, ATEX, IECEx

Probe case thread: 3/8-24

Available probe lengths: 0.5, 1, 2, 5, or 9 meters

These parameters ensure compatibility with standard 3300 XL system components for accurate, repeatable measurements.

Industry Applications

The 146054-08-10-00-05 is ideal for monitoring radial vibration and axial position in steam turbines, compressors, and large pumps. Its ceramic tip provides excellent wear resistance in high-temperature environments up to +177°C. The CSA, ATEX, and IECEx approvals make it suitable for hazardous area installations in oil and gas, petrochemical, and power generation facilities.

Installation & Setup Guidance

Proper installation begins with verifying the thread engagement: the 3/8-24 UNF thread allows a maximum engagement of 0.563 in. The probe should be mounted securely using the specified case length of 0.8 in. Ensure the target surface is clean and made of AISI 4140 steel for optimal linear range performance. The system linear range is 1.52 mm (60 mils), starting approximately 0.25 mm from the target.

Maintenance & Reliability

Routine inspection of the probe cable and connector is recommended. The probe is rated to seal 34 Bar (500 psi) nitrogen. For high-pressure applications, contact the custom design department. The operating and storage temperature range is -51°C to +177°C, ensuring reliable performance in harsh conditions. The 12-month factory warranty provides peace of mind.

Selection Guide & Purchasing Advice

Before ordering, confirm the total length option (1.0 meter for this variant) and the connector type (none). The 146054-08-10-00-05 includes agency approvals for CSA, ATEX, and IECEx.
