Product Overview
When precise shaft vibration and position monitoring is critical for rotating machinery protection, the Bently Nevada 146054-08-90-01-05 delivers reliable performance. This 3300 Ceramic Capped Proximity Probe is designed for use with 3300 XL Proximitor systems, providing accurate displacement measurements in harsh industrial environments.
Technical Specifications Breakdown
The 146054-08-90-01-05 features a 3/8-24 UNF thread probe case with a maximum thread engagement length of 0.563 inches. The probe tip is made of alumina ceramic (Al2O3), offering excellent wear resistance. The probe case is constructed from AISI 304 stainless steel for durability.
Key performance parameters include 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) for a 9-meter system is 7.87 V/mm (200 mV/mil) with ±6.5% interchangeability error over the full linear range.
Industry Applications
This proximity probe is ideal for monitoring radial vibration and axial position in turbines, compressors, pumps, and other rotating machinery. The ceramic tip withstands high temperatures up to +177°C (-60°F to +351°F operating and storage temperature), making it suitable for steam turbine and gas compressor applications.
Installation & Setup Guidance
When installing the 146054-08-90-01-05, ensure the probe tip is properly positioned within the linear range of 0.25 to 1.78 mm from the target surface. The miniature coaxial ClickLoc connector with connector protector simplifies cable attachment. Verify the cable length of 9.0 meters (29.5 feet) matches system requirements before installation.
Maintenance & Reliability
Regular inspection of the probe cable and connector is recommended to maintain signal integrity. The probe is rated to seal 34 Bar (500 psi) nitrogen, suitable for many pressurized applications. For higher-pressure environments, contact the custom design department for modifications.
Compatibility & Integration
This probe is part of the 3300 XL system and works with compatible Proximitor sensors and extension cables. Performance specifications apply when used with 3300 XL components and an AISI 4140 steel target. The system accuracy is verified over a temperature range of +18°C to +27°C (+64°F to +80°F) with a -24 Vdc power supply and 10 kΩ load.
Selection Guide & Purchasing Advice
Before ordering the 146054-08-90-01-05, verify the overall case length (0.8 inches), total probe length (9.0 meters), and agency approval option (-0 5 = CSA, ATEX, IECEx). This model includes the miniature coaxial ClickLoc connector with standard cable. SpareTechPLC offers this probe new and in original factory packing with a 12-month warranty.
