Product Overview
When unplanned downtime threatens your rotating machinery, the Bently Nevada 146054-08-50-01-05 3300 Ceramic Capped Proximity Probe delivers reliable, high-precision measurements. This probe is part of the trusted 3300 series, engineered for continuous vibration and position monitoring in harsh industrial environments. Its alumina ceramic tip and AISI 304 stainless steel case ensure durability and consistent performance.
Technical Specifications Breakdown
The 146054-08-50-01-05 offers a linear range of 1.52 mm (60 mils), starting at approximately 0.25 mm (10 mils) from the target. This provides a usable span from 0.25 to 1.78 mm (10 to 70 mils), corresponding to approximately -4 to -16 Vdc output. The incremental scale factor (ISF) is 7.87 V/mm (200 mV/mil) with ±6.5% interchangeability error over the full linear range from 0°C to +45°C (+32°F to +113°F). Key specifications include:
- Probe Length: 5.0 meters (16.4 feet)
- Connector: Miniature coaxial ClickLoc with connector protector
- Thread: 3/8-24 UNF, maximum thread engagement 0.563 in
- DC Resistance: 8.73 ± 0.70 ohms (center to outer conductor)
- Temperature Range: -51°C to +177°C (-60°F to +351°F)
- Pressure Rating: 34 Bar (500 psi) nitrogen
- Agency Approvals: CSA, ATEX, IECEx
Industry Applications
This probe excels in monitoring critical rotating assets such as steam turbines, centrifugal compressors, and large pumps. Its ceramic cap provides superior resistance to wear and contamination, making it ideal for environments with high-speed shafts or particulate matter. The 5.0-meter cable length is specifically designed for use with the 5 m Proximitor Sensor, ensuring system compatibility and accurate readings.
Installation & Setup Guidance
Proper installation is crucial for accurate measurements. Mount the probe with the 3/8-24 UNF thread into a suitable bracket or housing, ensuring the tip is positioned within the linear range (0.25 to 1.78 mm from the target). Use the miniature coaxial ClickLoc connector for a secure, vibration-resistant connection. Verify the DC resistance (8.73 ± 0.70 ohms) to confirm cable integrity before commissioning.
Maintenance & Reliability
The 3300 series probes are built for long service life. The alumina ceramic tip resists abrasion, and the stainless steel case withstands corrosive environments. Regular inspection of the cable and connector for damage is recommended. The probe operates reliably across a wide temperature range (-51°C to +177°C), reducing the need for frequent replacements and lowering total cost of ownership.
Compatibility & Integration
This probe is part of a 3300 5 mm system that includes the Proximitor Sensor and extension cable. For optimal performance, use only with Bently Nevada 3300 XL components. The system is calibrated using an AISI 4140 steel target; using other target materials may affect accuracy. The probe's output is compatible with standard vibration monitoring systems.
Selection Guide & Purchasing Advice
Before ordering, verify the total cable length (5.0 meters) and connector type (miniature coaxial ClickLoc) match your system requirements. The 146054-08-50-01-05 includes agency approvals for hazardous areas (CSA, ATEX, IECEx). SpareTechPLC offers this probe as a new, factory-sealed unit with a 12-month warranty.
