Bently Nevada 146054-08-10-01-00 3300 Ceramic Capped Proximity Probe

Product Overview

When monitoring critical rotating machinery, accurate and reliable displacement measurement is essential. The Bently Nevada 146054-08-10-01-00, part of the 3300 Ceramic Capped Proximity Probe series, delivers precise performance for demanding industrial applications. This probe features a 3/8-24 UNF thread, a 0.8 inch overall case length, and a 1.0 meter total length, making it suitable for tight installations where space is limited.

Technical Specifications Breakdown

Understanding the key specifications helps you evaluate if this probe meets your system requirements. The 146054-08-10-01-00 offers a linear range of 1.52 mm (60 mils), starting at approximately 0.25 mm (10 mils) from the target. This range corresponds to an output of approximately -4 to -16 Vdc. The incremental scale factor (ISF) for a standard 5-meter or 9-meter system is 7.87 V/mm (200 mV/mil) with ±6.5% interchangeability error over the full linear range from 0°C to +45°C.

The probe tip is made of alumina ceramic (Al2O3), providing wear resistance and thermal stability. The probe case is constructed from AISI 304 stainless steel, ensuring durability in harsh environments. The nominal DC resistance from the center conductor to the outer conductor is 7.59 ± 0.50 ohms for a 1.0 meter probe length.

Industry Applications

This proximity probe is commonly used in turbomachinery monitoring, including steam turbines, gas turbines, compressors, and pumps. Its ceramic tip and stainless steel case allow it to withstand high temperatures up to +177°C and pressures up to 34 Bar (500 psi) when sealed with nitrogen. The -51°C to +177°C operating temperature range makes it suitable for both cold climate and high-heat applications.

Installation & Setup Guidance

Proper installation is critical for accurate measurements. The probe thread engagement maximum length is 0.563 inches. When mounting, ensure the probe tip is positioned within the linear range (0.25 to 1.78 mm from the target). Use the miniature coaxial ClickLoc connector with connector protector for secure cable attachment. The standard cable is 75 ohm coaxial, fluoroethylene propylene (FEP) insulated, available in 0.5, 1, 2, 5, or 9 meter lengths. Verify that the system includes a -24 Vdc power supply and a 10 kΩ load for optimal performance.

Maintenance & Reliability

To maintain reliable operation, periodically inspect the probe cable and connector for damage. The ceramic tip is resistant to wear but should be checked for cracks or contamination. The probe is rated to seal up to 34 Bar (500 psi) nitrogen; for higher-pressure applications, contact the custom design department. Regular calibration verification against an AISI 4140 steel target ensures system accuracy and interchangeability.

Selection Guide & Purchasing Advice

When selecting the 146054-08-10-01-00, confirm that your system requires a 0.8 inch case length and 1.0 meter total length. The Option: 01= includes the miniature coaxial ClickLoc connector with protector and standard cable. Agency approval option -00 means no special certification is required.
