Bently Nevada 146054-08-05-01-00 3300 Ceramic Capped Proximity Probe

Product Introduction

When unplanned downtime threatens your rotating machinery, the Bently Nevada 146054-08-05-01-00 3300 Ceramic Capped Proximity Probe delivers precise shaft displacement measurements. This probe is part of the trusted 3300 series, designed for reliable vibration and position monitoring in harsh industrial environments. With a 3/8-24 UNF thread and ceramic tip, it withstands high temperatures and pressures while providing accurate data for predictive maintenance.

Technical Specifications Breakdown

Every specification of the 146054-08-05-01-00 is engineered for performance. The probe features a 0.8-inch overall case length (option -08) and a total cable length of 0.5 meters (1.6 feet). It uses a miniature coaxial ClickLoc connector with a connector protector and standard cable. The probe case thread is 3/8-24, with a maximum thread engagement of 0.563 inches. The nominal DC resistance from center conductor to outer conductor is 7.45 ± 0.50 ohms for the 0.5-meter probe. The linear range is 1.52 mm (60 mils), starting at approximately 0.25 mm from the target, with an incremental scale factor of 7.87 V/mm (200 mV/mil) for standard 5-meter or 9-meter systems. The probe tip is made of alumina ceramic (Al2O3), and the case is AISI 304 stainless steel. Operating and storage temperature range is -51°C to +177°C, and it is rated to seal 34 Bar (500 psi) nitrogen.

Industry Applications

This probe is ideal for monitoring radial vibration and thrust position in turbines, compressors, pumps, and other rotating equipment. In the oil and gas sector, it helps detect early signs of bearing wear or shaft misalignment, preventing catastrophic failures. Power generation plants use it for continuous vibration monitoring on steam and gas turbines, ensuring safe and efficient operation. The ceramic cap provides excellent resistance to harsh chemicals and high temperatures, making it suitable for chemical processing applications.

Installation & Setup Guidance

Proper installation is critical for accurate readings. Mount the probe with the 3/8-24 UNF thread into a suitable mounting hole, 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 connection to the extension cable. Verify that the total cable length (0.5 meters for this variant) matches your system requirements. For optimal performance, calibrate the system using an AISI 4140 steel target as specified.

Maintenance & Reliability

The 3300 Ceramic Capped Probe requires minimal maintenance due to its robust construction. Periodically inspect the probe cable and connector for damage, especially in high-vibration environments. The ceramic tip resists wear and contamination, but ensure the target surface remains clean and free of debris. The probe is rated for operation up to +177°C and 34 Bar pressure, making it reliable in demanding conditions. Regular verification of the system's linear range and scale factor helps maintain measurement accuracy.

Selection Guide & Purchasing Advice

When selecting the 146054-08-05-01-00, verify that the overall case length (0.8 in), total cable length (0.5 m), and connector type (miniature coaxial ClickLoc) match your application requirements.
