Solving Vibration Monitoring Challenges in Rotating Machinery
When unexpected machine downtime disrupts production, the root cause often lies in undetected shaft vibration. The Bently Nevada 146055-10-02-00 3300 Ceramic Capped Reverse Mount Probe provides the precise, reliable measurement needed to prevent such failures. This probe is engineered for continuous monitoring of radial vibration and shaft position in critical rotating equipment like turbines, compressors, and pumps.
Product Overview
The 146055-10-02-00 is part of the Bently Nevada 3300 series, specifically a Ceramic Capped Reverse Mount Probe. It features a 1.0 meter (3.3 feet) total length with a Miniature ClickLoc coaxial connector and standard cable. The probe case uses 3/8-24 UNF threads, with a maximum thread engagement of 0.563 inches. The probe tip is made from alumina ceramic (Al2O3), and the case is AISI 304 stainless steel, ensuring durability in harsh industrial environments.
Key Technical Specifications
- Linear Range: 1.52 mm (60 mils), beginning at approximately 0.25 mm (10 mils) from the target.
- Incremental Scale Factor (ISF): 7.87 V/mm (200 mV/mil) ±6.5% for standard 5-meter or 9-meter systems, measured over the 60 mil linear range from 0°C to +45°C (+32°F to +113°F).
- Probe Nominal DC Resistance: 7.59 ± 0.50 ohms (from center conductor to outer conductor) for a 1.0 meter probe.
- Temperature Range: Operating and storage from -51°C to +177°C (-60°F to +351°F).
- Pressure Rating: Rated to seal 34 Bar (500 psi) nitrogen.
- Cable: 75 Ω coaxial, fluoroethylene propylene (FEP) insulated probe cable.
These specifications ensure accurate and repeatable measurements across a wide range of operating conditions.
Real-World Applications
In a petrochemical plant, a 146055-10-02-00 probe mounted on a large centrifugal compressor continuously monitors shaft vibration. The probe's 1.52 mm linear range and high sensitivity (7.87 V/mm) allow early detection of developing faults, such as unbalance or misalignment. This enables maintenance teams to schedule repairs during planned outages, avoiding costly unplanned shutdowns. The robust ceramic tip and stainless steel case withstand the high temperatures and pressures common in such environments.
Installation and Setup Guidance
For optimal performance, mount the probe with the 3/8-24 UNF thread into a suitable bracket or housing. Ensure the probe tip is positioned within the linear range (0.25 to 1.78 mm from the target). Use the Miniature ClickLoc connector to secure the standard coaxial cable. Verify the system includes a compatible Bently Nevada 3300 Proximitor Sensor and extension cable for full functionality. Calibrate the system with an AISI 4140 steel target as specified.
Maintenance and Reliability
The 146055-10-02-00 is designed for long-term reliability with minimal maintenance. Regularly inspect the probe cable and connector for damage. Ensure the probe tip remains clean and free from debris. The probe's operating temperature range of -51°C to +177°C allows use in extreme environments. Periodic verification of the system's scale factor and linearity using a calibration fixture is recommended to maintain measurement accuracy.
Compatibility and Integration
This probe is designed for use with Bently Nevada 3300 XL system components, including Proximitor Sensors and extension cables. It works with standard 5-meter or 9-meter system configurations. The 75 Ω coaxial cable ensures signal integrity over long distances. The probe is compatible with Bently Nevada monitoring systems that accept eddy-current proximity probe inputs.
Selection Guide and Purchasing Advice
When ordering the 146055-10-02-00, verify the total length option (-10 = 1.0 meter) and connector type (-0 2 = Miniature ClickLoc coaxial connector). Confirm the agency approval option (-00 = not required) meets your site requirements. SpareTechPLC offers this probe in new and original factory packaging with a 12-month warranty. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
