Product Overview
When machinery vibration threatens uptime in critical rotating equipment, the Bently Nevada 146055-50-02-00 provides reliable, precise measurement. This 3300 ceramic capped reverse mount probe is engineered for continuous monitoring in harsh industrial environments. With a 5.0-meter integral cable and Miniature ClickLoc coaxial connector, it integrates seamlessly into existing Bently Nevada systems.
Technical Specifications Breakdown
The 146055-50-02-00 offers a linear range of 1.52 mm (60 mils), starting at approximately 0.25 mm (10 mils) from the target. This range covers 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). The probe case thread is 3/8-24 UNF, with a maximum thread engagement of 0.563 inches. The probe tip material is alumina ceramic (Al2O3), and the case is AISI 304 stainless steel, ensuring durability in demanding conditions.
Industry Applications
This probe is ideal for vibration monitoring on turbines, compressors, pumps, and motors. In a typical steam turbine application, the 146055-50-02-00 mounts in a reverse orientation to measure shaft radial vibration. Its ceramic tip resists wear and contamination, maintaining accuracy over long service intervals. For centrifugal compressors, the 5.0-meter cable length suits installations where the proximity probe is located several meters from the proximitor sensor.
Installation & Setup Guidance
When installing the 146055-50-02-00, ensure the probe tip is clean and the target surface is AISI 4140 steel for optimal performance. The probe is rated to seal 34 Bar (500 psi) nitrogen, suitable for pressurized environments. For 5-meter probes, use only the matching 5-meter Proximitor Sensor to maintain system accuracy. Verify the thread engagement does not exceed 0.563 inches to avoid damage. The cable connector is a Miniature ClickLoc coaxial type, requiring no special tools for connection.
Maintenance & Reliability
Regular inspection of the probe cable and connector is recommended to prevent signal degradation. The probe operates and stores from -51°C to +177°C (-60°F to +351°F), covering most industrial temperature ranges. The ceramic tip and stainless steel case resist corrosion and physical damage. For long-term reliability, verify the target material and gap settings during scheduled maintenance. The 12-month factory warranty from SpareTechPLC ensures peace of mind.
Compatibility & Integration
The 146055-50-02-00 is part of the 3300 XL system family and is designed for use with Bently Nevada Proximitor Sensors and extension cables. It integrates with monitoring systems that accept standard –4 to –16 Vdc input from proximity probes. The 75 Ω coaxial cable ensures signal integrity over the 5.0-meter length. For new installations, pair this probe with a compatible 3300 XL Proximitor Sensor for optimal performance.
Buying Guide & Selection Advice
Before purchasing the 146055-50-02-00, confirm the total length option (5.0 meters) and connector type (Miniature ClickLoc coaxial) match your system requirements. Verify the thread size (3/8-24 UNF) fits your mounting hardware. SpareTechPLC stocks this probe in new, factory-sealed condition with full warranty.
