Product Overview
When machinery vibration threatens production uptime, the Bently Nevada 146054-08-05-01-00 provides reliable, high-accuracy proximity sensing. This 3300 Ceramic Capped Probe is engineered for continuous monitoring in demanding industrial environments, offering a linear measurement range of 1.52 mm (60 mils) with an incremental scale factor of 7.87 V/mm (200 mV/mil). Whether you are monitoring turbine shaft vibration or compressor thrust position, this probe delivers consistent performance.
Technical Specifications
The 146054-08-05-01-00 features a 3/8-24 UNF threaded probe case made from AISI 304 stainless steel, ensuring durability in harsh conditions. The probe tip is constructed from alumina ceramic (Al2O3), providing excellent wear resistance. With a total length of 0.5 meters (1.6 feet) and an overall case length of 0.8 inches, this probe fits tight installations. The nominal DC resistance from center conductor to outer conductor is 7.45 ± 0.50 ohms. The operating and storage temperature range spans from -51°C to +177°C (-60°F to +351°F), and the probe is rated to seal 34 Bar (500 psi) nitrogen.
Industry Applications
In steam turbine monitoring, the 146054-08-05-01-00 measures shaft radial vibration and axial position with high repeatability. Its ceramic tip resists wear from high-speed rotation, reducing maintenance intervals. For centrifugal compressors in oil and gas applications, the probe’s 0.5 meter cable length simplifies routing to the proximitor sensor. The linear range from 0.25 mm to 1.78 mm (10 to 70 mils) covers typical clearance gaps, making it suitable for both alarm and trip functions.
Installation & Setup Guidance
Mount the probe using the 3/8-24 UNF thread, ensuring the maximum thread engagement of 0.563 inches is not exceeded. Use the miniature coaxial ClickLoc connector with connector protector for secure cable attachment. Calibrate the system with an AISI 4140 steel target for optimal accuracy. The system accuracy specifications apply only when using 3300 XL components together.
Maintenance & Reliability
Regularly inspect the probe cable and connector for damage, especially in high-vibration areas. The stainless steel case resists corrosion, but verify the pressure seal integrity if the probe is installed in pressurized environments. The wide temperature range ensures reliable operation in extreme conditions, reducing unplanned downtime.
Selection Guide & Purchasing Advice
Before ordering the 146054-08-05-01-00, confirm your system requires a 0.5 meter cable length and a 3/8-24 thread. Verify compatibility with your existing Bently Nevada 3300 XL proximitor and extension cable. SpareTechPLC supplies this probe as new and original in factory packaging with a 12-month warranty. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
