Product Overview
When machinery vibration threatens uptime and safety, the Bently Nevada 146055-10-02-05 delivers precise, reliable measurements. This 3300 Ceramic Capped Reverse Mount Probe is engineered for demanding industrial environments where accurate proximity sensing is critical. With a 1.0 meter (3.3 feet) total length and 3/8-24 UNF threads, it integrates seamlessly into existing monitoring systems.
Technical Specifications Breakdown
The 146055-10-02-05 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) ±6.5% including interchangeability error, measured over the 60 mil linear range from 0°C to +45°C (+32°F to +113°F).
Probe Resistance and Mechanical Design
The nominal DC resistance from center conductor to outer conductor is 7.59 ± 0.50 ohms for the 1.0 meter probe. The probe tip is made of alumina ceramic (Al2O3), while the probe case uses AISI 304 stainless steel. Maximum thread engagement length is 0.563 inches. The standard cable is 75 Ω coaxial, fluoroethylene propylene (FEP) insulated, available in 0.5, 1, 2, 5, or 9 meter lengths.
Environmental Ratings
Operating and storage temperature ranges from -51°C to +177°C (-60°F to +351°F). The probe is rated to seal 34 Bar (500 psi) nitrogen, with modifications available for higher-pressure applications. A detailed temperature schedule is provided for various EPL classifications (Ga, Gc, Dc).
Industry Applications
This probe excels in rotating machinery monitoring—turbines, compressors, pumps, and motors. Its ceramic tip resists wear and contamination, making it suitable for harsh environments like oil and gas, power generation, and petrochemical plants. The reverse mount design simplifies installation in tight spaces.
Installation & Setup Guidance
Mount the probe with proper clearance to the target surface. Ensure the target is AISI 4140 steel for system accuracy and interchangeability specifications. Use the Miniature ClickLoc coaxial connector for secure cable attachment. Calibrate the system with a -24 Vdc power supply and 10 kW load for optimal performance.
Maintenance & Reliability
Inspect the probe cable and connector periodically for damage. Keep the ceramic tip clean from debris and contaminants. The robust stainless steel case and ceramic tip provide long service life. Regular verification of the linear range and scale factor ensures consistent monitoring accuracy.
Selection Guide & Purchasing Advice
Before ordering, confirm your system requirements: total probe length, connector type, and agency approvals. The 146055-10-02-05 uses Option: -0 2= with Miniature ClickLoc coaxial connector and standard cable. SpareTechPLC offers this probe new and original in factory packing with a 12-month warranty. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
