330905-00-13-10-02-CN Bently Nevada Eddy Current Sensor 3300 NSv

Bently Nevada 330905-00-13-10-02-CN 3300 NSv Proximity Probe Overview

The Bently Nevada 330905-00-13-10-02-CN belongs to the high-precision 3300 NSv Series eddy current proximity transducer family. Bently Nevada engineered this compact sensor for tight space constraints where side-view clearance or small shaft diameters restrict standard probes. The 330905-00-13-10-02-CN delivers accurate shaft vibration and axial position measurement on high-speed industrial machinery.

Comprehensive Technical Specifications

Engineering Characteristics & Advantages

• Superior Side-View Tolerances: Operates effectively near flat metal walls where standard probes experience side-view interference.
• Enhanced Chemical Resistance: PPS probe tip construction withstands corrosive atmospheres found in process compressors.
• Compact M10 Threaded Body: 130 mm overall case length with 0 mm unthreaded portion allows deep mechanical mounting.
• ClickLoc Connector Architecture: Miniature coaxial connection prevents loosening during high machinery vibration.
• Backward Compatibility: Mechanically and electrically interchangeable with legacy Bently Nevada 3300 RAM systems.

Suitable Machinery & Field Applications

• Centrifugal Process Compressors: Monitors radial vibration on high-speed shaft journals exposed to corrosive gas media.
• Small Shaft Turbomachinery: Measures axial displacement on shaft diameters under 13 mm without scale factor degradation.
• Industrial Gearboxes: Installs into tight bearing housings where side-wall proximity corrupts standard eddy current fields.
• High-Speed Pumps & Blowers: Provides continuous fluid-film bearing condition monitoring for predictive maintenance programs.

Model Cross-Selection Comparison & Technical Guidance

Engineering Selection Advice:

• Select the 330905-00-13-10-02-CN when your mounting sleeve requires a shorter 130 mm case length and your Proximitor sensor is mounted within a 1.0-meter reach without flexible metal conduit needs.
• Choose the 330905-00-25-05-01-00 variant if your installation demands a longer 250 mm case depth and stainless steel armor cable protection against mechanical crushing in harsh field environments.

Installation & Physical Mounting Protocols

• Check mounting threads to ensure clean M10x1 alignment before threading the probe into the bearing housing.
• Thread the probe case into position using a maximum initial torque of 7.5 N·m (66 in·lb) to avoid casing deformation.
• Adjust physical probe tip gap using a feeler gauge or DC voltage reading until reaching the recommended 1.0 mm (40 mils) offset (-9 Vdc to -10 Vdc baseline).
• Route FEP probe cables maintaining a minimum bend radius of 25.4 mm (1.0 in) to prevent coaxial signal attenuation.
• Hand-tighten the ClickLoc coaxial connector to complete connection without using pliers or open-end wrenches.

Diagnostic Capabilities & Onsite Troubleshooting

• DC Voltage Gap Verification: Measure DC voltage across raw signal terminals; readings outside -1 Vdc to -13 Vdc indicate incorrect physical gap or damaged tip.
• Winding Resistance Check: Verify probe resistance between center and outer conductors matches 4.2 ± 0.5 Ω at ambient temperature.
• Scale Factor Auditing: Verify 7.87 V/mm output change when moving the target in 0.25 mm increments during static bench calibration.
• Insulation Fault Diagnostics: Check insulation resistance from probe conductors to outer stainless steel casing; readings must exceed 10 MΩ.

Global PLC Spare HUB's Insight

During field machinery overhauls, the Bently Nevada 330905-00-13-10-02-CN excels in tight compressor bearing pockets. On a recent petrochemical plant turnaround, field engineers encountered side-wall interference when installing standard 8mm probes near a narrow bearing face. Upgrading to the 330905-00-13-10-02-CN eliminated side-view corruption due to its focused eddy current field, providing clean vibration signals without requiring expensive bearing housing machining.

Frequently Asked Questions

What is the primary difference between standard 3300 XL probes and 3300 NSv probes?

The 330905-00-13-10-02-CN NSv probe features a smaller tip geometry designed for tight mounting spaces and targets with small shaft diameters.

How do I troubleshoot a flatlined 0 Vdc signal output from the Proximitor sensor?

Inspect the coaxial cable continuity for open circuits and verify probe resistance reads approximately 4.2 Ω across conductors.

Can I mix a 1.0-meter probe with a 9.0-meter extension cable on a 5-meter Proximitor?

No, the total electrical length of the probe plus extension cable must match the calibrated system length (5.0 m or 7.0 m) of the Proximitor.

What torque should I apply when connecting the miniature ClickLoc coaxial connector?

ClickLoc connectors are designed for finger-tight installation; do not use hand tools to prevent damaging the miniature gold contacts.

Does this probe require special target materials to maintain accurate calibration?

Standard calibration is performed on AISI 4140 steel; using alternative target alloys requires custom ISF recalibration or scale factor correction factors.
