Bently Nevada 330102‑00‑28‑10‑02‑05 — 3300‑XL 8 mm Armored Eddy‑Current Proximity Probe

Description

Bently Nevada 330102‑00‑28‑10‑02‑05 — 3300‑XL 8 mm Armored Eddy‑Current Proximity Probe

Product Overview

The 330102‑00‑28‑10‑02‑05 is an armored full‑thread eddy‑current proximity probe within Bently Nevada 3300‑XL 8 mm transducer family. It converts physical gap displacement between probe tip and metallic rotating target into impedance signals for matching proximitor module. Compliant with API 670, this armored‑cable probe executes radial vibration, axial thrust‑position and auxiliary Keyphasor reference measurements for critical turbomachinery protection and predictive condition‑monitoring applications. The integrated metal armor provides superior mechanical protection for field environments with cable abrasion, crush and pull‑force risks.

Critical Compatibility Warning

• Only compatible with 3300‑XL 8 mm proximitor (330180‑xx‑00) and 8 mm Microdot / ClickLoc extension cables (330130‑xx‑xx‑00).
• Not interchangeable with 11 mm probe series or NSv transducer series.
• Total system cable length = probe integral pigtail length + extension cable length, must strictly match the rated total‑system length of paired 8 mm proximitor. Incorrect total cable length will cause scale‑factor deviation and measurement error.
• Works with 3500/42M, 3300/12, 3300/15 monitor racks for alarm, trip and trending functions.

• 2.8‑inch (71.1 mm) full‑thread body: Fits medium‑depth counter‑bore mounting holes, flexible penetration‑depth adjustment during commissioning.
• Stainless‑steel armored cable construction: Excellent resistance to abrasion, mechanical crushing, pull stress and oil erosion for harsh field installations.
• 1.0 m built‑in armored pigtail cable: Short pre‑attached armored segment, flexible to match different system total‑length requirements by adding extension cables.
• Standard 2.0 mm linear measurement range: Suitable for shaft radial vibration and axial thrust‑position monitoring.
• Wide temperature tolerance ‑35 °C ~ +175 °C: Resists oil‑mist and high‑temperature casing environment inside turbines and compressors.
• ClickLoc miniature coaxial interface: Secure quick‑lock mating for 330130‑xx‑xx‑00 8 mm extension cables.
• Multi‑agency intrinsic‑safety certification: Approved for hazardous classified zones when assembled inside complete certified 3300‑XL transducer loop.
• Good interchangeability within 3300‑XL 8 mm family, no mandatory component‑pairing requirement.

Typical Application Scenarios

• Steam / gas turbine vibration & thrust‑position protection loops requiring mechanically‑protected probe cable

Installation and Configuration Guide

Warning: Installation must be performed by qualified instrumentation technicians. Always refer to original Bently Nevada 3300‑XL official manual as primary reference document.

1. Mechanical Probe Mounting
   • Screw the 3/8‑24 UNF full‑thread armored probe into casing counter‑bore hole; fasten lock‑nut on outer threaded section after gap setting.
   • Maintain probe‑tip perpendicular alignment against metallic shaft target; tilt angle will degrade linear‑range performance and measurement accuracy.
   • Ensure sufficient mechanical clearance; prevent probe‑to‑rotor collision under full shaft thermal‑growth and vibration excursion.
   • Route armored cable with proper support clamps; avoid sharp bending radius for armored sleeve; do not concentrate mechanical stress right at cable‑to‑probe transition point.
2. Connector Mating & Torque Control
   • Align ClickLoc pin positions before insertion; do not force connector mating.
   • Tighten ClickLoc connector to manufacturer‑specified torque value. Over‑torque will damage pins; under‑torque causes intermittent signal faults.
   • Never connect or disconnect transducer cables while proximitor power supply is active.
3. System Total‑Length Validation
   • Calculate total transducer cable length = probe integral pigtail length + extension cable(s) length.
   • Confirm calculated total length matches the rated cable length of installed proximitor. Mismatch will produce incorrect scale‑factor output.
4. System Commissioning Test
   • Complete full transducer loop wiring, power on proximitor.
   • Perform static gap calibration test with calibration fixture, verify output voltage and scale‑factor performance.
   • Confirm Not‑OK fault status is cleared after correct wiring.
5. Maintenance & Troubleshooting
   • Inspect ClickLoc connectors for dirt, corrosion and loose connection during machinery turnaround.
   • Check armored sleeve for dents, cracks and abrasion damage; verify inner insulation integrity.
   • Signal drift or intermittent Not‑OK alarms may indicate defective probe / armored cable or poor ClickLoc contact. Replace complete probe assembly; field repair of armored probe cable is not recommended.
6. Hazardous‑Area Installation Notes
   • For ATEX / IECEx classified‑zone deployment, strictly follow 3300‑XL intrinsic‑safety requirements covering cable specification, shielding grounding and chassis‑grounding rules.

Supplementary Remark

330102‑00‑28‑10‑02‑05 is a 3/8‑24 UNF full‑thread armored 3300‑XL 8 mm proximity probe with 2.8‑inch (71.1 mm) case length, 1.0 m stainless‑steel armored integral pigtail cable and ClickLoc connector. It is engineered for applications requiring enhanced cable mechanical protection and must pair exclusively with standard 8 mm‑series proximitor and extension‑cable assemblies. Prior to commissioning, cross‑check part‑number configuration, 3/8‑24 UNF thread dimension, armored‑cable length, connector type and total‑system cable length against project BOM and mechanical drawings.
