Bently Nevada 330171‑XX‑XX‑10‑02‑05 & 142824‑100

Product Description

The 330171‑XX‑XX‑10‑02‑05 is a 3300 XL series eddy‑current proximity probe from Bently Nevada, and 142824‑100 is its matched triaxial extension cable. This complete transducer assembly detects clearance distance between probe tip and rotating shaft surface. It works together with 3300 XL Proximitor sensor to output linear gap‑voltage signal. The probe adopts hermetically sealed stainless‑steel housing, PPS tip material, ClickLoc quick‑lock coaxial connector; the extension cable is 75‑ohm triaxial cable with FEP insulation for harsh industrial environments. The full set is used for non‑contact shaft position and vibration measurement of rotating equipment.

Product Features

• Eddy‑current non‑contact measurement, no mechanical wear on rotating shaft surface
• Linear gap‑voltage output for radial vibration, axial thrust position and shaft offset
• ClickLoc quick‑connect triaxial connector for probe‑cable assembly
• Hermetically sealed probe construction, resistant to humidity, oil mist and industrial dust
• Matched electrical length: probe plus 142824‑100 extension cable matches Proximitor requirement
• Compatible with Bently Nevada 3500 monitoring rack system
• Wide operating temperature range, suitable for turbine and compressor local installation
• Interchangeable within 3300 XL system without extra calibration

Application Scenarios

• Vibration and thrust monitoring for steam turbine, gas turbine in power plant
• Centrifugal compressor condition monitoring in petrochemical industry
• Large pump, fan and rotating machinery protection system
• Keyphasor speed and phase reference measurement for rotating shafts
• On‑line machine protection integrated with Bently 3500 rack
• Predictive maintenance for high‑speed rotating equipment

Common Problems & Troubleshooting

• Abnormal gap voltage reading: Check probe installation gap; inspect mechanical runout of shaft target surface; confirm no metal debris on probe tip; verify correct matching of probe‑cable‑Proximitor electrical length.
• No signal output / zero reading: Inspect 142824‑100 extension cable for crush, crack or insulation damage; re‑seat ClickLoc connectors; check Proximitor power supply.
• Unstable / noisy vibration signal: Check triaxial cable routing, avoid parallel laying with high‑power power cables; inspect connector pin contamination or loose connection; verify proper cable strain relief installation.
• Probe physical damage: Check for shaft rub impact to probe tip; verify mounting thread tightness; avoid over‑torque during installation.
• System mismatch alarm in 3500 rack: Confirm full assembly part numbers; ensure probe, 142824‑100 extension cable and Proximitor belong to same 3300 XL series; do not mix non‑XL components.
