3300 XL system matching – Designed for the 8 mm proximity transducer chain, ensuring proper impedance and phase for accurate displacement readings.
Low noise, stable signal – Shielded, impedance‑matched construction to keep eddy‑current signals clean in electrically “busy” areas.
Rugged for industrial use – Typically handles wide temperatures and vibration; suitable for compressors, steam/gas turbines, and high‑load gearboxes.
Drop‑in maintenance – You might notice that replacement is straightforward during outages; connectors mate directly to the probe and Proximitor.
Predictive maintenance ready – Preserves the fidelity needed for orbit, shaft vibration, and thrust position monitoring on API 670 style systems.
| Brand / Model | Bently Nevada 330980-51-00 (3300 XL extension cable) |
| HS Code | 8544.20 (Coaxial cable) |
| Power Requirements | None (passive signal cable between probe and Proximitor) |
| Operating Temperature | Typically −51 °C to +177 °C for the cable; Proximitor location recommended −35 °C to +85 °C |
| Signal I/O Types | Impedance‑matched coax for eddy‑current proximity transducer signals (probe ↔ Proximitor) |
| Communication Interfaces | Not applicable (analog transducer link) |
| Installation Method | Inline between 3300 XL probe and 3300 XL Proximitor; route in conduit or tray, observe bend radius, bond shield at Proximitor end |
Typically used in rotating‑equipment monitoring where shaft vibration, radial position, and thrust measurements are critical:
Gas/steam turbines and generators (bearing and thrust position)
Integrally geared and centrifugal compressors (API 617/670 environments)
Large pumps, fans, and blowers in petrochemical and power plants
Gearboxes and paper machine rolls where stability and low noise matter
Reliability under load – From my experience, the 3300 XL cabling holds up better in high‑heat bays and near high‑current drives.
Guaranteed system compatibility – Correct impedance match with 3300 XL probes and the 330103 Proximitor sensor.
Fewer false alarms – Clean signal path helps reduce nuisance trips when your monitors trend on tight thresholds.
Lower lifecycle cost – Stable calibration means fewer recalibrations and faster turnarounds during outages.
Practical support – We can pre‑check part options against your machine train and cable routing drawings before you order.
Environment – Mount Proximitor in a ventilated cabinet (IEC/NEMA rated), keep away from high‑frequency drives where practical.
Cable routing – Use metallic conduit or tray, maintain minimum bend radius, and avoid parallel runs with power cables.
Shielding/grounding – Bond cable shield at the Proximitor end only to prevent ground loops; keep probe end floating.
Connections – Seat connectors fully; torque per OEM guidance. You might notice that a half‑turn more can dramatically improve noise immunity.
Routine checks – Inspect insulation and connector boots quarterly; clean with non‑residue solvent; verify loop integrity during planned outages.
Calibration – Perform system verification with a calibration fixture at the monitor rack; firmware updates apply to monitors, not the cable.
Manufacturing typically to ISO 9001 quality standards
CE and RoHS compliance for materials and construction
Designed for use in API 670 style protection systems
Warranty: 365 days (replacement or repair as applicable)
