Bently Nevada 330877-080-37-CN 3300 XL 50 mm Extension Cable

Description

Functional transmission of high-displacement proximity signals under severe industrial conditions is managed reliably by the Bently Nevada 330877-080-37-CN extension cable. Engineered as an integral link for the 3300 XL 50 mm Proximity Transducer System, this 8.0-meter cable continuously transfers crucial dynamic vibration and position feedback from critical rotating machinery to supervisory instrumentation. Utilizing a specialized FluidLoc triaxial construction with perfluoroalkoxyethylene (PFA) insulation, it prevents process fluids from migrating through the internal core, while its outer stainless steel armor shielding protects against aggressive mechanical wear and EMI interference.

Features

• System Calibration Match: Precisely optimized for the electrical requirements of the 3300 XL 50 mm sensor line.
• FluidLoc Cable Technology: Blocks hazardous fluid bypass through the internal cable cavities to secure enclosure isolation.
• Stainless Steel Armor: Provides exceptional crush resistance and physical protection in demanding turbomachinery environments.
• Triaxial Shielding: 75 Ohm impedance matching ensures clean signals with minimal electrical attenuation.
• Broad Operating Envelope: High thermal threshold withstands intense continuous temperatures without structural degradation.

Applications

• Steam, gas, and hydro-electric turbines (radial and axial shaft movement tracking)
• Centrifugal and reciprocating compressors in oil and gas refineries
• Heavy duty industrial process pumps and fans
• Power generation and rotating machinery diagnostics

Empirical Engineering Insights

Alternative Models & Compatibility

This 8.0-meter extension cable is specifically factory-tuned for calibration loop lengths within the 3300 XL 50 mm system family. Do not mix or deploy this assembly with standard 3300 XL 8 mm or 11 mm probes, as doing so will skew the system system impedance profiles, triggering false calibration offsets and measurement errors in downstream Proximitor sensors. Total physical length configurations must match design parameters exactly to ensure tracking accuracy.

Application Pitfalls & Engineering Notes

While the stainless steel outer armor provides robust physical protection, it should not be subjected to tight-radius styling or acute pinch points. Maintain a minimum bend radius of 25.4 mm during installation. Exceeding the bend radius can crack the triaxial layers, causing internal signal anomalies and sporadic fault states on vibration monitoring cards. Although the FluidLoc technology restricts process fluid migration, physical junctions and standard terminal interfaces must still be protected from continuous liquid immersion.

Commissioning & Wiring Tips

Always verify that the specialized ClickLoc connectors are completely clean and free of ambient grease or moisture before clicking them together. Securely lock the physical mating collars to prevent intermittent signal drops during high-frequency industrial vibrations. Make sure that signal-shield continuity is consistently maintained through all junction boxes to defend the vibration signals against surrounding magnetic field contamination.
