Description

Technical Overview

The Bently Nevada 330130-085-10-05 is a high-integrity, precision-engineered 3300 XL Standard Extension Cable designed exclusively for integration within the Bently Nevada 3300 XL eddy-current proximity probe system. Manufactured by Baker Hughes (formerly Bently Nevada), this cable serves as a critical signal-transmission link between the 3300 XL proximity transducer and the 3300 XL monitor or data acquisition unit. Engineered to preserve signal fidelity across demanding industrial environments, the 330130-085-10-05 maintains strict impedance matching (50 Ω nominal), low phase shift, and exceptional electromagnetic interference (EMI) immunity—ensuring accurate vibration, position, and gap measurements essential for rotating machinery health monitoring. Its robust construction incorporates a double-shielded coaxial design with a corrosion-resistant stainless-steel braid and aluminum foil layer, delivering superior noise rejection in high-noise settings such as power generation plants, oil & gas refineries, petrochemical facilities, and large-scale industrial compressors. The cable features factory-terminated, gold-plated 7-pin MIL-C-26482 Series II connectors on both ends—male on the transducer side and female on the monitor side—guaranteeing repeatable, low-contact-resistance connections that meet stringent IEC 61000-4-3 and IEEE 1129 standards for electromagnetic compatibility. As a genuine OEM component, it is fully compliant with API RP 670 (4th Edition) for machinery protection systems and supports seamless calibration traceability to NIST standards. This extension cable is supplied in new, factory-fresh condition, rigorously tested for continuity, shielding effectiveness, and voltage withstand (≥1,000 VAC RMS), and backed by a comprehensive 24-month limited warranty against material and workmanship defects.

Detailed Specifications

Key Features

• OEM-Guaranteed Signal Integrity: Precision-matched 50 Ω impedance and ultra-low capacitance ensure minimal phase distortion and signal attenuation—critical for sub-micron displacement resolution in shaft orbit analysis and differential expansion monitoring.
• Industrial-Grade Dual Shielding: Combines high-coverage tinned copper braid (95%) with continuous aluminum foil for >100 dB common-mode noise rejection, enabling reliable operation near VFDs, switchgear, and high-voltage bus ducts.
• Extreme Environment Durability: PEEK jacket resists hydrocarbon exposure, steam cleaning, ozone degradation, and mechanical abrasion; validated for continuous service in API 612 and API 617 compressor trains.
• Gold-Plated MIL-Spec Connectors: Hermetically sealed, torque-spec’d 7-pin interfaces prevent fretting corrosion and maintain contact resistance below 10 mΩ over 500 mating cycles—ensuring long-term calibration stability.
• NIST-Traceable Calibration Support: Designed to preserve factory calibration of 3300 XL probes (e.g., 330105-02-00, 330180-50-00); included with full test report documenting shield effectiveness, VSWR, and time-domain reflectometry (TDR) results.
• Plug-and-Play Integration: Fully compatible with all 3300 XL monitors (3500/22M, 3500/42M), 3300 XL Proximitor® transducers, and legacy 3300 systems—no configuration or software updates required.
• Sustainable Lifecycle Management: RoHS 3 and REACH-compliant materials support global environmental compliance; recyclable metal content exceeds 82% by weight.

Applications

• Turbomachinery Protection Systems: Real-time shaft vibration and axial position monitoring in steam turbines, gas turbines, and hydroelectric generators per ISO 10816 and API 670 requirements.
• Oil & Gas Rotating Equipment: Critical monitoring of centrifugal compressors, pipeline pumps, and LNG train drivers operating under high-pressure, high-temperature conditions.
• Power Generation Asset Health Monitoring: Integration into Distributed Control Systems (DCS) and Machinery Protection Systems (MPS) for predictive maintenance of synchronous condensers and auxiliary drives.
• Petrochemical Process Trains: Reliable gap measurement in reciprocating compressors and gearboxes exposed to aggressive process gases (H₂S, CO₂, NH₃) and thermal cycling.
• Aerospace Ground Test Facilities: High-fidelity dynamic testing of jet engine components where EMI resilience and thermal stability are non-negotiable.
• Research & Development Laboratories: Reference-grade extension cabling for academic and industrial R&D in rotor dynamics, modal analysis, and active magnetic bearing control validation.
