Description

Technical Overview

The Bently Nevada 3300 NSv Extension Cable (Model: 330930-040-05-05) is a precision-engineered component designed for seamless integration within the 3300 Series monitoring systems—widely deployed in mission-critical rotating machinery protection applications across oil & gas, power generation, chemical processing, and industrial manufacturing facilities. This extension cable serves as a high-fidelity signal conduit between proximity probes and前置 monitor modules, ensuring minimal signal attenuation, noise immunity, and phase integrity over extended distances—critical for accurate vibration, position, and speed measurements.

Engineered to meet stringent IEC 61000-4 electromagnetic compatibility (EMC) standards and conforming to API 670 (4th Edition) requirements for machinery protection systems, the 330930-040-05-05 features low-capacitance, double-shielded coaxial construction with a robust polyurethane jacket rated for continuous operation in harsh industrial environments (-40°C to +85°C). Its precisely calibrated impedance (50 Ω nominal) and factory-verified length (4.0 meters) eliminate field tuning and reduce commissioning time while maintaining the system’s overall calibration traceability to NIST standards.

Key Features

• Optimized Signal Integrity: Low-noise, double-braided shield + foil layer ensures >90 dB common-mode rejection and superior EMI/RFI immunity in electrically noisy plant environments.
• Rugged Industrial Design: Oil-, chemical-, and abrasion-resistant polyurethane jacket with reinforced strain relief at both connectors for extended service life in demanding mechanical installations.
• Plug-and-Play Compatibility: Fully compatible with all 3300 NSv monitors, 3300 XL probes, and legacy 3300 series infrastructure—no firmware updates or configuration changes required.
• Calibration-Ready: Factory-tested and documented for system-level sensitivity and frequency response compliance, supporting predictive maintenance and regulatory audit readiness.
