Description

Technical Overview

The Bently Nevada 84661-35 Armoured Extension Cable is a high-integrity signal transmission solution engineered for demanding industrial environments where reliability, electromagnetic immunity, and mechanical durability are non-negotiable. Designed specifically for integration with Bently Nevada’s 3500/40M and other compatible monitoring systems, this cable ensures precise, low-noise transmission of vibration, position, and temperature signals from proximity probes and sensors to monitoring racks—critical for maintaining asset health in rotating machinery applications.

Constructed with double-shielded twisted-pair conductors and a robust stainless steel interlocked armour, the 84661-35 delivers exceptional resistance to EMI/RFI interference, crushing forces, abrasion, and oil exposure—common challenges in power generation, oil & gas, petrochemical, and heavy manufacturing facilities. Its PVC outer jacket meets UL AWM 20276 standards and offers flame-retardant performance suitable for both indoor and controlled outdoor conduit runs. The cable features precision-matched impedance and low capacitance to preserve signal fidelity over extended distances up to 100 meters without degradation or calibration drift.

Key Features

• Stainless Steel Interlocked Armour: Provides superior mechanical protection against impact, crushing, and rodent damage—ideal for harsh plant-floor installations.
• Double-Shielded Construction: Combines foil + braided copper shielding for maximum EMI/RFI rejection in electrically noisy environments (e.g., near VFDs, switchgear, or large motors).
• Pre-Terminated with Industry-Standard Connectors: Equipped with ruggedized 10-32 UNF threaded connectors on both ends for secure, repeatable mating with Bently Nevada 3500 series monitors and probe extension interfaces.
• Temperature & Chemical Resistance: Rated for continuous operation from –40°C to +85°C and resistant to hydrocarbons, lubricating oils, and common industrial solvents.
• Traceable Calibration Integrity: Designed to maintain system-level accuracy per API 670 (4th Edition) and ISO 10816 standards when used within specified probe-cable-monitor configurations.
