Kabel Perpanjangan Bently Nevada 330930-040-03-00 3300 NSv

Description

The Bently Nevada 330930-040-03-00 is a highly specialized 4.0-meter (13.1 feet) 3300 NSv Proximity Extension Cable. It is engineered as a core component of the 3300 XL NSv Proximity Transducer System, which is specifically optimized for small shaft targets, limited counterbore clearances, and restrictive side-view geometries common in high-density turbomachinery installations.

Distinct from armored variants, this configuration features a lightweight, high-flexibility coaxial build without stainless steel armor. It is designed for clean, routed conduit installations or internal machine environments where mechanical shielding is redundant but space-saving and effortless routing are critical. To protect signal integrity, it comes equipped with integrated connector protectors over the gold-plated brass ClickLoc interfaces, preventing moisture or liquid ingress from inducing signal drift at the connection point. This cable seamlessly matches the impedance requirements of the 3300 XL NSv Proximitor Sensor and offers drop-in legacy replacement compatibility for standard 3300 RAM transducer lines.

Features

• 4.0-Meter Length Optimization: Accurately calibrated to build standard 5.0m or 7.0m total system lengths when paired with matching 1.0m or 3.0m NSv probes.
• Unarmored Design (03 Option): Strips away bulky outer stainless steel armor to offer maximum flexibility, a tighter effective installation volume, and lighter weight—ideal for densely packed conduit routing.
• Integral Connector Protectors: Features pre-installed boots over the miniature connectors to ensure long-term shielding against turbine oils and humidity.
• ClickLoc Interlocking Interconnects: Equipped with gold-plated brass ClickLoc connectors that lock into place, preventing accidental loosening under severe high-frequency machinery vibration.
• Exceptional EMI/RFI Shielding: The 75-ohm FEP insulation core effectively isolates weak proximity signals from industrial electro-magnetic interference.
• Direct Legacy Upgrades: Backwards mechanically and electrically interchangeable with traditional Bently Nevada 3300 RAM sensor extension cables.

Applications

• Small Shaft Eddy-Current Measurements: Radial vibration and shaft position monitoring on rotating machinery with shaft diameters under 51 mm (2.0 in).
• Tight-Clearance Turbomachinery: Centrifugal air compressors, process gas compressors, and industrial refrigeration compressors with constrained internal probe mounting.
• Thrust Measurements on Small Targets: Axial position tracking on flat target surfaces smaller than 15 mm (0.6 in).
• Turbine Supervisory Instrumentation (TSI): Speed sensing, zero-speed gating, and phase reference (Keyphasor) signal routing within clean-conduit networks.

Technical Specifications

Installation Guidelines

• Impedance and System Tuning: Ensure the overall total electrical length of the proximity probe and this 4.0m extension cable matches the specification labeled on the 3300 XL NSv Proximitor Sensor (typically 5.0m or 7.0m total system lengths).
• Connection Torque Limit: Secure the ClickLoc connectors finger-tight until they lock. Do not use heavy-handed mechanical tools to tighten, as excess torque can damage the internal gold-plated pins.
• Routing Bend Safeguards: Always maintain a layout route with a minimum bend radius of 25.4 mm. Sharp pinching or kinking on unarmored FEP cables can permanently alter cable capacitance, destroying calibration accuracy.
• Sealing Application: Slide the integrated connector protector firmly over the mated connection to guarantee an airtight, fluid-resistant boundary.

Compliance and Certifications

• EMC Directive: 2014/30/EU Compliance.
• RoHS Directive: 2011/65/EU and China RoHS (15-year EFUP designation).
• Functional Safety Standards: SIL 2 capable when integrated into approved safety instrumented loops.
