330130-070-12-05 Bently Nevada 7.0m Extension Cable

Product Overview

The 330130-070-12-05 is a premium Bently Nevada 3300 XL 8mm proximity transducer extension cable. It provides critical, low-loss signal transmission between an eddy current proximity probe and a 3300 XL Proximitor sensor. Engineered for critical machinery protection systems, it delivers stable vibration and position monitoring data on high-speed rotating assets like steam turbines and compressors.

Core Features

• 7.0-Meter Length: Precision-calibrated length matching specific 3300 XL system tuning requirements.
• Stainless Steel Armor: Heavy-duty flexible armor protects internal coaxial cores from mechanical crushing and cutting.
• Fluid-Resistant Seals: FluidLoc technology with integrated connector protectors seals out corrosive oils, water, and aggressive solvents.
• Click-Lock Design: Coaxial connectors match gold-plated engineering specs for rapid, secure field mating.

Technical Specifications

Engineering Installation Guide

• Total Loop Length Matching: Always combine this 7.0m cable with a 1.0m probe to complete an 8-meter system, or match according to Proximitor calibrations.
• Bend Radius Control: Maintain a minimum bend radius of 25.4 mm (1.0 in). Tight kinks disrupt coaxial capacitance and cause severe calibration errors.
• Cable Weight Support: Secure long cable runs using proper conduits or clamps to prevent the cable's own weight from straining the probe connection or connectors.
• Connector Insulation: Use standard silicone connector wrap or specialized Bently Nevada connector protectors to isolate connections from contact with machine ground.

Technical FAQs

Q1: What do the specific suffix codes (-070-12-05) indicate for this cable?
A1: -070 specifies a total cable length of 7.0 meters. -12 specifies a FluidLoc armored cable equipped with a connector protector. -05 designates standard global hazardous area safety approvals (ATEX, IECEx, CSA).

Q2: Why is isolating the coaxial connectors from machine ground critical during installation?
A2: If a connector touches the metal frame of a machine, it creates an unintended ground loop. This introduces electrical noise that disrupts the Proximitor signal, resulting in false vibration spikes or false trip commands.

Q3: Can I cut or splice this extension cable to match short conduit runs?
A3: No. Proximity extension cables are factory-trimmed to an exact electrical capacitance. Splicing or changing the physical length alters the circuit impedance, destroying the system calibration and making precise voltage measurements impossible.
