Bently Nevada 330130-040-03-CN 3300 XL Standard Extension Cable

Description

330130-040-03-CN: 3300 XL standard extension cable, featuring Option 040 for a 4.0 m cable length, Option 03 for stainless steel armor with connector protector, and suffix -CN for China hazardous area approval (NEPSI, CCC). This cable provides the critical connection path between the 3300 XL 8 mm proximity probe and the 3300 XL Proximitor sensor, conveying the high-frequency eddy-current signals with minimal loss or interference.

Unlike standard unarmored configurations such as Option 00 or Option 02, Option 03 adds an FEP-jacketed stainless steel armor sheath to defend the internal triaxial conductors against mechanical damage, crushing, and cutting hazards. Furthermore, while standard Option 05 configurations provide general ATEX and IECEx agency approvals, the -CN suffix specifies China-specific NEPSI and CCC certifications required for petrochemical, refinery, and power generation installations operating within China.

Features

• Option 040 length: 4.0 meters (13.1 feet) total length, designed to balance total transducer system length.
• Option 03 construction: Stainless steel spiral armor jacketed with FEP insulation, paired with a fluorosilicone connector protector.
• ClickLoc connectors: Corrosion-resistant, gold-plated brass connections that lock finger-tight without tools.
• -CN certification package: Complete compliance documentation under NEPSI and CCC explosion-protection frameworks.
• Impedance rating: Nominal 75 ohm triaxial system impedance matching 3300 XL 8 mm probes and Proximitor sensors.

Applications

• Shaft vibration monitoring in steam and gas turbines.
• Axial position sensing in industrial centrifugal compressors.
• Rotational speed and phase reference (keyphasor) tracking in large industrial motors.
• Heavy-duty pump and fan casing vibration diagnostic systems.

Installation Guidelines

• Keep connections clean and dry. Avoid over-tightening; the ClickLoc connectors require finger-tight torque only (the connectors will "click" when tight).
• Maintain a minimum bend radius of 50.8 mm (2.0 inches) for armored cable to prevent damage to the FEP coating and stainless steel sheath.
• Route extension cables through protective conduit if additional mechanical isolation is required outside the pre-installed armor.
• Seal outer connections using the connector protector sleeve to protect the connection from machine fluids and moisture.

Compliance and Certifications

• NEPSI: Zone 0/1/2 Hazardous Area Certification (Ex ia IIC T4...T1 Ga/Gb)
• CCC: China Compulsory Certification (explosion protection)
• RoHS: Compliant with standard industrial environment materials restriction
