Bently Nevada 330130-035-01-CN 3300 XL Standard Extension Cable

Description

Option 035 (3.5 m length) and Option 01 (integrated stainless steel armor) specify this 3300 XL standard extension cable configuration — 330130-035-01-CN. This configuration utilizes a 75-ohm coaxial cable protected by FEP-insulated stainless steel armor to offer excellent defense against severe physical wear, abrasion, and cutting forces, outperforming standard non-armored cables in rugged industrial zones. The cable is terminated with gold-plated ClickLoc coaxial connectors (one male, one female) for stable signal transmission within the machinery monitoring loop.

This variant is specifically supplied with the -CN suffix, signifying compliance with China hazardous area regulations (NEPSI and CCC approvals) for integration into plant machinery protection systems in restricted zones. The cable serves as a critical link between a 3300 XL 8 mm proximity probe and a 3300 XL Proximitor sensor, ensuring the mechanical vibration and axial position readings are transmitted with minimal attenuation or impedance mismatch.

Features

• 3.5-Meter Length (Option 035): Calibrated length option representing 3.5 m (11.5 ft) of physical extension to match multi-meter system requirements.
• Stainless Steel Armor (Option 01): Helically wrapped stainless steel armor with protective outer FEP coating preserves cable structure against shearing, crushing, and fluid ingress.
• Gold-Plated ClickLoc Connectors: Corrosion-resistant coaxial terminals with standard ClickLoc mechanism prevent accidental disconnects.
• -CN Country Package: Certified for hazardous environments within China under NEPSI and CCC standards.
• Wide Temperature Range: Standard insulation withstands operating temperatures down to -52 degC and up to +177 degC.

Applications

The armored extension cable is deployed on critical industrial machinery within high-exposure sectors such as power generation, oil and gas, and petrochemical processing. Typical installations include:

• Steam and gas turbine shaft vibration monitoring systems.
• Centrifugal compressor axial displacement and thrust position sensing.
• Gearbox high-speed shaft vibration and casing relative motion measurements.
• Large electric motor and generator bearing housing protection assemblies.

Installation Guidelines

• Connector Tightening: Ensure ClickLoc coaxial connectors are tightened finger-tight only. Do not apply wrenches or pliers, as excessive mechanical force will damage the gold contact plating and structural sleeves.
• Minimum Bend Radius: Maintain a minimum bend radius of 25 mm (1.0 in) along the armored cable to avoid kinking the internal coaxial shield or fracturing the outer FEP armor jacket.
• Cable Routing: Always route the armored cable away from high-voltage electrical conduits, major electromagnetic interference sources, or areas with persistent pooling water or corrosive fluids.
• Calibrated Length Check: Confirm that the combined physical length of the proximity probe and this extension cable equals the total calibrated length specified on your Proximitor sensor housing.

Compliance and Certifications

• NEPSI: Explosion protection certified for industrial hazardous locations in the People's Republic of China.
• CCC: China Compulsory Certificate standard approval for high-demand plant machinery protection.
• RoHS: Compliant with international environmental directives limiting hazardous substance usage.
