Bently Nevada 330730-080-01-00 3300 XL 11 mm Extension Cable

Description

Option 080 (8.0 meters length) and Option 01 (stainless steel armor with FEP outer jacket) specify this 3300 XL 11 mm extension cable configuration — 330730-080-01-00. This armored cabling configuration provides extensive mechanical protection against physical crushing, abrasion, and fluid ingress in high-exposure areas. By selecting Option 00, this unit is supplied as a standard non-certified configuration, intended for general-purpose applications where hazardous area certifications are not required.

The cable serves as the critical transmission path within a 3300 XL 11 mm proximity transducer system, carrying high-frequency eddy-current signals between a 1.0-meter proximity probe and a 330780 Proximitor sensor. Utilizing low-loss 75-ohm triaxial technology and gold-plated ClickLoc coaxial connectors, this 8.0-meter cable maintains high signal integrity and impedance matching across the complete 9.0-meter loop. Its physical construction makes it highly resistant to corrosive environments, moisture, and chemical exposure commonly found in turbine housings and compressor casings.

Features

• Cable Length: 8.0 meters (26.2 feet) of durable triaxial cable, perfectly matched to construct a 9.0-meter system length when paired with a 1.0-meter probe.
• SST Armor Protection: Features flexible AISI 302 stainless steel armor with an outer FEP jacket to withstand heavy mechanical stress, cutting, and crushing forces.
• Triaxial Construction: 75-ohm triaxial cable core insulated with fluoroethylene propylene (FEP) to minimize capacitance and signal attenuation.
• Robust Connectivity: Equipped with premium gold-plated brass ClickLoc coaxial connectors for a tight, corrosion-resistant, and chemically protected union.
• Standard Configuration: Provided under Option 00 (no agency approvals required) for lower cost and simpler implementation in non-hazardous industrial areas.

Applications

• Turbine shaft radial vibration and axial thrust position measurement
• High-speed turbo-compressor rotor position monitoring
• Industrial boiler feed pump and fan bearing housing protection
• Critical rotating machinery telemetry loops on 11 mm probe platforms
• Environments requiring protective armor casing against falling debris, scraping, and hot lubricants

Installation Guidelines

• Verify that the extension cable length (8.0 meters) combined with the probe length (1.0 meter) matches the Proximitor sensor's total system length (9.0 meters) to ensure accurate calibration.
• Ensure that routing curves do not exceed the minimum bend radius of 25.4 mm (1.0 in) to prevent damage to the FEP insulation or internal coaxial shield.
• Join the ClickLoc connectors firmly by hand; do not exceed the recommended maximum torque rating of 0.565 N-m (5 in-lb).
• Ensure all connector connections inside the machine case are protected. Do not use silicone self-fusing tape in direct contact with turbine lubricating oil.
• Keep signal cable runs isolated from high-voltage AC cables in distinct conduit or cable trays to minimize electromagnetic interference.

Compliance and Certifications

• CE Mark: Fully compliant with the European Union Electromagnetic Compatibility (EMC) Directive 2014/30/EU and RoHS Directive 2011/65/EU.
• EMC Standards: EN 61000-6-2 (Industrial Immunity) and EN 61000-6-4 (Industrial Emissions).
• FCC Compliance: Meets Part 15 regulations for industrial telemetry environments.
• RoHS: Meets EU Directive 2011/65/EU and China RoHS EFUP designation standards.
