Bently Nevada 330730-080-01-05 3300 XL 11 mm Extension Cable

Description

Option 080 (8.0 meters length) and Option 01 (armored coaxial cable) specify this 3300 XL 11 mm extension cable configuration — 330730-080-01-05. As a critical link in the proximity transducer chain, this 3300 XL 11 mm Extension Cable connects the 11 mm probe to a 3300 XL Proximitor sensor, facilitating continuous, non-contact measurement of radial vibration, axial position, and speed on large rotating machinery.

This configuration utilizes a 75 Ohm triaxial cable core insulated with fluoroethylene propylene (FEP) to protect signal integrity in high-temperature industrial environments. The added flexible stainless steel armor and FEP outer jacket shield the coaxial lines from mechanical abrasion, physical impact, and corrosive moisture or turbine lubricants found in industrial plants.

Features

• Option 080 specifies an 8.0-meter (26.2-foot) physical cable length to satisfy precise system loop requirements.
• Option 01 adds flexible AISI 302 stainless steel armor with an FEP outer jacket for robust mechanical shielding.
• Option 05 designates multiple agency approvals for safe deployment in hazardous locations and classified areas.
• Miniature coaxial ClickLoc connectors provide clean, tool-free locking interfaces between the probe lead and Proximitor sensor.
• Gold-plated brass connector bodies resist corrosion and ensure reliable signal conduction over extended operating cycles.

Applications

This cable is used alongside 11 mm proximity probes on heavy industrial rotating equipment such as steam turbines, gas turbines, turbo-compressors, and generators. The extended physical range of 11 mm transducer systems is highly suited for thrust (axial) position monitoring, differential expansion measurements, and rod-drop calculations in reciprocating compressors where a wider linear range is necessary. The armored jacket makes this specific cable configuration optimal for routing across exposed open-air paths, conduit bends, and high-debris zones.

Installation Guidelines

When installing the extension cable, observe the minimum bend radius limit of 25.4 mm (1.0 inch) to protect the internal triaxial conductors and outer armor from mechanical fatigue. Hand-tighten the ClickLoc coaxial connectors before applying final torque using connector-to-connector guidelines; do not exceed a maximum torque of 0.565 N-m. For wet or oil-exposed installations outside the machine casing, apply silicone self-fusing tape (Bently Nevada part number 03200006) to seal connection joints. Avoid using tape inside turbine housings where direct exposure to hot lubricating oil can degrade the adhesive structure.

Compliance and Certifications

This transducer component complies with major global industrial standards, including the European Union EMC Directive 2014/30/EU (tested to EN 61000-6-2 and EN 61000-6-4) and RoHS Directive 2011/65/EU. When combined with certified probes and Proximitor sensors under Option 05, the transducer system carries multiple international certifications for hazardous atmospheres, covering Class I Division 1 and 2, and Zone 0, 1, and 2 environments (ATEX, IECEx, and CSA).
