Bently Nevada 330930-040-00-05 3300 NSv Extension Cable

Description

330930-040-00-05: 3300 NSv extension cable configured with a 4.0 m total length (Option 040), standard unarmored coaxial cable (Option 00), and a Multiple Approvals certification package (Option 05). This cable provides the critical connection path between a 3300 NSv proximity probe and a 330980 Proximitor sensor, completing the eddy-current transducer circuit for small-target and restricted-clearance industrial machinery.

Unlike armored options (such as Option 01 or Option 02) which feature an outer stainless steel protective sleeve, this Option 00 configuration is unarmored. This makes it lighter and more flexible for installation within protective conduits or narrow pathways where tight bends are required. The Option 05 designation provides ATEX, IECEx, and CSA hazardous area certifications, allowing standard installation in Class I, Division 2 and Zone 2 environments.

Features

• 4.0 meters (13.1 feet) calibrated length matching system requirements to avoid measurement scale errors.
• Unarmored design (Option 00) for high mechanical flexibility and ease of routing in standard industrial conduits.
• Multiple Approvals package (Option 05) covering global hazardous area standards including ATEX, IECEx, and CSA.
• Gold-plated brass ClickLoc coaxial connectors establishing secure electrical contact under constant machine vibration.
• Built-in physical compatibility with both previous-generation 3300 RAM probes and 3300 NSv proximity probes.
• 45 g/m cable weight minimizing structural load on cable trays and supporting fixtures.

Applications

• Connection of 3300 NSv probes in centrifugal air compressors and refrigeration compressors.
• Signal transmission in space-constrained aeroderivative gas turbines and process gas equipment.
• Non-contact shaft vibration and axial position measurement on shafts smaller than 51 mm (2 in).
• Installation in Zone 2 and Class I, Division 2 hazardous industrial environments.

Installation Guidelines

• Maintain a minimum bend radius of at least 25.4 mm (1.0 in) during installation to protect coaxial cable integrity.
• Ensure connectors are fully locked in place (finger tight is recommended; maximum torque is 0.56 Nm or 5 in lb).
• Apply protective connector sleeves or self-fusing silicone tape to prevent environmental contamination at the joints.
• Avoid routing cables near high-voltage sources to reduce electromagnetic interference.

Compliance and Certifications

• EMC Standards: EN 61000-6-2 (Industrial Immunity), EN 61000-6-4 (Industrial Emissions)
• RoHS: European Directive 2011/65/EU and China RoHS (15-year EFUP)
• Functional Safety: SIL 2 (HFT = 0), SIL 3 (HFT = 1) certified when integrated in standard configurations
• Hazardous Areas: ATEX/IECEx/CSA Zone 0/Zone 2 and Class I, Div 2 approvals under Option 05
