Câble d'extension Bently Nevada 330930-040-00-00 3300 XL NSv

The 330930-040-00-00 is a 3300 XL NSv Extension Cable designed for use with proximity transducer systems that require high-accuracy noncontact displacement measurements in confined spaces. This high-precision coaxial cable serves as the intermediate connection link between a 3300 NSv proximity probe and a 3300 XL NSv Proximitor Sensor. It is engineered primarily for industrial machinery with tight installation constraints, such as centrifugal air compressors, refrigeration compressors, and process gas compressors. The design allows the transducer system to effectively operate in environments with counterbore, sideview, or rearview restrictions that limit standard larger probe systems. Featuring gold-plated brass ClickLoc connectors, it ensures a secure, vibration-resistant connection that prevents loosening during operation. This model is identified by part number 330930-040-00-00 and internal designation P3403893-0006.

Features

• ClickLoc Connectors: Equipped with miniature gold-plated brass coaxial connectors that lock securely into place to prevent signal loss from mechanical loosening.
• Fluoroethylene Propylene Insulation: Constructed with a durable FEP jacket to provide high insulation performance and environmental resistance.
• Interchangeability: Fully compatible and mechanically interchangeable with preceding 3300 RAM series extension cables.
• Signal Integrity: Features a nominal capacitance of 69.9 pF/m to minimize signal distortion over the total system length.

Applications

• Centrifugal air compressors and process gas compressor monitoring.
• Refrigeration compressor vibration and position tracking.
• Radial vibration and axial position measurements on small-diameter shafts.
• Tachometer, zero speed, and Keyphasor phase reference signal applications.

Technical Specifications

Installation Guidelines

• System Length Verification: Ensure that the combined physical length of the extension cable and the proximity probe equals the total length specification required by the paired Proximitor Sensor.
• Connector Protection: Use connector protectors or silicone self-fusing tape to prevent moisture and liquid ingress into the electrical connections. Note that silicone tape is not recommended if exposed directly to turbine oil.
• Bend Radius Limitation: Maintain a minimum bend radius of at least 25.4 mm (1.0 in) during routing to prevent core damage or electrical impedance alterations.
• Connector Torque: Tighten the ClickLoc connectors finger-tight to establish a secure lock. Do not exceed the mechanical limits of the locking mechanism.
