Product Overview

The Bently Nevada 330905-00-10-05-02-CN serves as the critical signal link in a 3300 XL Proximity Transducer System. This extension cable connects 3300 XL 8 mm or 11 mm probes to their respective Proximitor® sensors, ensuring the high-fidelity transmission of eddy current displacement signals. Engineered to maintain tight electrical impedance, it prevents signal attenuation and phase shifts that could compromise vibration data. This cable features high-density shielding and a specialized protective sleeve, allowing it to function reliably in the oil-soaked and high-temperature environments typical of turbine enclosures and compressor housings.

Engineering Advantages

The 330905-00-10-05-02-CN utilizes specific design elements to eliminate common signal failures in machinery protection circuits:

• ClickLoc™ Interconnect Stability: The miniature coaxial connectors feature a positive-locking ClickLoc™ mechanism. This design prevents the cable from vibrating loose—a common cause of intermittent "NOT OK" status in turbine racks—and maintains a gas-tight electrical contact.

• High-Temperature Fluoropolymer Insulation: The cable employs premium insulation materials rated for continuous operation up to +180 °C. This thermal resistance prevents the cable jacket from becoming brittle or melting when routed near hot steam lines or machinery casings.

• Advanced EMI/RFI Shielding: The high-coverage braided shield creates a Faraday cage around the signal conductor. This design rejects electromagnetic interference from nearby heavy-duty motors and variable frequency drives (VFDs), ensuring that only pure shaft vibration data reaches the Proximitor® sensor.

• Integrated Protective Sleeving: The 0.5m sleeve provides mechanical reinforcement at the connection point. It protects the cable from abrasion and prevents sharp bends that could alter the cable's electrical capacitance and degrade system calibration.

FAQs

• Is the Bently Nevada 330905-00-10-05-02-CN brand new?

  Yes. We supply the 330905-00-10-05-02-CN in 100% Brand New and Original condition. Each cable arrives in factory-sealed packaging, ensuring it meets Bently Nevada's strict calibration and durability standards.

• Does this cable work with non-3300 XL probes?

  The 330905 series is specifically calibrated for the electrical characteristics of the 3300 XL 8 mm and 11 mm systems. Using this cable with legacy (non-XL) systems or different probe diameters may cause calibration errors and inaccurate vibration readings.

• What is the significance of the "CN" version?

  The "CN" suffix confirms that the cable adheres to China-specific regulatory and agency approvals. Technically, it maintains the same high performance and material quality as the standard international 330905 extension cable.

• How do I ensure the system remains calibrated with this cable?

  Bently Nevada 3300 XL systems typically require a total electrical length of 5.0 or 9.0 metres. You must ensure the combined length of your probe lead and this extension cable matches the specific calibration of your Proximitor® sensor (e.g., a 1.0m probe lead requires a 4.0m or 8.0m extension, while this 1.0m cable is usually part of a customized short-reach assembly).
