Quick Detail

Description

The 330130-085-01-CN is a high-performance, armored Standard Extension Cable engineered for the Bently Nevada 3300 XL machinery monitoring system. This critical component establishes a robust and reliable signal pathway between 8 mm proximity probes and the Proximitor condition monitoring modules. It is specifically designed to transmit high-frequency eddy-current displacement signals with uncompromising fidelity, ensuring accurate measurement of vital parameters such as radial vibration, axial thrust position, and Keyphasor speed reference for the protection of critical rotating equipment like turbines, compressors, and large pumps.

A key differentiator of the 330130-085-01-CN model is its durable armored cable construction with a standard length of 8.5 meters (27.9 feet). The armored sheath provides superior mechanical protection against crushing, abrasion, and exposure to oils and chemicals commonly found in industrial environments. Internally, the cable features a precision 75Ω triaxial design. This architecture is essential for preserving signal integrity, as its multiple layers of shielding effectively combat electromagnetic interference (EMI) and radio-frequency interference (RFI) prevalent in facilities such as power plants and petrochemical complexes.

Applications

The 330130-085-01-CN is widely used for continuous protection monitoring of high-value rotating equipment in sectors like power generation (steam/gas turbines) and oil & gas (centrifugal compressors, feed pumps). Its 8.5-meter armored cable length is ideal for routing across large turbine decks and through industrial cable trays where it is exposed to potential physical damage. By reliably connecting proximity probes to monitoring systems, it transmits essential vibration and position data, enabling the early detection of faults such as rotor imbalance, misalignment, and incipient bearing wear to prevent catastrophic machinery failures.

This extension cable is a preferred solution for installations in classified hazardous areas within petrochemical refineries, chemical processing plants, and offshore platforms. Its robust construction and relevant agency approvals (CSA, ATEX, IECEx) make it suitable for integration into intrinsically safe or explosion-proof loops. The 75Ω triaxial design ensures that sensitive displacement signals remain clear and uncontaminated by electrical noise from high-power equipment like large motors and variable frequency drives (VFDs), delivering accurate machine health data to control rooms even in electrically noisy environments.

Specifications

Competitive Advantage

1.Superior Durability and Mechanical Protection

The defining advantage of this model is its rugged armored cable design. Compared to standard unarmored variants, the armored cable provides unparalleled protection for the internal conductors against crushing, cutting, abrasion, and exposure to oils and chemicals. Combined with factory-installed connector protector caps, this design addresses the most common field failure points—connector contamination and cable damage—thereby significantly extending the mean time between failures (MTBF) for the entire monitoring loop and reducing total cost of ownership.

2.Comprehensive Industry Compliance and Plug-and-Play Interchangeability

The 330130-085-01-CN strictly adheres to international standards like API 670 and carries critical agency approvals such as CSA, ATEX, and IECEx, meeting the requirements for hazardous and demanding industrial applications worldwide. Crucially, it offers complete interchangeability within the Bently Nevada 3300 XL system. Maintenance teams can directly swap probes, extension cables, or Proximitors from different production batches without needing to recalibrate the system. This "plug-and-play" capability greatly simplifies spare parts inventory management and dramatically reduces critical machinery downtime during repairs or replacements.

3.Exceptional Signal Integrity in Electrically Hostile Environments

Utilizing a precision 75Ω triaxial structure with low per-unit capacitance, this extension cable is engineered to maintain superior signal integrity in high-interference zones. Its multiple shielding layers effectively suppress electromagnetic interference (EMI/RFI) from sources like large motors, variable frequency drives (VFDs), and power switching equipment. This ensures the vibration and positional data received by the monitoring system is a true, noise-free representation of machine health, preventing false alarms or missed alerts that can occur with inferior cables. This reliability forms a trusted foundation for accurate diagnostics and protection decisions.
