Quick Detail

Description

The 330930-065-02-00 3300 NSv Extension Cable is a high-fidelity, durable cable assembly engineered by Bently Nevada to reliably extend the signal path between 3300 NSv proximity probes and their associated conditioning monitors or system interfaces. As an integral component of the advanced 3300 NSv machinery condition monitoring platform, this extension cable is designed to preserve the integrity of sensitive eddy current measurement signals over extended distances, ensuring that critical data on shaft vibration, radial displacement, and axial position is transmitted without degradation. It is the essential link that provides installation flexibility, enabling precise sensor placement on rotating equipment even when the monitoring electronics are located remotely in control panels or junction boxes.

This specific Bently Nevada extension cable is characterized by a substantial total length of 6.5 meters (21.3 feet) and a compact overall case length of 60 mm at its connection points. The core of its construction is a precision 75 Ω coaxial cable with fluoroethylene propylene (FEP) insulation, a material chosen for its excellent dielectric properties and resistance to a wide range of chemicals, oils, and temperature extremes. For applications demanding extra physical protection, the cable is available with an optional flexible AISI 302 stainless steel (SST) armor, which can be supplied with or without an additional FEP outer jacket. This armored option provides superior defense against crushing, abrasion, and rodent damage in the harshest plant environments, from refinery pipe racks to offshore installations.

Applications

This 6.5-meter extension cable is essential for installations where 3300 NSv proximity probes are mounted on large equipment, such as steam turbines or centrifugal compressors, and the monitoring rack is located in a distant control room or on a separate skid. It bridges the gap without signal loss, enabling optimal sensor placement for accurate measurement while centralizing the monitoring electronics for easier access and maintenance.

Ideal for routing through challenging plant environments, the cable’s optional AISI 302 SST armor with FEP jacket provides critical protection in areas with high risk of physical damage, extreme temperatures, or exposure to corrosive chemicals and hydrocarbons. This makes it perfect for use in refinery, chemical processing, and offshore applications, where cables may be routed along pipe racks, through cable trays, or in exposed locations susceptible to abrasion and impact.

This cable serves as a key component in system expansion, upgrade, or retrofit projects. Its standardized design and 75 Ω coaxial construction ensure seamless integration and electrical compatibility when adding new monitoring points to an existing 3300 NSv system or when replacing older cabling infrastructure to improve signal reliability and system longevity.

Specifications

Competitive Advantage

1. Precision Signal Transmission Over Distance

Engineered with low DC resistance (≤ 0.1 Ω/m) and controlled capacitance (69.9 pF/m typical), this cable is optimized to minimize signal attenuation and phase shift. This ensures that the sensitive analog signals from 3300 NSv probes are delivered to the monitor with high fidelity, preserving the accuracy of vibration and position measurements critical for reliable machinery protection.

2. Robust Physical Protection for Demanding Environments

The availability of flexible AISI 302 stainless steel armor provides an exceptional level of mechanical defense against crushing, cutting, and abrasion. Combined with the chemical and thermal resistance of the FEP insulation and outer jacket, this design guarantees long-term cable integrity and reliable performance in the most punishing industrial settings, from high-vibration machinery halls to corrosive outdoor installations.

3. Guaranteed Compatibility and System Integrity

As a genuine Bently Nevada accessory designed specifically for the 3300 NSv platform, this cable guarantees perfect electrical and mechanical compatibility. It eliminates the risks associated with third-party cables, such as impedance mismatch or connector failure, ensuring the entire monitoring channel performs as specified and supports the system's diagnostic and protection functions.

4. Flexible Installation for Complex Plant Layouts

The substantial 6.5-meter length provides installers with significant flexibility to route cables neatly along optimal paths, around obstacles, and over long distances. This reduces the need for intermediate junction boxes and splices, which are potential points of failure, simplifying installation logistics and improving overall system reliability.
