Bently Nevada 330877-080-36-05 3300 XL Extension Cable 8m

3300 XL Extension Cable Bently Nevada 330877-080-36-05

Product Introduction

The Bently Nevada 330877-080-36-05 is a 3300 XL 50 mm Extension Cable designed for critical vibration monitoring systems. This 8.0-meter cable incorporates the advanced FluidLoc option, which prevents oil and other liquids from leaking through the cable interior. The cable uses 75 Ω triaxial construction with PFA (perfluoroalkoxyethylene) insulation for superior electrical performance. Furthermore, it carries multiple agency approvals (Option 05), ensuring compliance with international standards. This extension cable connects seamlessly between the 3300 XL probe and the Proximitor sensor, forming the complete measurement chain.

Technical Specifications

Electrical Characteristics

The Bently Nevada 330877-080-36-05 exhibits precise electrical parameters. The cable DC resistance from center to coaxial conductor measures 2.0 ± 0.5 Ω for the 8.0-meter length. The conductor resistance from coaxial to coaxial is 0.6 ± 0.2 Ω. These low and tightly controlled resistance values ensure accurate signal transmission without significant attenuation or degradation.

Cable Construction and Material

This extension cable features 75 Ω triaxial construction with PFA insulation. The PFA material offers excellent chemical resistance and thermal stability. Meanwhile, the FluidLoc cable option provides a liquid-tight seal that prevents oil, water, and other process fluids from migrating through the cable interior. This feature is particularly valuable in turbine, compressor, and pump applications where oil leakage could create safety hazards or environmental concerns.

Temperature Range and Environmental Durability

The extension cable operates reliably across a wide temperature spectrum. The operating and storage temperature range spans from -51°C to +200°C (-31°F to +392°F). This broad range allows installation in harsh environments near high-temperature machinery. The PFA insulation maintains its electrical properties even at elevated temperatures, ensuring consistent signal quality over time.

System Compatibility and Usage

Matching Probe and Proximitor Lengths

When using the 330877-080-36-05, ensure that the extension cable length and the probe length, when added together, equal the Proximitor sensor total length. This matching requirement is critical for accurate scaling and linearization. For example, an 8.0-meter extension cable paired with a probe of appropriate length must match the Proximitor rating. Always verify the total system length before installation.

Connection and Interface

This cable connects the 3300 XL 8 mm or 50 mm probe to the 3300 XL Proximitor sensor. The triaxial design provides excellent noise rejection, which is essential in industrial environments with electrical interference. The connectors are designed for secure mating and repeated connection cycles without performance degradation.

FluidLoc Cable Technology

Leak Prevention Benefits

The FluidLoc option is a significant advancement over standard cables. It incorporates sealing elements that block fluid migration along the cable's internal structure. Consequently, this prevents oil from leaking out of the machine through the cable interior. This feature enhances safety, reduces environmental risks, and maintains machine integrity. Additionally, it prevents contamination that could affect the cable's electrical performance over time.

Application Suitability

FluidLoc cables are particularly recommended for applications involving oil-lubricated bearings, steam turbines, and compressors. They are also valuable in installations where the cable passes through machine casings or oil sumps. The Bently Nevada 330877-080-36-05 provides peace of mind in such demanding scenarios.

Agency Approvals and Compliance

Multiple Approvals (Option 05)

This cable carries Option 05, which includes multiple agency approvals. These approvals cover CSA, ATEX, and IECEx standards, making the cable suitable for use in hazardous areas and explosive atmospheres. Always consult the specific approval documentation for detailed classification and usage conditions.

Quality and Certification

Each 330877-080-36-05 cable is manufactured in the U.S.A. under strict quality control procedures. It is supplied in original factory packaging, ensuring the cable arrives in pristine condition. The 12-month factory warranty provides additional assurance of quality and reliability.

Installation Guidelines

Cable Routing Best Practices

First, plan the cable route to avoid sharp bends, high-heat sources, and moving machinery. Maintain a minimum bend radius as specified by Bently Nevada guidelines. Next, secure the cable using appropriate clamps and supports at regular intervals. Avoid stretching or twisting the cable during installation, as this could damage the internal conductors or the FluidLoc sealing.

Connection Procedure

Connect the cable securely to the 3300 XL probe and the Proximitor sensor. Ensure the connectors are fully engaged and properly tightened. For the FluidLoc cable, verify that the sealing elements are correctly positioned before tightening. After connection, perform a continuity check to confirm proper electrical contact.

System Length Verification

Verify that the combined length of the probe and extension cable matches the Proximitor sensor rating. For the 8.0-meter cable, the probe length must complement the total required length. If the lengths do not match, the system will not provide accurate scaling and may produce erroneous readings.
