Bently Nevada 84661-20 3300 XL Interconnection Cable

Description

The 84661-20 is a high-frequency, coaxial interconnection cable designed for use in 3300 series proximity transducer systems. This cable facilitates the signal path between the Proximitor sensor and the proximity probe, ensuring signal integrity in vibration and position monitoring applications for rotating machinery. This specific configuration provides a total length of 6.0 meters, allowing for extended routing distances between monitoring components and the sensor housing.

This interconnection cable utilizes high-grade, fluorocarbon-jacketed coaxial construction to protect against chemical and environmental degradation in industrial settings. The cable assembly includes the necessary connectors to maintain low-impedance connections, which is critical for maintaining accurate gap voltage readings and preventing signal attenuation in critical monitoring loops. It is compatible with 3300 XL systems and standard proximity probes requiring extension cabling.

Features

• Total cable length of 6.0 meters
• Coaxial construction for noise immunity and signal integrity
• Fluorocarbon jacket for resistance to oil, moisture, and chemical exposure
• Designed for compatibility with 3300 series proximity transducer systems
• Integrated connector ends for installation with standard Bently Nevada sensor housing and Proximitor interfaces

Applications

• Radial vibration monitoring on steam and gas turbines
• Axial position (thrust) measurement in centrifugal compressors
• Rotary equipment protection in oil and gas, petrochemical, and power generation facilities
• Turbomachinery monitoring chains where extended cable runs between probe and Proximitor are required

Installation Guidelines

Ensure that the coaxial cable is routed away from high-voltage AC lines and electromagnetic interference sources to prevent signal noise. Use protective conduit if the cable is exposed to mechanical abrasion or high-heat environments. Avoid kinking the cable during installation, as sharp bends can alter the impedance and affect the accuracy of the transducer output. Ensure all connector interfaces are clean and fully engaged to maintain environmental sealing.
