Quick Detail

Description

The Bently Nevada 84661-12 Standard Armored Interconnect Cable is a robust, high-performance cable assembly designed as the critical signal link within industrial machinery protection and vibration monitoring systems. Engineered to seamlessly connect 3300 XL series proximity probes to their corresponding Proximitor signal conditioners, this armored interconnect cable ensures the integrity of sensitive eddy current measurement signals across demanding plant environments. With a standard total length of 3 meters (9.8 feet), it provides optimal reach for typical installations, bridging the gap between sensor mounting points and monitoring cabinets. The cable features a highly reliable miniature coaxial connector system, typically of the ClickLoc style, on one end for secure probe attachment, and is prepared for field wiring on the opposite end, supporting conductors from 0.2 to 1.5 mm² (16 to 24 AWG) for easy termination at the Proximitor.

At the core of its design is a specialized triaxial or coaxial construction featuring a controlled extension cable capacitance of 55 pF/m (typical). This precise electrical characteristic is meticulously matched to the 3300 XL transducer system to minimize signal attenuation and phase distortion, preserving the accuracy of both dynamic vibration waveforms and static position (gap voltage) data. The cable assembly maintains a stable 50 Ω output resistance and exhibits minimal supply sensitivity (less than 2 mV/V), ensuring the transmitted signal remains immune to common power supply fluctuations. These attributes are maintained across a broad operating and storage temperature range of -40°C to +85°C, guaranteeing reliable performance from frigid outdoor installations to warm control room environments.

Applications

This armored cable is essential for creating robust connections in machinery protection systems for steam turbines and centrifugal compressors in power generation and oil & gas sectors. Its 3-meter length and armored construction allow it to be safely routed through cable trays and near high-vibration equipment, reliably transmitting precise shaft vibration and axial position signals from the 8 mm or 11 mm proximity probes to the monitoring rack without signal degradation or physical damage.

It serves as a key component in retrofit and upgrade projects where legacy sensor cabling needs replacement. The cable's standard electrical characteristics ensure compatibility with 3300 XL Proximitor modules, while its armored jacket provides enhanced durability over older, unarmored cables. This makes it ideal for improving system reliability in harsh industrial environments like pulp and paper mills or mining operations, where existing cabling may be prone to failure.

The cable is perfectly suited for Keyphasor (speed reference) signal transmission in rotating equipment monitoring. Its low capacitance and stable impedance ensure a clean, undistorted once-per-revolution pulse is delivered to the monitoring system, which is critical for accurate vibration phase analysis and machine balancing. The armored protection is particularly valuable in areas where the cable may be exposed to moving parts or routine maintenance activities.

Specifications

Competitive Advantage

1.Superior Mechanical Protection with Armored Construction

The integrated armored sheath provides a critical defense layer absent in standard interconnect cables. It offers exceptional resistance to crushing forces, abrasion from sharp edges, accidental impact from tools or dropped objects, and rodent damage. This built-in durability drastically reduces the risk of cable failure due to physical damage, minimizing unplanned downtime and maintenance costs in rugged industrial environments.

2.Precision-Engineered for Guaranteed Signal Fidelity

Unlike generic coaxial cables, the 84661-12 is electrically characterized specifically for Bently Nevada transducer systems. Its specified 55 pF/m capacitance and 50 Ω impedance are optimized to work with 3300 XL probes and Proximitors, ensuring minimal signal loss and preserving system calibration and linearity. This guarantees accurate vibration and position measurement data reaches the monitoring system without compromise.

3.Certified Reliability for Global Industrial Deployment

The cable carries multiple international agency approvals (such as CSA, ATEX, IECEx), confirming its compliance with stringent safety and performance standards for use in various industrial and potentially hazardous locations. This multi-certification simplifies procurement for global projects, ensures regulatory compliance, and provides engineers with confidence in the product's suitability for critical applications worldwide.
