Core Features & Technical Advantages

Low-Noise Coaxial Design
Precision 75Ω coaxial construction with multi-layer shielding minimizes electromagnetic interference (EMI) and radio frequency interference (RFI), ensuring clean signal transmission even in electrically noisy industrial environments with VFDs, motors, and high-voltage equipment nearby.

API 670 Compliance & Safety Certification
Meets API Standard 670 requirements for machinery protection systems, making it suitable for safety instrumented systems (SIS) and critical turbomachinery applications in oil & gas, power generation, and process industries where regulatory compliance is mandatory.

Extended Transmission Distance
8.5-meter (approximately 28 feet) length provides installation flexibility for proximity probe-to-proximitor connections, allowing sensor placement optimization while maintaining signal integrity across the entire measurement chain without additional signal conditioning.

Rugged BNC Connector Terminations
Industrial-grade BNC connectors ensure secure, vibration-resistant connections with quick-disconnect capability for maintenance efficiency. Gold-plated contacts resist corrosion in humid or chemically aggressive atmospheres, extending service life and reducing connection failures.

Temperature & Environmental Resilience
Engineered for continuous operation in demanding conditions including temperature extremes, moisture exposure, chemical vapors, and mechanical stress. Cable jacket materials resist oil, coolant, and common industrial solvents encountered in turbomachinery installations.

Seamless 3300 XL System Integration
Factory-tested compatibility with Bently Nevada 3300 XL proximitors, extension cables, and proximity probes ensures plug-and-play installation without impedance mismatches or signal reflection issues that can compromise measurement accuracy.

Typical Application Scenarios

This extension cable is engineered for vibration monitoring systems requiring reliable signal transmission, continuous operation, and regulatory compliance, particularly in:

Steam & Gas Turbine Monitoring
Connects radial vibration probes on turbine bearing housings to proximitor modules in control rooms, enabling real-time shaft displacement monitoring for trip protection and condition-based maintenance in power generation facilities.

Centrifugal Compressor Protection Systems
Provides signal extension for axial position and radial vibration sensors on multi-stage compressors in natural gas processing, petrochemical plants, and air separation units where equipment failures result in significant production losses and safety risks.

Large Motor & Generator Bearing Monitoring
Facilitates proximity probe installation on critical rotating equipment in steel mills, mining operations, and manufacturing plants, allowing early detection of bearing wear, shaft misalignment, and rotor imbalance before catastrophic failure occurs.

Pump & Fan Vibration Analysis
Extends sensor reach for boiler feed pumps, cooling tower fans, and process pumps in refineries, chemical plants, and water treatment facilities, supporting predictive maintenance programs and reducing unplanned downtime.

Marine Propulsion & Auxiliary Systems
Enables vibration monitoring on ship propulsion turbines, diesel generators, and auxiliary machinery where space constraints and harsh marine environments demand robust, corrosion-resistant cabling solutions.

Technical Specifications & Selection Guide

To ensure optimal system performance and compatibility, please review the following specifications:

Selection Considerations: When specifying extension cables for your vibration monitoring system, consider total cable run length (probe to proximitor), environmental conditions (temperature, chemical exposure, moisture), mounting constraints, and system architecture. For installations requiring different lengths, Bently Nevada offers extension cables in multiple standard lengths. Our application engineers can assist with cable length calculations, system layout optimization, and compliance verification for your specific installation.

Frequently Asked Questions (FAQ)

Q: How does the Bently Nevada 330130-085-10-00 extension cable integrate with existing 3300 XL proximity monitoring systems?
A: The cable features standard BNC connectors on both ends for direct connection between 3300 XL proximity probes and proximitor modules. Simply connect one end to the probe cable and the other to the proximitor input maintaining proper grounding and shield continuity. No special adapters or signal conditioning required.

Q: What is the maximum number of extension cables that can be connected in series for a single measurement channel?
A: While multiple extension cables can be cascaded, total system cable length (probe cable + extension cables + proximitor cable) should not exceed manufacturer recommendations typically 9-12 meters depending on probe type and application. Consult API 670 guidelines and Bently Nevada system documentation for your specific configuration to ensure measurement accuracy and compliance.

Q: What signal integrity performance can be expected with this 8.5-meter extension cable in electrically noisy environments?
A: The low-noise coaxial design with >90% shield coverage provides excellent EMI/RFI rejection. In properly grounded installations, signal-to-noise ratio degradation is typically <2% even near VFDs, motors, and high-voltage switchgear. Proper cable routing away from power cables and maintaining single-point grounding further optimizes performance.

Q: Are there specific environmental conditions or installation requirements for this extension cable?
A: The cable operates reliably from -40°C to +85°C with oil and chemical-resistant jacketing suitable for most industrial environments. Avoid sharp bend radii (minimum 10x cable diameter), protect from mechanical damage in high-traffic areas, and ensure BNC connectors are fully seated and secured. Indoor and outdoor installations supported with appropriate cable management and protection.

Q: Can this cable be used for remote monitoring applications with data transmission to control rooms or SCADA systems?
A: Yes, the cable extends the proximity probe signal to the proximitor module which converts the high-frequency probe signal to industry-standard 4-20mA or -10 to +10VDC outputs. These proximitor outputs can then be transmitted over long distances to DCS, PLC, or SCADA systems using standard industrial wiring practices. The extension cable handles the critical probe-to-proximitor connection.

Q: What documentation and certifications are provided to support API 670 compliance verification during project commissioning?
A: Each cable includes a certificate of conformance documenting API 670 compliance, electrical specifications (impedance, capacitance, shield effectiveness), and traceability information. Complete system compliance documentation including installation guidelines, test procedures, and as-built drawings can be provided to support SIS validation and regulatory audits.
