30ft Armored Interconnect Cable for Industrial Vibration Monitoring Systems

The Bently Nevada 16710-30 delivers factory-certified signal integrity for critical machinery protection applications. This 30-foot armored cable assembly connects proximity sensors to monitoring racks in turbomachinery, rotating equipment, and process control environments where electromagnetic interference and mechanical hazards demand industrial-grade construction.

Designed for seamless integration with Bently Nevada 3300 XL, 3300 NSv, and 3500 series platforms, the 16710-30 eliminates field termination errors while providing dual-layer protection against EMI/RFI noise and physical damage. Pre-installed connectors and color-coded conductors enable rapid deployment in both new installations and retrofit projects.

Whether you're instrumenting steam turbines in power generation facilities, monitoring centrifugal compressors in petrochemical plants, or upgrading legacy vibration systems, this cable assembly ensures measurement accuracy and long-term reliability in the harshest industrial conditions.

Core Features & Technical Advantages

→ Dual-Layer EMI Protection
Braided tinned copper shield (95% coverage) combined with galvanized steel interlocked armor creates >90 dB shielding effectiveness, eliminating signal corruption from VFDs, motor starters, and high-voltage switchgear in electrically noisy environments.

→ Factory-Calibrated Terminations
Pre-installed BNC/TNC connectors maintain 50-ohm impedance matching across the entire 0-10 kHz vibration monitoring bandwidth, ensuring ±1% measurement accuracy required for API 670 machinery protection compliance.

→ Industrial-Grade Construction
Interlocked steel armor withstands crushing forces up to 1,200 lbs, while oil-resistant PVC jacket and moisture-sealed terminations enable reliable operation in temperatures from -40°C to +105°C.

✓ Low-Loss Signal Transmission
22 AWG high-purity copper conductors with XLPE insulation deliver <0.5 dB attenuation, preserving proximitor output signal fidelity over the full 30-foot cable length.

✓ Plug-and-Play Installation
Color-coded wiring and keyed connectors eliminate the need for specialized crimping tools, cable stripping, or continuity testing—reducing installation labor by 40% compared to field-terminated alternatives.

✓ Multi-System Compatibility
Verified interoperability with all Bently Nevada 8mm and 11mm proximity probes, accelerometers, and velocity sensors ensures drop-in replacement capability for legacy 7200 series systems.

Industrial Application Scenarios

Power Generation Turbomachinery
In steam turbine and gas turbine installations, the 16710-30 connects shaft vibration sensors to rack-mounted monitors in control rooms located 20-30 feet from bearing housings. The armored construction satisfies NEC Article 330 requirements for mechanical protection in cable tray runs through turbine decks and penetrations.

Petrochemical Rotating Equipment
Centrifugal compressor and pump monitoring systems in refineries and chemical plants require cables that resist exposure to hydrocarbon vapors, process chemicals, and high ambient temperatures. The oil-resistant jacket and sealed terminations maintain signal integrity in Class I Division 2 hazardous locations.

Legacy System Upgrades
When replacing damaged or degraded cables in existing Bently Nevada installations, the 16710-30 provides direct compatibility with 3300 series proximitors and monitors without system recalibration—minimizing downtime during planned maintenance outages.

Multi-Point Sensor Arrays
Process plants monitoring dozens of motors, fans, gearboxes, and blowers benefit from standardized 30-foot cable lengths that simplify inventory management, reduce spare parts complexity, and ensure consistent signal quality across distributed monitoring networks.

Marine and Offshore Platforms
Shipboard propulsion systems and offshore oil platform machinery operate in corrosive saltwater environments with extreme vibration and temperature cycling. The galvanized steel armor and moisture-resistant construction deliver 15+ year service life in these demanding conditions.

Technical Specifications & Selection Guide

Selection Criteria: Choose the 16710-30 when sensor-to-monitor distance ranges from 25-30 feet. For shorter runs (15-20 feet), consider the 16710-20 model to minimize cable slack and reduce installation costs. Total cable length (extension cable + interconnect cable) should not exceed 100 feet to maintain signal integrity per Bently Nevada engineering guidelines.

Extended Capabilities & Integration Options

Hazardous Area Certification
The armored construction meets mechanical protection requirements for Class I Division 2 and ATEX Zone 2 installations when installed per NEC Article 501 and IEC 60079 standards. Consult local electrical codes for specific conduit sealing and grounding requirements.

Custom Length Options
While the 16710-30 provides optimal performance for most applications, custom cable lengths from 10 to 50 feet are available through Bently Nevada's factory configuration program. Lead times for custom assemblies typically range from 4-6 weeks.

System Integration Support
Our technical team provides pre-sale consultation for complex multi-sensor installations, including cable routing optimization, grounding scheme design, and electromagnetic compatibility analysis. Post-installation support includes troubleshooting assistance and replacement cable expediting.

Frequently Asked Questions

Can I use this cable with third-party vibration monitoring systems?
The 16710-30 uses standard BNC/TNC connectors and 50-ohm coaxial construction, making it physically compatible with most industrial monitoring systems. However, optimal performance requires impedance-matched inputs and compatible signal conditioning. Verify your monitor's input specifications before ordering.

What's the maximum total cable length for proximitor applications?
Bently Nevada recommends total cable length (probe extension cable + interconnect cable) not exceed 30 meters (100 feet) to maintain measurement accuracy. For longer distances, use proximitor sensors with integrated signal conditioning or install intermediate junction boxes with active buffering.

How should the armor be grounded to prevent ground loops?
Proper installation requires single-point grounding at the monitor end only. The probe end armor must remain isolated to prevent circulating currents that introduce noise. Follow Bently Nevada installation manual guidelines for bonding and grounding in hazardous locations.

Is the cable suitable for outdoor or wet environments?
Yes, when installed in conduit or cable tray with weatherproof termination sealing. The PVC jacket provides moisture resistance, but connectors require additional environmental protection (heat-shrink boots or sealed enclosures) for direct-burial, submerged, or continuous water exposure applications.

What installation tools are required?
None—the cable arrives fully terminated and factory-tested. Simply route the cable per NEC Article 330 requirements, secure it in cable tray or conduit, and connect to sensor and monitor. Connector tightening torque specifications are provided in the included installation documentation.

Can I repair a damaged cable or replace connectors in the field?
Field repair is not recommended. The factory terminations are precision-calibrated for impedance matching and signal integrity. Damaged cables should be replaced entirely to maintain system accuracy and warranty coverage. Keep spare cables on hand for critical machinery protection applications.
