Industrial Application Environments

Power Generation Facilities
In combined-cycle plants and cogeneration facilities, the 16710-35 connects bearing vibration probes on steam turbines, gas turbines, and generator sets to centralized monitoring systems. The armored construction survives the harsh conditions near boiler feedwater pumps and condensate systems where cable damage from maintenance activities is common. Typical installations monitor journal bearings, thrust positions, and shaft vibration on units ranging from 50 MW to 500+ MW capacity.

Petrochemical Processing Plants
Refinery applications demand cables that withstand exposure to hydrocarbon vapors, temperature cycling, and mechanical stress from piping vibration. Deploy the 16710-35 on centrifugal compressors handling ethylene, propylene, and other process gases where unplanned shutdowns cost $50,000+ per hour. The cable's chemical-resistant insulation and sealed armor prevent contamination-related failures in sour gas and corrosive environments.

Pipeline Compression Stations
Natural gas transmission facilities utilize this cable to monitor reciprocating and centrifugal compressors in remote, unmanned locations. The extended temperature rating handles outdoor installations from Canadian winters to Middle Eastern summers, while the armor protects against rodent damage and weather exposure that plague standard instrumentation cables.

Pulp & Paper Mills
Connect vibration sensors on paper machine dryer sections, refiners, and stock pumps where high humidity, chemical exposure, and mechanical hazards create challenging cable environments. The 16710-35's robust construction reduces replacement frequency in these demanding 24/7 continuous process operations.

Steel Manufacturing
Monitor rolling mill drives, blast furnace blowers, and continuous casters where extreme temperatures, heavy equipment traffic, and electromagnetic fields from induction heating systems challenge conventional cables. The armored design survives the physical abuse common in primary metals production.

Technical Specifications & Selection Criteria

Selection Guidelines: Choose the 16710-35 when probe-to-monitor distance falls between 25-40 feet and installation environment presents mechanical hazards or high EMI levels. For shorter runs (under 20 feet), consider non-armored alternatives to reduce cost. For distances exceeding 40 feet, evaluate system capacitance limits and consider proximitor-style sensors with local signal conditioning. Always verify total system cable length (probe cable + interconnect cable) remains within 3300 series specifications—typically 100 feet maximum for standard proximity probes.

Advanced Integration & System Architecture

Modern condition monitoring programs integrate vibration, temperature, and process parameters into unified asset health platforms. The 16710-35 serves as a critical link in these multi-parameter systems, connecting field sensors to rack-mounted monitoring hardware that feeds data to SCADA, DCS, and predictive maintenance software.

Multi-Channel Monitoring Arrays: When instrumenting machines with 8+ measurement points, maintain cable organization by color-coding armor jackets or applying heat-shrink labels at both terminations. Document cable routing in as-built drawings to facilitate future troubleshooting and expansion.

Wireless Gateway Integration: Pair armored interconnect cables with wireless vibration transmitters to create hybrid monitoring architectures—use cables for critical, high-speed measurements while deploying wireless sensors on secondary equipment to optimize total cost of ownership.

Redundant Monitoring Configurations: Safety-critical applications in nuclear, aerospace, and offshore platforms often require redundant vibration channels. Install duplicate 16710-35 cables in separate cable trays to ensure physical and electrical independence between primary and backup monitoring paths.

Installation Standards & Best Practices

Proper installation directly impacts measurement reliability and cable service life. Route the 16710-35 through dedicated instrumentation cable trays, maintaining minimum 12-inch separation from AC power cables rated above 480V. Where crossing power cables is unavoidable, cross at 90-degree angles to minimize inductive coupling.

Support cables at maximum 3-foot intervals using plastic cable ties or cushioned clamps—avoid metal clamps that compress the armor and create ground loops. When transitioning from cable tray to conduit, use strain relief fittings to prevent armor damage from vibration and thermal expansion.

Terminate shield connections at the monitor end only (single-point grounding) to prevent ground loops that introduce 60 Hz noise. Verify shield continuity with a multimeter before energizing the system. For outdoor or wet locations, apply dielectric grease to connectors and install drip loops to prevent water ingress.

Commissioning Checklist:

• Verify cable routing avoids sharp bends (minimum 10× diameter radius)
• Confirm shield grounding at monitor chassis only
• Test insulation resistance (≥100 MΩ at 500 VDC)
• Measure cable capacitance and compare to system specifications
• Document cable identification, routing, and termination points
• Perform baseline vibration measurements and compare to acceptance criteria

Frequently Asked Questions

What is the maximum total cable length for 3300 series proximity probe systems?
Combined probe cable and interconnect cable length should not exceed 30 meters (100 feet) to maintain system accuracy. Longer distances require proximitor-style sensors with integral signal conditioning or barrier-mounted proximitors that reduce interconnect cable length.

Can I use the 16710-35 with non-Bently Nevada monitoring equipment?
While physically compatible with standard BNC connectors, electrical compatibility depends on the monitor's input impedance and sensitivity. Consult your monitor manufacturer's specifications for cable capacitance limits and connector pinout requirements before cross-platform use.

How do I identify cable damage that requires replacement?
Inspect for visible armor deformation, jacket cuts exposing conductors, or connector damage. Electrical testing should reveal insulation resistance below 100 MΩ or capacitance exceeding specifications by more than 10%. Any physical damage to armor or jacket warrants replacement to ensure measurement integrity.

Is the armor electrically isolated from the signal shield?
Yes, the metal armor is electrically isolated from the internal braided shield. This design prevents ground loops while providing mechanical protection. Never use the armor as a signal ground or current-carrying conductor.

What environmental factors affect cable service life?
Primary degradation mechanisms include UV exposure (outdoor installations), chemical attack from process fluids, thermal cycling stress, and mechanical fatigue from vibration. Proper routing in cable tray or conduit, chemical compatibility verification, and strain relief at terminations maximize service life—typically 10+ years in properly designed installations.

Can I repair damaged sections or must I replace the entire cable?
Field repairs compromise both mechanical protection and electrical performance. Replace damaged cables rather than attempting splices or armor repairs. Maintain spare cables for critical applications to minimize downtime during unplanned replacements.
