Product Overview

The Bently Nevada 16710-32 Shielded Two-Wire Interconnect Cable maintains an absolute low-noise, high-fidelity analog telemetry path within critical machinery casing vibration monitoring loops. This professional-grade cable establishes the essential electrical linkage between a local industrial housing accelerometer (such as the Bently Nevada 330525 or 23732 series acceleration transducers) and a remote field junction box or centralized multi-channel monitor rack.

Plant instrumentation specialists deploy this 32-foot high-performance interconnect line across high-demand industrial processing sectors, including oil gas refineries, thermal power generation plants, and chemical manufacturing complexes. The precision-engineered internal dielectric core limits signal damping over extended structural runs, allowing the system to transmit micro-voltage AC acceleration telemetry cleanly. This real-time dynamic data feeds directly into your safety shutdown loops and automated DCS interlocks, empowering the system to trip heavy machinery instantly before structural fatigue or severe rotor imbalance triggers a catastrophic failure.

Structural Assembly & Suffix Decoding Blueprint

16710 [Two-Wire Shielded Interconnect Baseline]

Designates the product family profile as a 2-conductor shielded twisted-pair signal cable assembly, terminated on the transducer end with a heavy-duty, splash-proof female circular socket connector.

-32 [Physical Length Metric]

Specifies a strict physical deployment length of 32 feet (9.75 meters), providing an extended mechanical reach that spans directly from the machine bearing housing to local structural conduit runs without requiring inline splices.

Fluoropolymer Outer Insulation Jacket

Utilizes a premium extruded fluorinated ethylene propylene (FEP) outer compound layer that resists chemical breakdown while maintaining a low dielectric constant across varying industrial operational cycles.

High-Density Aluminum Foil Braided Shield

Features a full-coverage aluminum-polyester electrostatic shield backed by a continuous tinned copper drain line to ground out environmental electromagnetic interference (EMI) and prevent cross-talk from adjacent power conductors.

On-Site Deployment & Grounding Protocols

Field wiring technicians must maintain a strict minimum bend radius of 38.1 mm (1.5 inches) across the unarmored 32-foot fluoropolymer run to prevent stretching the internal conductor structures or tearing the foil shield layout. Prior to pulling the cable through rigid field conduit networks, check that the conduit interior remains dry and free of jagged mechanical burrs. Thread the heavy-duty 2-pin circular female MIL connector tightly onto the accelerometer base hub, ensuring the internal elastomeric gasket seats fully to exclude moisture and contaminants.

Isolate the shield grounding layout perfectly to prevent problematic ground loops from injecting electrical noise into the high-frequency vibration tracking path. Connect the tinned copper drain wire at the blunt-cut terminal end directly to the dedicated instrument ground bar inside the local junction box. Leave the shield wire floating and cut back flush at the sensor end of the loop, using a heat-shrink sleeve over the cable transition point to maintain absolute isolation from the machine frame.

Extreme Durability & Process Infrastructure Integration

The chemical-resistant FEP outer jacket of the 16710-32 interconnect cable prevents structural breakdown when subjected to continuous exposure to industrial fluid contaminants, including hot synthetic lube oils, caustic ammonia fumes, or low-pressure steam leaks. This high durability keeps insulation resistance values high across multi-year operating campaigns, preventing signal attenuation over the 32-foot run.

The low-loss twisted-pair line streams dynamic casing vibration profiles into a Bently Nevada 3500/42M or 3500/40M monitor module for real-time processing. The monitor splits the processed tracking values out to your plant-wide Honeywell Experion PKS or Siemens S7 PLC architecture via automated Modbus TCP or dedicated 4-20 mA analog output cards. This setup supplies your control room with simultaneous access to high-velocity casing vibration safety trips and deep predictive machine health trending.

Transducer Loop Field Troubleshooting

Q1: Can I deploy this 16710-32 cable to route signals from a 3300 XL eddy current proximity probe?

A1: No. This cable features a 2-conductor twisted-pair layout terminated with a large 2-pin circular MIL connector, designed specifically for casing accelerometers and velocity sensors. Proximity probes use high-frequency coaxial lines terminated with miniature ClickLoc connectors to manage specific loop impedance. Mixing these cable types will cause immediate physical incompatibility and loop failure.

Q2: What specific hazard does connecting the shield drain wire to ground at both ends introduce?

A2: Grounding the shield drain wire at both ends creates an electrical loop that permits stray currents to flow through the shield due to minor voltage potential differences between the machine frame and the control panel. These currents generate electromagnetic fields that inject severe electrical noise into the analog vibration telemetry, resulting in false spikes or monitor tracking errors.

Q3: What field action is required if the 3500 protection rack triggers a constant "Not OK" status for this channel?

A3: A constant "Not OK" status usually points to an open or short circuit along the transducer loop. Disconnect the 2-pin MIL connector at the sensor head and check for fluid contamination or loose mating pins. Use a digital multimeter to verify the continuity of each internal wire conductor from the control room terminal strip out to the sensor plug.

Q4: Does this unarmored FEP cable design require separate protective conduit on an open plant floor?

A4: Yes. Although the FEP outer insulation jacket provides excellent chemical resistance against hot oils and corrosive atmospheres, it lacks the structural toughness to resist severe mechanical crushing or sharp cuts. For open plant floor tracks or areas with heavy foot traffic, route the unarmored line inside grounded, flexible or rigid steel conduits to prevent mechanical destruction.
