General Information

Core Description

The 16710-85 is a Bently Nevada high-integrity 3-conductor shielded armored interconnect cable measuring 85 feet in length. Fully compatible with a 3-pin MIL-C-5015 sensor receptacle, this unit works seamlessly with casing acceleration transducers to deliver stainless steel mechanical armoring, stable signal transmission over long distances, and reliable machinery protection wiring loops.

Specific Application

• Gear Mesh and Casing Vibration Monitoring: Connecting high-frequency casing accelerometers mounted on heavy industrial gearboxes and multi-stage pumps to remote monitoring racks.
• Severe Mechanical Wear Cable Routing: Shielding signal paths from physical abrasions, sharp casing edges, or fly-debris using a flexible stainless steel outer armor layer.
• High-Noise Industrial Plant Environments: Reducing electrical noise interference across an 85-foot route using a 22 AWG shielded triad wire topology.

Ordering Information

System Compatibility

• Transducers: Integrates directly with the Bently Nevada 330400, 330425, 330500, and 330525 accelerometer and velocity sensor families.
• Sensor Connector: Terminates at the sensor end via a rugged 3-socket plug matching standard 3-pin MIL-C-5015 receptacles.
• Terminal Racks: Ends at the terminal side with ready-to-wire terminal lugs for easy junction box landings.

Substitute Options & Technical Differences

• Alternative Non-Armored Model: Bently Nevada 3-Conductor Shielded Interconnect Cable (Part Number: 16925-85).
• Key Differences:

• Mechanical Protection: The 16710-85 features a rugged stainless steel outer armor jacket over the triaxial core wires. The 16925-85 uses a bare, non-armored design meant for clean protective conduits.
• Cable Flexibility: Non-armored cables offer a smaller physical routing profile and high flexibility, while the armored model trades tight bend radiuses for heavy physical smash and cut resistance.

Installation & Troubleshooting FAQ

Q1: What wire gauge configuration and structural material are used inside the 16710 cable line?
A: The internal core utilizes a 22 AWG (0.5 mm²) 3-conductor twisted, shielded wiring layout wrapped in an outer stainless steel protective armor shell.

Q2: Can I route this 85-foot armored cable directly through wet or 100% condensing environments?
A: Yes, for the cable jacket itself. However, the IP68 rating applies strictly to the hermetically sealed sensor body. Always use sealed conduit fittings or boot sleeves at the plug end to prevent water from bridging the 3-socket termination.

Q3: My acceleration reading is showing high noise or erratic spikes. How do I test cable grounding?
A: The sensor case is electrically isolated from the internal circuitry. Check that the cable shield drain wire is landed to an isolated instrument ground at the monitor rack, and verify that it is not touching the machine casing.

Q4: What is the maximum allowable cable length for this specific transducer system?
A: You can extend your field interconnect runs up to a maximum length of 305 meters (1,000 feet) without suffering any signal degradation or frequency response drop-offs.

Q5: What mechanical steps ensure a secure and stable connection to the 330400 accelerometer?
A: Align the internal keyways of the 3-socket plug with the sensor's MIL-C-5015 receptacle. Hand-tighten the threaded coupling ring onto the accelerometer housing until it locks securely against the hex base.
