Bently Nevada 16710 Series

Bently Nevada 16710-12 Interconnect Cable The Bently Nevada 16710-12, also cataloged as the 16710 Interconnect Cable, operates as a dedicated hardware component for transmitting raw vibration signals from accelerometers to monitoring system terminals within Bently Nevada TSI networks. Suffix Breakdown & Model Matrix Suffix Definition Value 16710 Base Model Armored 3-Conductor Interconnect Cable -12 Length Option 12 ft (3.6 m) Hardware Specifications Parameter Specification Model Brand Bently Nevada Origin U.S.A Weight Approx. 0.5 kg (estimated for 12 ft armored config) Dimensions 12 ft Length x 0.25 in Outer Diameter Operating Temp -40 degC to +120 degC (Typical Fluoropolymer Rating) Power Consumption Passive Component (No Active Power Draw) Conductor Gauge 22 AWG (0.5 mm2) Shielding 100% Foil Shield with Drain Wire Armor Type Interlocking Stainless Steel Eddy-Current Probe Scaling and Signal Integrity The 16710 series facilitates precise eddy-current probe scaling by maintaining consistent capacitance and impedance characteristics required for gap voltage validation. The 22 AWG conductors are optimized to support the -10 VDC target bias voltages typical in proximity probe systems. The aluminum foil shielding suppresses crosstalk between adjacent signal pairs in high-density routing trays, ensuring that rotor dynamics data remains free from EMI-induced noise floor elevation. Frequently Asked Questions Q: Does the 16710-12 support hot-swapping while the monitoring module is powered? A: No. Although the cable is passive, disconnecting the 3-socket plug while the system is energized can cause transient voltage spikes on the monitor input. Power down the associated 3500/3300 module before removal. Q: What is the maximum allowable bending radius for the armored jacket? A: Maintain a minimum bend radius of 10 times the cable diameter (approx. 2.5 inches) to prevent deformation of the interlocking stainless steel armor and subsequent shield compromise. Q: Is the cable compatible with 4-20 mA loop-powered transmitters? A: No. This is a 3-conductor passive interconnect for dynamic signal transmission (AC coupled). It is not rated for 2-wire loop power distribution. Field Installation Guidelines Grounding: Terminate the drain wire and foil shield at the monitor end only (single-point ground) to prevent ground loops. Do not allow the shield to contact the stainless steel armor. Routing: Secure the cable using non-metallic clamps. Avoid routing parallel to high-voltage power cables; maintain a minimum separation of 12 inches. Torque: When connecting the terminal lugs, apply 8-10 in-lbs of torque to the terminal block screws to ensure gas-tight connections. Armor Termination: Ensure the stainless steel armor is trimmed cleanly without leaving sharp edges that could puncture the inner insulation.

Bently Nevada 16710-08 Armored Interconnect Cable Configured for vibration signal transmission in Bently Nevada 3500 and 3300 series machinery protection systems, the Bently Nevada 16710-08 (base model 16710) provides direct physical and electrical execution between accelerometers and monitoring racks. It carries conditioned dynamic signals from transducers to input modules without intermediate conversion. Hardware Specifications Parameter Specification Brand Bently Nevada Model 16710-08 Origin United States Weight 0.824 kg Dimensions 2.4 m length Operating Temp -40 degC to 85 degC Power Consumption Passive component; no power draw Conductor Count 3 Wire Gauge 22 AWG (0.5 mm²) Shielding Foil and braid Insulation Material PVC Operating Voltage 600 V Current Rating 10 A Eddy-Current Probe Scaling and Gap Voltage Validation The 16710-08 supports eddy-current probe scaling by preserving linear signal amplitude over the full transducer operating range. When interfaced with proximity probes, it maintains stable gap voltage validation targets near -10 VDC, ensuring rotor dynamics measurements remain consistent under varying shaft displacement. Full shielding suppresses cross-talk between adjacent signal pairs in high-density machinery monitoring cabinets. Frequently Asked Questions Q: Can the 16710-08 be hot-swapped while the monitoring system is powered? A: No. Disconnect power from the associated monitoring module before connecting or disconnecting the cable to prevent transient surges. Q: Is the armor electrically bonded to the shield? A: Yes. The stainless-steel armor is bonded to the overall shield to ensure continuous EMI protection and ground reference integrity. Q: What is the maximum continuous current rating for signal conductors? A: Conductors are rated for up to 10 A, though typical vibration signal currents are well below this limit. Field Installation Guidelines Route the cable separately from high-voltage power conductors to minimize inductive coupling. Maintain minimum bend radius of 10× cable diameter. Terminate the shield at the monitoring rack end using the designated grounding point; do not ground at the transducer end to avoid ground loops. Verify connector seating by applying slight axial force after locking the 3-socket plug. Inspect armor continuity during annual preventive maintenance.
