16925-17 Bently Nevada High-Temp Transducer Interconnect

Product Overview

The Bently Nevada 16925-17 functions as a high-integrity interconnect cable designed specifically for Bently Nevada proximity transducer systems. It provides the critical electrical link between the proximity probe and the Proximitor® sensor, ensuring the transmission of high-frequency eddy current signals without attenuation or distortion. We supply this cable as 100% Brand New original hardware, engineered to withstand the mechanical stress and electrical noise common in industrial turbine and compressor decks. The "-17" designation indicates a specific length tailored for medium-to-long distance runs within machinery protection racks.

Technical Specifications

Engineering Advantages

• Optimized Capacitance Matching: The 16925-17 maintains a strictly controlled capacitance-per-foot ratio. Because eddy current systems rely on tuned resonant circuits, this cable prevents signal phase shifts, ensuring the monitor reports accurate shaft displacement and vibration levels.

• Superior EMI/RFI Immunity: High-density braiding shields the internal conductor from electromagnetic interference generated by nearby motors, VFDs, and ignition systems. This shielding prevents "electronic noise" from being misinterpreted as machinery vibration, eliminating false trips.

• Teflon-Based Durability: The outer jacket and internal dielectrics utilize high-grade fluoropolymers. This material resists degradation from hot lubricating oils, moisture, and corrosive chemical vapors, maintaining electrical integrity where standard PVC cables would crack or short-circuit.

• Low-Loss Signal Transmission: Gold-plated or high-conductivity connector surfaces minimize contact resistance at the probe and Proximitor® junctions. This ensures that the low-millivolt signals generated by the probe tip reach the monitoring rack with zero measurable loss.

• Mechanical Strain Resilience: The 16925-17 incorporates a ruggedized internal core that resists stretching and kinking during installation through conduit or cable trays. This prevents changes in the cable’s electrical length, which could otherwise shift the system's calibration.

Installation Guidelines

When installing the 16925-17, ensure the connectors remain clean and dry. Use a torque wrench where specified to secure the miniature coaxial "ClickLoc" connectors, preventing them from loosening due to machine vibration. Always route the interconnect cable away from high-voltage power lines to further minimize noise. If the cable passes through a conduit, utilize a pulling lubricant compatible with fluoropolymer jackets to avoid skinning the outer insulation.

FAQs

• Can I cut the 16925-17 to a shorter length?

  No. You must never cut or splice Bently Nevada interconnect cables. The electrical length of the 16925-17 is factory-tuned to match the proximity system's calibration. Altering the length will cause significant measurement errors and invalidate API 670 compliance.

• Is the 16925-17 compatible with the 3300 XL series?

  The 16925 series is a versatile interconnect line. While often used with 7200 and 9000 series systems, you should verify your specific system's required total electrical length (typically 5m or 9m) to ensure the 16925-17 fits the overall calibration profile.

• How do I protect the connectors in oily environments?

  We highly recommend using Bently Nevada connector protectors or heat-shrink tubing over the junctions to prevent oil and moisture ingress, which can cause signal grounding or "dirty" data readings.

• Does this cable include armor?

  The 16925-17 is a standard shielded cable. If your application requires high mechanical protection against crushing or sharp edges, you should specify the armored version or install this cable within a flexible liquid-tight conduit.
