Bently Nevada 16925-70 Interconnect Cable | 70ft Shielded 3-Core

Global PLC Spare HUB's Insight

Engineers often face signal degradation in long-distance vibration monitoring setups due to electromagnetic interference. Using the correct shielded interconnect cable ensures signal integrity between proximity probes and monitoring systems. For example, a 70-foot run across a turbine deck requires low capacitance and robust shielding to prevent false trip signals during high-vibration events.

Product Introduction

The Bently Nevada 16925-70 interconnect cable delivers reliable signal transmission for industrial machinery protection systems. Bently Nevada engineered this cable for harsh plant environments. Global PLC Spare HUB supplies this verified component to maintain continuous operation in rotating equipment.

Comparison and Selection Guide

Engineers select specific cable lengths based on physical separation between transducers and monitors. Review the alternative length option below for your specific rack layout:

• 16925-30: 30-foot configuration for close-coupled instrument racks.
• 16925-70: 70-foot configuration for extended cable routing across large turbine foundations.

Installation Guide

Route the 16925-70 cable away from high-voltage power lines to minimize induced noise. Secure the 3-socket plug firmly to the probe connector. Fasten the terminal lugs securely to the monitor input terminals. Ground the shield drain wire at one end only to prevent ground loops.

Commissioning and Maintenance

Verify continuity across all three conductors using a digital multimeter before system power-up. Check insulation resistance between conductors and the shield regularly. Inspect the outer jacket during routine outages for signs of mechanical wear or chemical degradation.

Compatibility

The 16925-70 cable integrates seamlessly with Bently Nevada 3300 and 3500 monitoring systems. It connects standard proximity transducers directly to rack-mounted monitor channels without signal adapters.

Frequently Asked Questions

What causes high noise levels on the 16925-70 cable?

Improper grounding of the shield or routing the cable parallel to high-voltage motor cables usually causes signal noise. Ground the shield at the monitor end only.

Can field technicians cut the 16925-70 cable to a shorter length?

Shortening the cable changes the total loop capacitance, which alters calibration for proximity probe systems. Always order the exact length required for the installation.
