Frequently Asked Questions

Q: How does armored cable construction improve reliability in industrial environments?
A: Armored cables feature reinforced protective layers—typically interlocked metal or high-strength polymer—that resist crushing forces, abrasion, impact damage, and rodent intrusion. This construction extends service life 3-5x compared to standard PVC jacketed cables in demanding installations, reducing replacement frequency and maintenance costs.

Q: What is the maximum cable run length for maintaining signal integrity with proximity sensors?
A: The 12-foot 16925-12 operates within optimal proximity sensor system guidelines. For total cable runs exceeding 20 feet (including extension cables), verify system impedance matching and capacitance loading specifications. Consult Bently Nevada system documentation for specific proximitor models to ensure measurement accuracy.

Q: Can this interconnect cable be installed in hazardous area classifications?
A: When integrated into certified intrinsically safe monitoring systems, the cable supports Class I Division 2 (North America) and ATEX Zone 2 (Europe) installations. Verify complete system certification documentation including barriers, sensors, and monitoring equipment to ensure regulatory compliance.

Q: What maintenance procedures are recommended for armored interconnect cables?
A: Perform semi-annual visual inspections checking for jacket damage, connector integrity, secure terminations, and proper cable support. Conduct annual electrical testing using a megohmmeter to verify insulation resistance (minimum 100 MΩ at 500 VDC) and continuity. Document inspection results for maintenance records.

Q: Is the 16925-12 compatible with legacy 3300 series proximitor systems during system upgrades?
A: Yes, this cable maintains full backward compatibility with 3300 XL proximitor sensors while supporting newer 3500 series rack-mounted monitoring platforms. This compatibility enables phased system upgrades without complete cable infrastructure replacement, protecting capital investments.

Q: How does EMI shielding protect vibration measurement accuracy in electrically noisy facilities?
A: The comprehensive electromagnetic shielding creates a Faraday cage effect around signal conductors, blocking external electromagnetic fields from variable frequency drives, motor controllers, welding equipment, and radio transmitters. This protection maintains low-level sensor signal integrity essential for accurate vibration amplitude and phase measurements.
