86691-00750-0435-15 identifies a configured Bently Nevada legacy vibration probe assembly for an installed non-contact shaft-measurement loop. The complete code must remain intact because its mechanical and electrical details are configuration-specific.

A compatible measurement chain includes the installed probe, extension cable and signal conditioner. Tip size, case style, lead length, connector, total system length and target geometry must be checked together.

• Provides non-contact observation of a conductive shaft target in a compatible proximity measurement loop.
• Uses a configured probe construction whose full order code identifies the installed assembly.
• Forms one electrical system with the matching extension cable and signal conditioner.
• Supports machinery measurements such as shaft vibration or position when installed and configured for that duty.
• Keeps 86691-00750-0435-15 separate from probes that may look similar but use different lengths, cases or connectors.

• Legacy shaft radial-vibration measurement.
• Shaft axial-position or thrust-position monitoring.
• Rotating-equipment condition and protection loops.
• Maintenance replacement where the original probe configuration must be preserved.
• Installed systems requiring a complete probe-chain compatibility review.

• Retain the full 86691-00750-0435-15 configuration when documenting the installed probe.
• Measure the installed case and lead arrangement before removal.
• Record extension-cable and signal-conditioner part numbers as one system.
• Set the mechanical gap using the applicable system procedure.
• Validate static voltage, dynamic response and alarm operation after installation.
