Information
- Bently Nevada 129716-XXX-032-90-05 MOD:166797-0111 requires a replacement plan that preserves both the sensing location and the complete measuring chain. Record the installed gap, target and cable arrangement before disturbing the existing unit.
System family: 3300 XL 8 mm (base design)
Case thread: 3/8-24 (base design)
Modification marking: 166797-0111
Treat the base design and the supplied modification separately. Match the actual geometry, cable arrangement and operating conditions to the controlled installation before release.

Bently Nevada 129716-XXX-032-90-05 MOD:166797-0111 installation guide
Prepared by Apter Power - PDF, 5 pages. Identity checks, measuring-chain matching, installation review and response verification.
Application scope: The following describe proximity-system duties. Select the actual duty and compatibility for the complete order code and MOD configuration before installation.
-
Shaft-relative vibration
A matched proximity channel measures shaft motion relative to the probe mounting. Preserve the target area, mounting rigidity and complete probe-to-monitor chain when replacing this modified unit. -
Axial position monitoring
Use the approved thrust-target arrangement and channel setup for axial position measurement. Match installed probe geometry, operating gap and permitted shaft travel before commissioning. -
Rotating-machine condition monitoring
Proximity measurements support fluid-film bearing machinery such as turbines and compressors. Select the channel for the actual machine and measurement duty; a common probe family alone does not establish interchangeability. -
Phase and speed reference
A compatible proximity channel can observe a suitable shaft feature for phase or speed reference. Verify target geometry, signal response and receiving equipment; overspeed protection requires its own approved system assessment.
Record 129716-XXX-032-90-05 and MOD:166797-0111 together. Match the supplied marking and controlled configuration before removing the existing probe.
Compare the actual tip, case, thread engagement and lead arrangement with the installed unit. The 129716 base design uses an 8 mm tip and 3/8-24 thread; apply the modification drawing to the supplied version.
Check the probe, extension cable if used, Proximitor sensor and monitoring channel as one arrangement. Do not connect the probe directly to an assumed DC power supply or treat system output as a standalone probe rating.
Avoid probe-tip contact with the shaft. Keep the sensing area free of unintended surrounding metal, support the flexible lead and protect connectors against contamination and moisture.
Use the applicable installation and site procedures to check gap, target material, channel polarity and response. Retain the approved calibration and alarm configuration; do not derive electrical length from packaging dimensions.
Use the actual product marking and approved configuration to confirm temperature, sealing and hazardous-area requirements. A base-family approval option does not establish the certification of every modified assembly.

Technical notes
Base-design relationship: 129716 is the flexible-probe base reference. The supplied XXX-032-90-05 suffix and MOD:166797-0111 remain part of the complete product identity.
Measuring-chain verification: Confirm the actual probe geometry, cable arrangement, target and signal-conditioning hardware together. Do not transfer a standard-system rating to this modified unit without configuration confirmation.

FAQ View All FAQ
-
What does the 129716 base reference identify in 129716-XXX-032-90-05 MOD:166797-0111?The base reference identifies a 3300 XL 8 mm flexible proximity probe with a 3/8-24 case thread. Keep that base-design information separate from the supplied suffix and modification configuration.
-
How does 129716-XXX-032-90-05 MOD:166797-0111 participate in a measurement channel?The probe forms the sensing end of a matched eddy-current proximity system. The associated cable arrangement and Proximitor sensor provide the measuring chain used by the monitoring equipment; a probe alone is not a complete powered measurement system.
-
Why must the MOD marking be retained when replacing 129716-XXX-032-90-05 MOD:166797-0111?The MOD marking is part of the supplied identity. Match it together with the full order code and physical configuration; sharing the 129716 base number does not establish the same mechanical or electrical arrangement.
-
Can the 90 segment in 129716-XXX-032-90-05 MOD:166797-0111 be used to select a cable length?Use the controlled configuration and actual cable markings to select the electrical arrangement. Do not apply another probe ordering table to this modified code or derive an electrical length from the shipping dimensions.
-
Which target and mounting checks matter for 129716-XXX-032-90-05 MOD:166797-0111?Check the conductive target material, surface condition, probe operating gap, rigid mounting and clearance from surrounding metal. Compare the actual geometry with the approved installation before checking channel response.
-
Is 129716-XXX-032-90-05 MOD:166797-0111 itself a Proximitor sensor?No. The 129716 base design is a proximity probe. Keep the probe identity separate from the signal-conditioning Proximitor sensor and verify the correct companion components for the installed channel.
-
Which photos and documents should be requested for 129716-XXX-032-90-05 MOD:166797-0111?Request clear full-model and MOD-marking photos, probe-tip and connector views, and the applicable configuration drawing or unit records. Confirm the offered condition, included items, accompanying documents and warranty terms in the quotation.
-
How should quantity and dispatch be confirmed for 129716-XXX-032-90-05 MOD:166797-0111?State the required quantity and complete MOD marking when requesting a quotation. Confirm available quantity, dispatch date and when the lead time starts in writing; transport-service wording is not a stock commitment.
