Machine-side sensing position
The flexible probe body follows the documented installed route while the sensing tip remains fixed toward the conductive target, keeping machine geometry separate from the downstream electronics.

Product Description
Bently Nevada 129716-XXX-032-90-05 MOD:166797-0111 is a modified flexible proximity probe associated with the 3300 XL 8 mm proximity transducer system. The probe forms the target-facing element of the eddy-current measurement chain, while the matched extension cable and Proximitor Sensor provide excitation and convert the probe response into the voltage received by the monitor.
The complete identity Bently Nevada 129716-XXX-032-90-05 MOD:166797-0111 must be retained because the public 3300 XL ordering table does not resolve the XXX field or the modification-specific meanings of every suffix. The visible 032, 90 and 05 fields therefore remain part of the requested configuration instead of being replaced with meanings borrowed from a standard probe code.
When Bently Nevada 129716-XXX-032-90-05 MOD:166797-0111 is installed, the modified flexible probe geometry, connector path and total electrical length must be checked against the nameplate and modification drawing. Gap setting is completed only after the compatible 3300 XL 8 mm electronics are connected, because the probe by itself does not produce the calibrated monitor output.

System Integration
Bently Nevada 129716-XXX-032-90-05 MOD:166797-0111 occupies the machine end of a 3300 XL 8 mm chain, where its flexible mechanical path, matched cable length and external Proximitor Sensor work as one measurement system.
Matched cable path
The unconditioned probe response travels through the documented extension cable to the compatible Proximitor Sensor; the probe and extension cable together must preserve the installed total electrical length.
Conditioned monitor handoff
The Proximitor Sensor excites the probe path and converts its impedance change into the proportional voltage sent to the monitoring channel, so the monitor receives a conditioned signal rather than the raw probe response.

Key Features
Bently Nevada 129716-XXX-032-90-05 MOD:166797-0111 combines flexible probe construction with the non-contact response and matched-component behavior of the 3300 XL 8 mm transducer family.
Flexible mechanical construction
The flexible section lets the probe path follow the documented machine route while the sensing tip remains positioned at the conductive target.
Non-contact eddy-current sensing
Target movement changes the probe response without mechanical contact; the matched electronics convert that change across the 2.0 mm system measuring range.
Interchangeable 3300 XL components
Within the documented 3300 XL 8 mm family, compatible probes, extension cables and Proximitor Sensors share the 7.87 V/mm system response without individual bench matching.

Common Questions
01Why must the XXX field be retained on Bently Nevada 129716-XXX-032-90-05 MOD:166797-0111?
The XXX field on Bently Nevada 129716-XXX-032-90-05 MOD:166797-0111 is not resolved by the public standard ordering table. Keep it with MOD 166797-0111 and confirm the exact execution from the nameplate or modification drawing.
02Can Bently Nevada 129716-XXX-032-90-05 MOD:166797-0111 be replaced by a standard 3300 XL 8 mm probe?
Do not assume that a standard probe replaces Bently Nevada 129716-XXX-032-90-05 MOD:166797-0111. The flexible mechanical execution, cable path, full suffix string and modification reference must match the installed record.
03What should be measured before removing Bently Nevada 129716-XXX-032-90-05 MOD:166797-0111?
Before removing Bently Nevada 129716-XXX-032-90-05 MOD:166797-0111, record the exposed reach, mounting reference, flexible-section route, connector position and conditioned gap voltage.
04Why is connector fit insufficient for Bently Nevada 129716-XXX-032-90-05 MOD:166797-0111?
A connector can fit Bently Nevada 129716-XXX-032-90-05 MOD:166797-0111 while the probe family or total electrical length is wrong. Verify the probe, extension cable and Proximitor Sensor as one calibrated chain.
05How is Bently Nevada 129716-XXX-032-90-05 MOD:166797-0111 checked after installation?
After installing Bently Nevada 129716-XXX-032-90-05 MOD:166797-0111, confirm cable continuity, Proximitor supply, static gap voltage and monitor response before restoring the channel to service.
06What if the 032 or 90 field on Bently Nevada 129716-XXX-032-90-05 MOD:166797-0111 conflicts with a site record?
Stop the replacement check if Bently Nevada 129716-XXX-032-90-05 MOD:166797-0111 conflicts with the site record. Resolve the complete nameplate and modification drawing instead of reinterpreting those fields from another probe family.
