Bently Nevada 330906-02-12-10-02-05 3300 XL NSv Probe
A 3/8-24 UNF reverse-mount proximity probe with fixed 0.2 in unthreaded section, 1.2 in case and 1.0 m lead.
Overview
330906-02-12-10-02-05 is a Bently Nevada 3300 XL NSv reverse-mount probe for close-clearance rotating-machinery measurements. The exact code retains the reverse-mount thread, fixed geometry, lead length, connector and approval selection.
It is used with the compatible NSv Proximitor Sensor and extension cable as a complete system. Gap, target material, system length and hazardous-area approval must be checked before installation.

Features
- Uses reverse mounting where normal threaded access is restricted.
- Retains a 1.0 m lead and standard ClickLoc cable option in the exact order code.
- Supports vibration, position, speed or timing measurements when paired with the matched NSv system.
- Multiple approvals are part of the suffix and must be confirmed from the delivered label.
Applications
- Close-clearance compressor and rotating-machine monitoring.
- Radial vibration, axial-position or timing-reference measurement.
- Retrofit work where a reverse-mount housing is already installed.
Lifecycle
- Confirm the Proximitor, extension cable, target material and system length before removal.
- Isolate the machine and protect the sensing tip during reverse-mount work.
- Record gap, thread engagement, cable route and approval markings at commissioning.
- Replace the full matched system if the installed components do not meet the same electrical configuration.
FAQ
What makes 330906-02-12-10-02-05 different from a standard 3300 XL probe?
Its 3300 XL NSv reverse-mount geometry uses a fixed 0.2 in unthreaded section and 1.2 in case for restricted installation access.
Which cable detail must remain matched for 330906-02-12-10-02-05?
The 1.0 m lead and 02 standard ClickLoc cable option must be combined with the approved NSv extension and Proximitor arrangement.
What target information is needed before installing 330906-02-12-10-02-05?
Confirm target material, minimum target diameter, initial gap, shaft runout and the applicable system linear range.
Can the approval suffix of 330906-02-12-10-02-05 be assumed from a similar probe?
No. Use the approval marking on every installed component and keep the complete ordering code unchanged.
What evidence should accompany a 330906-02-12-10-02-05 quotation?
Provide the removed probe label, Proximitor number, cable route, mounting drawing, target details and required hazardous-area approval.
