Bently Nevada 330908-21-35-10-02-00 NSv Proximity Probe
A 3/8-24 NSv probe with a 2.1 in unthreaded section, 3.5 in case and 1.0 m standard cable.
Product Identification
330908-21-35-10-02-00 is a 3300 XL NSv proximity probe with a 3/8-24 UNF case and no armor. The order code defines the mechanical reach and cable termination required for a constrained rotating-machinery measurement point.
This probe is one part of a calibrated NSv transducer system and must be matched with the correct extension cable and Proximitor Sensor system length.

Functions
- Measures static position and dynamic vibration without mechanical contact.
- Fits applications where a larger probe body is acceptable but side-view clearance remains limited.
- Supports compatible speed, zero-speed and phase-reference measurements.
- Connects through the NSv cable system to the selected Proximitor Sensor.
Applications
- Compressor shaft vibration
- Axial position measurement
- Speed and Keyphasor measurement in restricted spaces
Lifecycle
- Manage probe, cable and sensor as one transducer system.
- Do not mix NSv components with standard 8 mm probe-system parts.
- Replace degraded components rather than recalibrating around a changed response.
FAQ
What mechanical data should be checked for 330908-21-35-10-02-00?
Confirm the 3/8-24 thread, 2.1 in unthreaded reach, 3.5 in case clearance and connector access against the machine drawing.
Can 330908-21-35-10-02-00 be connected to any Bently Nevada Proximitor?
No. It must be used in a compatible 3300 XL NSv system with the correct extension cable and total length.
How should the unarmored cable on 330908-21-35-10-02-00 be protected?
Route it away from sharp edges, hot surfaces, oil damage and excessive bending, using the site-approved mechanical protection.
What can cause a reading shift after replacing 330908-21-35-10-02-00?
Incorrect gap, target geometry, cable-length mismatch, nearby-probe cross-talk or damaged connectors can all affect the measurement.
What evidence should accompany a 330908-21-35-10-02-00 enquiry?
Provide the full probe code, extension cable and Proximitor numbers, mounting drawing, target material and current gap-voltage record.
