330903-17-19-05-02-00 Bently Nevada Proximity Probe
Description
The 330903 prefix indicates the probe belongs to the 3300 NSv (narrow side‑view) / 3300 XL proximity probe family. NSv probes are designed for installations with limited clearance or tight geometry, where standard (larger)
3300‑series probes might not fit.As a proximity (eddy‑current) probe, it performs non‑contact measurement of gap — the distance between its sensing tip and a conductive target (e.g. a steel shaft or rotor).
When used with a matching extension cable + signal conditioner (Proximitor) + monitor, the system can measure static shaft position / clearance, radial vibration / displacement, and dynamic vibration.
Thus, 330903‑series probes are designed for high‑precision shaft/rotor monitoring in rotating machinery — especially where mechanical space is limited.

FAQ
|
|
What does the probe measure? Static gap, vibration, dynamic displacement?
Yes — like other eddy‑current proximity probes, when paired with correct signal conditioner, it measures:
-
Static shaft / rotor position (gap / clearance)
-
Radial shaft vibration or displacement (dynamic motion)
-
If configured properly (target wheel or key‑way), and using suitable monitor, possibly speed / Keyphasor / phase‑reference signals.
|
|
What do I need to use it properly (besides the probe)?
You need:
-
A compatible extension cable + connector (matching electrical length) — NSv probes use 75 Ω coaxial cables with ClickLoc connectors.
-
A Proximitor (signal conditioner) + monitoring module / monitor designed for 3300‑series probes — the raw eddy‑current signal from the probe must be conditioned to provide a usable output (voltage, displacement, vibration amplitude, etc.).
-
Proper installation: correct mounting (M8 × 1 thread), correct gap to the conductive target, correct connector torque, good cable routing, shielding / grounding as required.
|
|
What are the probe’s expected limitations or constraints?
-
Because 330903 variant is narrow side‑view, it has a smaller thread and body than older / full-size 3300 probes — may not be suitable for large-diameter shafts or where heavy mechanical loads / impacts are expected.
-
The linear measurement range is limited (e.g., ~0.25–1.75 mm) — ensure your application’s required gap/clearance is within that range for accurate linear output.
-
The suffix “17‑19‑…” is nonstandard — there may be non‑documented mechanical or electrical differences (e.g. altered case length, cable length, connector type, internal wiring), which could impact mounting, wiring, compatibility — therefore you must verify with vendor / manufacturer.
-
As with any eddy‑current proximity probe: measurement assumes a conductive metallic target (shaft, rotor). Using non‑standard materials or unusual target geometry may degrade accuracy or linearity.
-
The NSv “narrow” design trades off robustness compared to older full‑size armored probes — if the application involves high mechanical risk (impact, heavy vibration, potential contact), consider if a more rugged (armored) probe is more appropriate.
