1. Product Overview — Bently Nevada 330980‑51‑CN
Introduction
The 330980‑51‑CN is a proximitor (eddy‑current non‑contact displacement / vibration sensor) in the 3300 XL NSv family. The “51” indicates a 5.0 m system length and DIN‑compatible slim mounting form. The suffix “CN” denotes a regional / China compliance version (i.e. labeling, certifications, or packaging aligned with China / Asia market requirements). This sensor is engineered for use in tight mechanical spaces while meeting local regulatory demands.
The 330980‑51‑CN accepts 3300 NSv or RAM probes + extension cables and converts the probe’s gap variation (as shaft moves) into a voltage output. It offers improved electromagnetic compatibility (EMC) to maintain signal integrity under field conditions.

Notes & Context
-
Some listings show a weight of 0.22 kg for 330980‑51‑CN, likely referring to a different sub-variant (e.g. unpacked module) ([turn0search10]).
-
The published dimension 81.3 × 61.2 × 63.5 mm appears consistently in several vendor datasheets.
-
The “CN” suffix typically does not change the core electrical/mechanical performance — it indicates region-specific compliance.
3. Applications
The 330980‑51‑CN sensor is used in industrial monitoring tasks, particularly in constrained installation environments. Typical use cases:
-
Monitoring shaft vibration / displacement on turbines, compressors, motors
-
Axial (thrust) position measurement when flat faces or narrow envelopes are required
-
Keyphasor / phase reference signal in machine systems
-
Retrofitting older RAM / 190 / 3300 sensors into compact machinery layouts
-
Use in petrochemical, power generation, oil & gas, and advanced manufacturing plants
-
Environments requiring China‑approved sensors where local compliance matters
Its slim DIN form and regional compliance make it suitable where both geometry and regulations are constraints.
4. Advantages & Key Features
