Product Overview — Bently Nevada 330100‑90‑05
Product Introduction
The 330100‑90‑05 is a Proximitor® (proximity) non‑contact sensor from the 3300 series, intended to measure the position of a target (often a shaft or rotating part) relative to the sensor tip. It provides vibration, displacement or gap measurements with high precision, used in industrial rotating machinery protection systems. The sensor includes a probe, cable, and tip, and is designed for durability in harsh environments. The suffix “90‑05” denotes a cable length option (9.0 meters) and multiple agency approvals or equivalent quality / safety certification.

Related and Similar Models (Same Series or Closely Related)
Below are five other models in the same 3300 Proximitor / proximity sensor family or closely functionally related, with comparison of parameters.
| Model | Application / Purpose | Sensing / Key Features | Dimensions / Weight | Distinctive Traits |
|---|---|---|---|---|
| 330100‑XX‑00 | Base proximity sensor with shorter cable options | Same type proximity sensing, variable cable lengths | Similar probe size; weight similar (~0.25‑0.3 kg) | Useful when long cable not required |
| 330100‑90‑00 | Similar model with 9.0 m cable but without multiple agency approvals | Same 5 mm gap, 9 m cable | Slightly less weight due to fewer approvals | Less regulatory overhead; lower cost |
| 330100‑80‑05 | With 8.0 m cable and approvals | Similar sensing, perhaps marginally shorter cable | Weight similar, possibly slightly less | Option when 9 m is more than needed |
| 330101‑00‑40‑10‑02‑05 | Proximitor probe with different probe bore/diameter | Possibly different nominal gap, or fitted for specific mount | Probe physical dimensions may vary; weight approx similar | Better fit for specific mounting holes or shaft configurations |
| 330980‑50‑05 | 3300 XL NSv proximity probe system | Enhanced probe specification, maybe larger sensor tip or higher sensitivity | Heavier, larger probe size | For more demanding vibration or displacement measurement tasks |
