Description
Overview
The Bently Nevada 330103‑17‑22‑10‑12‑05 proximity probe is an extended‑reach 8 mm sensor designed for high‑accuracy displacement and vibration measurement in fluid‑film bearing machinery. Its long unthreaded and case lengths support installations where the sensing point is located deeper within the machine housing. The probe incorporates a FluidLoc‑protected cable, offering superior resistance to oil ingress in lubrication‑rich environments.
Key Characteristics

Functional Description
The 330103‑17‑22‑10‑12‑05 probe is engineered for installations requiring extended reach into machine housings, bearing pedestals, or confined structural cavities. Its FluidLoc cable construction prevents oil penetration, ensuring long‑term signal stability in lubrication‑intensive environments such as turbines and compressors.
As part of the 3300 XL system, the probe works with matched extension cables and Proximitor sensors to deliver accurate monitoring of:
The probe maintains the standard 4‑hole mounting pattern used across the 3300 family, simplifying retrofits and system upgrades. Its hazardous‑area certifications support deployment in oil & gas, power generation, and heavy industrial facilities.
Application Scenarios
-
Steam and gas turbines
-
Centrifugal and axial compressors
-
Gearboxes and industrial pumps
-
Machinery requiring deep‑reach probe installation
-
Oil‑rich environments where cable protection is critical
FAQ
Q: What makes the FluidLoc cable different from standard probe cables? A: FluidLoc provides enhanced resistance to oil penetration, improving long‑term reliability in lubrication‑exposed installations.
Q: Can this probe replace older 3300 8 mm probes? A: Yes. It is electrically and mechanically compatible when installed with matched cable lengths.
Q: Is this probe suitable for hazardous areas? A: It carries CSA, ATEX, and IECEx certifications for global hazardous‑location compliance.
