Product Overview

The Bently Nevada 330191-00-33-90-05 is a specialized 8mm proximity sensor designed for Extended Temperature Range (ETR) applications. As a fundamental part of the 3300 XL transducer series, this probe is specifically engineered to perform in extreme thermal environments where standard sensors would lose accuracy or fail. It provides non-contacting measurement of shaft vibration and axial displacement, facilitating the protection of critical rotating machinery.

This specific configuration features an integrated 9.0-meter cable, allowing for a direct connection to a Proximitor sensor over long distances without the need for additional extension cables. This reduces potential signal interference and simplifies installation in large-scale Turbine Supervisory Instrumentation (TSI) setups. By monitoring fluid-film bearing machines, the 330191-00-33-90-05 ensures reliable data for Keyphasor phase reference and rotational speed monitoring in the most demanding industrial sectors.

Key Technical Characteristics

• Advanced Structural Integrity: Utilizes the patented TipLoc molding process to create an exceptionally robust bond between the 8mm probe tip and the body, preventing detachment under mechanical stress.

• CableLoc Retention Technology: Features a high-strength cable-to-probe connection capable of withstanding pull-off forces up to 330 N (75 lbf), ensuring the 9-meter lead remains secure.

• Gold-Plated ClickLoc Connectors: Equipped with miniature coaxial connectors that feature an audible "click" locking mechanism. These gold-plated junctions are corrosion-resistant and require only finger-tightening to maintain a vibration-proof electrical path.

• Extreme Heat Resilience: Engineered as an ETR (Extended Temperature Range) component, this probe maintains precise measurement linearity and scale factor stability even when exposed to elevated operating temperatures.

• FluidLoc Migration Prevention: This probe configuration supports FluidLoc technology, which seals the internal cable structure to prevent oil or other process liquids from wicking through the cable into the electronics enclosure.

• Hazardous Area Certification: Fully compliant with international safety standards, including ATEX, IECEx, and CSA, allowing for safe deployment in potentially explosive industrial zones.
