Product Overview

The Bently Nevada 330908-00-30-10-01-CN is a high-precision eddy current proximity probe part of the 3300 NSv (Narrow Sideview) transducer line. This specialized sensor is engineered for machinery with restricted installation clearances and small shaft diameters, typically under 51 mm (2 inches). By providing a non-contact interface for measuring shaft vibration and position, it serves as a critical data source for Turbine Supervisory Instrumentation (TSI) and asset protection systems.

This model features an 8mm tip diameter with a 3/8-24 UNF threaded body, designed for precise mounting through machine casings or bearing housings. The "CN" designation indicates a configuration optimized for regional compliance while adhering to Bently Nevada's global engineering standards for machinery protection.

Key Technical Characteristics

The 3300 NSv series is distinguished by its ability to maintain signal accuracy in tight spaces where standard proximity probes might experience magnetic interference from surrounding metal.

• Narrow Sideview Optimization: Designed with a magnetic field geometry that minimizes "side-view" interference, allowing for installation in shallow counterbores and small-diameter housings.

• Precision Signal Transmission: Equipped with a 1.0-meter integral cable and a gold-plated ClickLoc miniature coaxial connector, ensuring low-resistance electrical paths and high immunity to RFI/EMI.

• Robust Mechanical Design: Features a 3.0-inch case length for secure mounting and includes a connector protector to prevent mechanical strain and environmental contamination at the cable interface.

• Predictive Maintenance Capability: Delivers the high-fidelity dynamic vibration and static position data required to identify early-stage faults such as rotor unbalance, misalignment, and bearing wear.

• Interchangeability: Part of the 3300 XL NSv ecosystem, allowing for seamless integration with compatible Proximitor sensors and extension cables without the need for custom calibration.
