Product Overview

The 330910-00-10-50-02-05 is a specialized Narrow Side View (NSv) proximity transducer probe developed by Bently Nevada for high-precision displacement monitoring. This sensor is specifically engineered for industrial applications where standard 8 mm or 5 mm probes are unsuitable due to tight spatial envelopes, such as small counterbores or restricted "side-view" clearances. By utilizing eddy current technology, the probe captures radial shaft vibration and axial thrust position on rotating assets, providing critical data for Turbine Supervisory Instrumentation (TSI) systems. It is the primary solution for monitoring centrifugal air compressors, refrigeration compressors, and small-bore process machinery.

Technical Configuration

Engineering for Restricted Spaces

The 3300 NSv series incorporates advanced material science and design to ensure survivability in demanding environments:

• Narrow Side View Capability: The probe tip and internal coil are shielded to ignore surrounding conductive material, allowing for accurate measurements on shafts as small as 51 mm (2 inches) or inside small counterbores.

• Patented TipLoc Construction: The Polyphenylene Sulfide (PPS) probe tip is molecularly bonded to the stainless steel body, creating a vacuum-tight seal that prevents oil and process moisture from wicking into the sensor.

• CableLoc Integrity: Designed with a robust cable-to-body connection that provides 220 N (50 lb) of pull strength, ensuring electrical continuity under extreme mechanical stress.

• ClickLoc Connectivity: Features gold-plated connectors with a self-locking mechanism to maintain a corrosion-resistant, vibration-proof signal path.

Industrial Applications and Integration

The 330910-00-10-50-02-05 is a key component in predictive maintenance and machinery protection strategies:

• Asset Protection: Ideal for centrifugal compressors and high-speed pumps where internal mounting space is limited.

• Diagnostic Accuracy: Delivers clean signals for Keyphasor phase reference and speed detection, essential for advanced rotor dynamic analysis.

• Electromagnetic Immunity: Engineered to exceed CE standards for RFI/EMI protection, ensuring signal stability near high-frequency industrial noise.

• Ease of Installation: Compatible with high-density DIN-rail or bulkhead mounting through matching 3300 NSv Proximitor sensors, featuring tool-free SpringLoc wiring terminals.
