Bently Nevada 330905-00-18-05-02-05 3300 NSv Proximity Probe

The Bently Nevada 330905-00-18-05-02-05 serves as a non-contacting displacement sensor for industrial machinery. This Narrow Side-view (NSv) probe specifically targets applications with restricted spatial clearances. It measures radial vibration and axial position by detecting eddy current changes near the shaft. The reverse mount design facilitates installation from the rear of the probe housing. This feature simplifies maintenance in complex compressor or pump configurations.

Structural Integrity and Connector Technology

Engineers designed this probe to withstand the physical rigors of heavy industrial environments. The unit features a patented TipLoc molding that secures the probe tip permanently. Furthermore, the CableLoc design provides superior strain relief for the internal wiring. This assembly successfully resists up to 220 Newtons of pull force. The gold-plated ClickLoc connectors ensure a stable electrical signal without degradation over time.

Application Scope and System Integration

This sensor excels in monitoring small-diameter shafts and confined bearing housings. It proves especially effective for high-speed centrifugal compressors and refrigeration units. The 3300 NSv system maintains full compatibility with legacy 3300 series transducers. Consequently, plant operators can upgrade existing monitoring systems without replacing all hardware. The module supports SIL 2 requirements for safety-instrumented functions in hazardous zones.

Physical and Electrical Specifications

• Mounting Style: Reverse Mount 3/8-24 UNF threads
• Cable Length: 18-inch (0.46 meter) integrated lead
• Connector Type: Miniature coaxial ClickLoc with connector protector
• Certification: ATEX/IECEx hazardous area approved
• Tip Diameter: Approximately 5 mm for narrow side-view capability

Performance Characteristics

The probe delivers a linear output when paired with a matching Proximitor. This allows for the detection of even microscopic shaft movements. The system provides a standard scale factor for reliable data interpretation. Integrated shielding prevents electromagnetic interference from affecting the vibration readings. This ensures high-fidelity data for turbine supervisory instrumentation (TSI) systems.
