Product Overview

The 330980-50-CN is a high-performance signal conditioning unit belonging to the Bently Nevada 3300 XL Narrow Side View (NSv) Transducer System. This Proximitor Sensor is engineered specifically for machinery where standard 8 mm proximity systems cannot be utilized due to restricted "side-view" clearances or small shaft diameters. By converting the Radio Frequency (RF) signal from a proximity probe into a linear voltage output, the 330980-50-CN enables precise monitoring of radial vibration and axial position. This model is configured for a 5.0-meter total system length, providing a vital interface for Turbine Supervisory Instrumentation (TSI) in high-speed rotating equipment.

Core Technical Characteristics

The 330980-50-CN Proximitor provides specialized sensing capabilities for complex industrial geometries:

• System Configuration: Optimized for a 5.0-meter (16.4 feet) total calibrated loop including probe and extension cable.

• Small Target Performance: Calibrated for accurate data acquisition on shafts smaller than 51 mm (2.0 inches) and flat axial targets smaller than 15 mm (0.6 inches).

• Scale Factor: Delivers a standardized linear output of 7.87 V/mm (200 mV/mil) for high-resolution measurement.

• Operating Range: Features a 1.5 mm (60 mil) linear sensing range, tailored for the unique requirements of the NSv probe series.

• Signal Integrity: Built-in RFI/EMI immunity protects the displacement signal from electromagnetic interference, ensuring stable data in high-voltage industrial environments.

Mechanical and Environmental Specifications

• Installation: Designed for high-density DIN rail mounting or traditional bulkhead panel installations.

• Wiring Connectivity: Features SpringLoc terminal strips that provide secure, vibration-resistant connections without the need for specialized tools.

• Temperature Resilience: Capable of operating in extreme industrial climates ranging from -52°C to +100°C (-62°F to +212°F) for the Proximitor unit itself.

• Approval Rating: Carries the "CN" suffix, indicating compliance with specific regional standards and hazardous area certifications.

Industrial Applications

As a primary component for machinery protection and predictive maintenance, the 330980-50-CN is essential for:

• Compact Machinery: Monitoring centrifugal air compressors, refrigeration compressors, and small process gas machinery where internal clearances are tight.

• Vibration Diagnostics: Measuring radial shaft motion in fluid-film bearings to detect imbalances, misalignments, or bearing wear.

• Thrust Monitoring: Tracking axial displacement to prevent catastrophic contact between rotating and stationary internal components.

• System Retrofits: Serving as a modern upgrade for legacy 3300 series or RAM transducer systems while maintaining compatibility with standard 3500 monitoring racks.
