Bently Nevada 330980-50-CN 3300 XL NSv Proximitor Sensor

Description

The Bently Nevada 330980-50-CN is a high-performance proximity sensor designed for use within the 3300 XL NSv Proximity Transducer System. This Proximitor Sensor is specifically optimized for industrial machinery with tight installation requirements, small targets, or where counterbore and side-view restrictions limit standard transducer systems. The 330980-50-CN model features a 5.0-meter system length option configuration specifically engineered for panel mounting, providing an average scale factor of 7.87 V/mm (200 mV/mil) over a 1.5 mm (60 mils) linear range. It plays a critical role in fluid-filmed bearing machinery by converting eddy current signals from a proximity probe into a proportional voltage output for continuous vibration, speed, and position monitoring.

Features

• Provides an Average Scale Factor of 7.87 V/mm (200 mV/mil) for precise proximity measurements.
• Compact and thin design allows high-density installation configurations.
• Equipped with SpringLoc terminal strips for fast, secure field wiring without specialized tools.
• Enhanced RFI/EMI immunity prevents adjacent high-frequency radio signals from impacting system operation.
• Integrated protection against electrostatic discharge on terminals and connectors.

Applications

• Centrifugal air compressors 
• Refrigeration compressors 
• Process gas compressors 
• Radial vibration and radial position measurements on small shafts 
• Axial (thrust) position measurements on small flat targets 
• Tachometer, zero speed, and phase reference (Keyphasor) signaling

Installation Guidelines

• Mounting Configuration: The device is configured for traditional panel mounting. Ensure secure fastening to prevent structural vibration from affecting performance.
• Field Wiring: Use three-conductor shielded triad cable for connection to the monitor. Strip wires and connect via the tool-free SpringLoc terminal strips.
• Electrostatic Discharge (ESD): Observe proper ESD precautions during handling and installation to protect internal electronics.
• Connector Protection: Use connector protectors on probe-to-cable and cable-to-sensor connections to prevent fluid ingress.
