Sensor Proximitor Bently Nevada 330980-50-00 3300 XL NSv

Description

The 330980-50-00 is a non-contacting proximity sensor designed for use within the 3300 XL NSv Proximity Transducer System. This sensor is engineered for machines with tight installation requirements, such as centrifugal air compressors, refrigeration compressors, and process gas compressors, where counter bore, sideview, or rearview restrictions limit the use of standard transducer systems. The 330980-50-00 functions by outputting an Average Scale Factor of 7.87 V/mm (200 mV/mil), which is ideal for small target applications such as measuring radial vibration on shafts smaller than 51 mm or axial position on flat targets smaller than 15 mm.

This Proximitor Sensor features a thin design optimized for traditional panel mount configurations. It provides advanced RFI/EMI immunity that prevents nearby high-frequency radio signals from adversely affecting the transducer system, enabling it to achieve European CE mark approvals without specialized mounting considerations. Additionally, the device is equipped with SpringLoc terminal strips that require no special installation tools, facilitating robust and fast field wiring connections.

Features

• Optimized for space-restricted industrial applications with a thin and compact panel-mount design.
• Features an integrated SpringLoc terminal strip to accelerate field installation and maximize wiring robustness without special tools.
• Provides high RFI/EMI immunity to resist electromagnetic noise from nearby high-frequency radio devices.
• Protects internal transducer electronics against electrostatic discharge at the terminals and connector interfaces.
• Capable of driving direct replacements for legacy 3300 RAM and 3000-series or 7000-series 190 Transducer Systems.

Applications

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

Installation Guidelines

• Panel Mounting: Secure the device into the designated housing or junction box plate using the integrated panel-mount base orientation.
• Field Wiring: Connect field wiring using 0.2 to 1.5 mm2 (16 to 24 AWG) conductors, or 0.25 to 0.75 mm2 (18 to 23 AWG) if using ferrules. A three-conductor shielded triad cable is recommended.
• Maximum Cable Length: Ensure the total distance between the Proximitor Sensor and the associated monitor does not exceed 305 meters (1000 feet).
• ESD Prevention: While terminal and connector tracks include internal protection circuits, use an ESD wrist strap and standard grounding practices during handling and field terminal wire connections to avoid electrostatic discharge damage.
