Description

The Bently Nevada 330180-90-05 is a 3300 XL Proximitor Sensor designed as a critical component of the 3300 XL 8mm Proximity Transducer System. This sensor provides an output voltage directly proportional to the distance between the probe tip and the observed conductive surface, enabling precise measurement of both static (position) and dynamic (vibration) values. It is widely utilized for monitoring fluid-film bearing machines, as well as for Keyphasor reference and speed measurements.

Features

• Designed for high-accuracy vibration and position monitoring in industrial machinery.
• Supports both high-density DIN-rail installations and traditional 4-hole panel mount configurations.
• Integrated mounting base provides electrical isolation, eliminating the need for separate isolator plates.
• Enhanced RFI/EMI immunity allows for installation in non-metallic (fiberglass) housings without requiring special shielded conduit.
• Complete interchangeability of probes, extension cables, and sensors, removing the need for component-specific bench calibration.

Applications

• Fluid-Film Bearing Machines: Radial vibration and axial (thrust) position monitoring.
• Compression Systems: Centrifugal air, refrigeration, and process gas compressors.
• High-Speed Rotors: Turbines, motors, and pumps requiring precise shaft dynamics for predictive maintenance.
• Speed Monitoring: Provides tachometer and Keyphasor phase reference signals.

Technical Specifications

Installation Guidelines

• Ensure the system is powered down before connecting or disconnecting the Proximitor sensor.
• The sensor supports both DIN-rail and 4-hole panel mounting; ensure the mounting surface is clean and provides a stable ground reference if required.
• While the sensor has high RFI/EMI immunity, follow standard industrial practices for routing signal cables away from high-voltage power lines to prevent induced noise.
• Verify that the total system length (probe + extension cable + sensor) matches the 9.0-meter configuration to ensure calibration accuracy.
• Ensure the probe gap is set correctly, typically resulting in a gap voltage of -9 V to -11 V DC for centered shafts.
