Product Overview
The Bently Nevada 330180-X1-05 is a 3300 XL Proximitor (signal conditioner/oscillator-driver) that works with the 143416-48 probe and extension cable to form a complete eddy-current proximity transducer system. The "-05" suffix indicates hazardous area approvals (e.g., ATEX, CSA, IECEx). This system provides non-contact measurement of shaft vibration, axial (thrust) position, and eccentricity on rotating machinery.
The 143416-48 typically denotes a 5 mm or 8 mm diameter probe with an integral or extension cable, designed for use with the 3300 XL Proximitor. The system outputs a precise analog voltage proportional to the gap between the probe tip and the conductive target surface.

Application Scenarios
The 330180-X1-05 + 143416-48 is used in machinery protection and condition monitoring systems where non-contact, high-reliability measurement is required.
Primary Applications:
Radial Vibration Monitoring
Measuring shaft vibration relative to bearing housing on steam turbines, gas turbines, compressors, and pumps.
Provides early warning of unbalance, misalignment, or bearing degradation.
Axial (Thrust) Position Monitoring
Detecting axial movement of rotating shafts to prevent thrust bearing damage.
Critical for compressors and large turbines where axial shift indicates impending failure.
Shaft Eccentricity Measurement
Monitoring shaft bow during startup and slow-roll conditions.
Prevents rotor-to-stator rub during turbine startup.
Keyphasor / Speed Sensing
Detecting once-per-turn reference marks for phase measurement and speed detection.
Used with 3500 series monitors for synchronous vibration analysis.
Hazardous Area Installations
Oil refineries, chemical plants, and gas compression stations (due to -05 approvals).
Monitors critical machinery in ATEX/IECEx classified zones.
