Introduction
The model 330703-000-050-10-02-00 is a 3300 XL 8mm Proximity Transducer System from Baker Hughes Bently Nevada. This is a complete, pre-calibrated kit designed for measuring shaft relative vibration and position on rotating machinery. The system includes an 8mm proximity probe, an extension cable, and a proximitor (oscillator/demodulator) that are factory-matched to ensure optimal performance and accuracy. The specific suffix -050 indicates a 5-meter (5000mm) extension cable, and -10-02 defines the connector types. This system is a cornerstone for API 670 compliant machinery protection.

Application Scenarios
This system is a critical component for protecting and monitoring high-value rotating machinery across various industries.
Radial Vibration Monitoring on Critical Equipment:
Primarily used to measure shaft relative vibration on turbines, compressors, large pumps, and generators. It is the primary sensor for API 670 compliant machinery protection systems, providing essential data for alarms and shutdowns.
Axial Position Thrust Monitoring:
Used to monitor the axial (thrust) position of a rotor to prevent catastrophic damage from excessive movement that could cause thrust collar and bearing failure.
Differential Expansion Monitoring:
On large steam turbines, these systems can be used to measure the differential expansion between the rotor and the stator casing.
Rotating Machinery Commissioning and Diagnostics:
Used during machine startup and alignment to establish baseline vibration levels, centerline position, and to diagnose dynamic behaviors like oil whirl and shaft instability.
OEM Integration:
Supplied as the standard vibration monitoring system by original equipment manufacturers (OEMs) for their turbines, compressors, and other high-speed machinery, ensuring a pre-calibrated, reliable solution.
