Product Introduction
The 330103-00-05-10-01 is a 3300 XL 8 mm Proximity Probe from Bently Nevada. This part number represents the probe component of the 3300 XL series eddy current proximity probe system, which is designed for non-contact measurement of shaft vibration, position, and eccentricity in rotating machinery. The probe operates on the eddy current principle, providing high linearity, excellent temperature stability, and reliable performance in harsh industrial environments. It is a key component in API 670 compliant machinery protection systems and is commonly used in critical turbomachinery applications.

Application Scenarios
Radial Vibration Monitoring – Measures shaft vibration in steam turbines, gas turbines, compressors, and generators to detect imbalance, misalignment, and bearing faults.
Axial (Thrust) Position Monitoring – Monitors shaft axial displacement to ensure proper rotor positioning within bearing clearances and prevent thrust bearing failure.
Shaft Eccentricity Measurement – Used during turbine startup to detect shaft bow and avoid rotor-to-stator contact.
Differential Expansion Monitoring – Applied in combination with other sensors to measure thermal growth between rotor and casing in large turbomachinery.
Keyphasor® Reference Applications – Provides once-per-turn timing signal for phase measurement and synchronous vibration analysis when used with a gear tooth or keyway target.
Power Generation, Oil & Gas, and Heavy Industrial Applications – Deployed in critical rotating machinery protection systems requiring API 670 compliance and high reliability.
