Product Introduction
The 330903-00-05-10-01-05 is a precision non-contact eddy current proximity probe designed for continuous measurement of shaft vibration, shaft position, radial displacement, and axial movement in rotating machinery.
The probe operates without physical contact with the shaft, ensuring accurate measurement while eliminating mechanical wear. Any shaft movement caused by imbalance, misalignment, bearing wear, rotor instability, thermal expansion, or mechanical looseness is converted into an electrical signal for condition monitoring and analysis.
It is designed for long-term operation in harsh industrial environments such as high temperature zones, oil mist areas, dusty environments, and high vibration conditions.
The compact structure allows installation in tight spaces such as bearing housings and machine internals.
Working Principle
The probe operates using eddy current sensing technology.
A high-frequency electromagnetic field is generated at the probe tip.
When a conductive metal shaft enters the field, eddy currents are induced on the surface.
These eddy currents modify the impedance of the probe system.
The signal conditioning module converts these impedance variations into a proportional analog voltage output representing shaft displacement.
This non-contact principle ensures stable, accurate, and long-term reliable measurement.
