330881-28-10-148-03-02 Technical Overview, Specifications, Applications, Advantages and Model Reference Guide
Product Overview
The 330881-28-10-148-03-02 is a precision industrial proximity probe designed for continuous monitoring of shaft vibration and displacement in rotating machinery systems. It is widely used in condition monitoring and machinery protection applications where accurate real-time measurement of rotor dynamics is required.
This probe operates using eddy current non-contact sensing technology. It measures the distance between the probe tip and a conductive metal surface without physical contact, enabling precise detection of shaft position, radial vibration, axial displacement, and eccentricity.
Because the measurement is non-contact, there is no mechanical wear between the probe and the rotating shaft. This ensures stable long-term operation, high reliability, and consistent measurement accuracy even in harsh industrial environments.
The 148 mm probe length configuration is designed for deep installation requirements, making it suitable for large machinery or structures requiring extended probe reach.

Product Features
The 330881-28-10-148-03-02 provides stable and high-accuracy non-contact measurement of shaft displacement in rotating machinery.
Its eddy current sensing technology enables precise detection of small variations in shaft movement, supporting early identification of mechanical issues such as imbalance, misalignment, looseness, or bearing degradation.
The 148 mm probe length supports deep installation requirements, making it suitable for large machinery and complex mechanical assemblies.
The stainless-steel housing ensures strong durability and resistance to vibration, oil exposure, dust, and harsh industrial environments.
The probe is designed for continuous operation and delivers stable long-term measurement performance with minimal maintenance requirements.
Its fast response capability allows real-time tracking of dynamic shaft behavior in high-speed rotating equipment.
Working Principle
The probe operates using eddy current induction technology.
A high-frequency electromagnetic field is generated at the probe tip. When a conductive rotating shaft enters this field, eddy currents are induced in the metal surface.
These eddy currents modify the electromagnetic impedance of the probe system. The change is converted into an electrical signal proportional to the distance between probe and shaft.
Because the system is non-contact, it eliminates mechanical wear and ensures long-term stable operation.
