330881-28-10-142-03-02 Technical Overview, Specifications, Applications, Advantages and Model Reference Guide

Product Overview

The 330881-28-10-142-03-02 is a high-precision industrial proximity probe designed for continuous monitoring of shaft vibration and displacement in rotating machinery. It is widely used in machinery protection and condition monitoring systems where accurate, real-time measurement of rotor dynamics is essential.

The probe operates based on eddy current non-contact measurement technology. It measures the distance between the probe tip and a conductive metallic target 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 shaft surface. This ensures long-term stability, high reliability, and consistent measurement accuracy even under harsh industrial operating conditions.

The 142 mm probe length configuration is designed for deep installation applications, making it suitable for machinery with larger mounting depth requirements and more complex mechanical structures.

Technical Specifications

Product Features

The 330881-28-10-142-03-02 provides stable and accurate shaft displacement measurement in rotating machinery without physical contact.

Its eddy current sensing technology allows precise detection of small changes in shaft movement, enabling early identification of mechanical faults such as imbalance, misalignment, looseness, or bearing wear.

The 142 mm probe length supports deep installation requirements, making it suitable for larger machinery configurations.

The stainless-steel housing provides strong resistance to vibration, oil contamination, dust, and harsh industrial environments.

The probe is designed for continuous monitoring applications and delivers stable long-term performance with minimal maintenance requirements.

Its fast response capability enables real-time tracking of shaft dynamics in high-speed rotating machinery.

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.
