330881-28-09-080-03-02 Technical Overview, Specifications, Applications, Advantages and Related Model Guide

Product Overview

The 330881-28-09-080-03-02 is a precision non-contact proximity probe designed for continuous measurement of shaft vibration and displacement in rotating machinery. It is widely used in industrial condition monitoring systems where accurate and stable real-time measurement is required for machinery protection and predictive maintenance.

The probe operates based on eddy current sensing technology. It measures the distance between the probe tip and a conductive metal target without physical contact, allowing precise detection of shaft position, radial vibration, axial displacement, and eccentricity.

Because it does not require physical contact with the rotating shaft, the probe eliminates mechanical wear and ensures long-term measurement stability. It is suitable for continuous operation in harsh industrial environments where reliability is critical.

The 080 mm probe length configuration is designed for medium installation depth requirements, providing a balanced option between compact installation and deeper mounting applications.

Technical Specifications

Product Features

The 330881-28-09-080-03-02 provides stable and accurate non-contact measurement of shaft displacement in rotating machinery.

Its eddy current sensing technology ensures precise detection of small shaft movement variations, enabling early identification of mechanical issues such as imbalance, misalignment, looseness, or bearing wear.

The 80 mm probe length provides a balanced installation depth suitable for a wide range of machinery configurations.

The stainless-steel housing ensures durability and resistance to vibration, oil, dust, and industrial environmental stress.

The probe supports continuous monitoring and delivers stable long-term performance with minimal maintenance requirements.

Its fast response capability allows real-time tracking of shaft dynamics 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 the 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 stable long-term operation.
