330881-28-06-145-00-02 Technical Description, Specifications, Applications, Advantages and Model Reference Guide
Product Overview
The 330881-28-06-145-00-02 is a precision industrial proximity probe used for continuous monitoring of shaft displacement and vibration in rotating machinery. It is designed for non-contact measurement of dynamic shaft movement, making it suitable for high-speed and heavy-duty industrial equipment where reliability and stability are essential.
The probe uses eddy current sensing technology to measure the distance between the probe tip and a conductive metal surface. This allows accurate detection of shaft position, radial vibration, axial displacement, and mechanical eccentricity without any physical contact.
Because there is no mechanical wear involved, the probe maintains long-term measurement stability even in harsh industrial environments. It is widely used in machinery protection systems where continuous monitoring is required to prevent equipment failure and reduce unplanned downtime.
The 145 mm probe length version provides flexible installation options in machinery where medium-depth mounting is required, making it suitable for a wide range of rotating equipment configurations.

Product Features
The 330881-28-06-145-00-02 provides highly stable and accurate shaft displacement measurement without any physical contact with the rotating surface.
Its eddy current sensing mechanism ensures precise detection of small changes in shaft movement, allowing early identification of imbalance, misalignment, looseness, or bearing wear.
The stainless-steel housing improves durability and ensures reliable performance in environments exposed to oil, dust, vibration, and temperature fluctuations.
The probe is designed for continuous operation in industrial machinery protection systems, making it suitable for long-term monitoring without performance degradation.
Its fast response capability ensures real-time tracking of dynamic shaft behavior, which is critical for early fault detection in high-speed rotating equipment.
The compact mechanical design allows flexible installation even in space-constrained machinery environments.
Working Principle
The probe operates using eddy current technology.
A high-frequency electromagnetic field is generated at the probe tip. When a conductive metal surface approaches the field, eddy currents are induced in the material.
These eddy currents change the electromagnetic impedance of the probe system. This change is converted into an electrical signal proportional to the distance between the probe and the shaft surface.
Since the system is non-contact, it eliminates mechanical wear and ensures stable long-term measurement performance.
