330881-28-10-112-03-02 Technical Overview, Specifications, Applications, Advantages and Model Reference Guide
Product Overview
The 330881-28-10-112-03-02 is a high-precision non-contact proximity probe designed for continuous measurement of shaft vibration and displacement in rotating machinery. It is widely applied in industrial condition monitoring systems where accurate, real-time tracking of rotor dynamics is required for equipment protection and predictive maintenance.
The probe uses eddy current sensing technology, which enables it to measure the distance between the probe tip and a conductive metallic target without physical contact. This allows accurate detection of shaft position, radial vibration, axial displacement, and eccentricity under dynamic operating conditions.
Because the system operates without physical contact, it eliminates mechanical wear and ensures stable long-term performance even in harsh industrial environments. It is suitable for continuous monitoring of critical rotating machinery in heavy-duty industrial applications.
The 112 mm probe length configuration provides a versatile installation depth suitable for medium-to-deep mounting requirements, making it applicable to a wide range of machinery layouts.

Product Features
The 330881-28-10-112-03-02 provides stable and accurate measurement of shaft displacement in rotating machinery without physical contact.
Its eddy current sensing technology enables precise detection of small changes in shaft motion, supporting early identification of mechanical issues such as imbalance, misalignment, looseness, or bearing wear.
The 112 mm probe length provides flexible installation for medium-to-deep mounting conditions across different machinery configurations.
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, offering stable long-term measurement performance with minimal maintenance requirements.
Its fast dynamic response enables real-time monitoring of shaft behavior 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 stable long-term operation.
