330881-28-08-060-00-02 Technical Overview, Specifications, Applications, Advantages and Related Model Guide
Product Overview
The 330881-28-08-060-00-02 is a high-precision non-contact proximity probe designed for continuous monitoring of shaft vibration and displacement in rotating machinery. It is used in industrial condition monitoring systems where accurate, real-time measurement of rotor behavior is required for equipment protection and predictive maintenance.
The probe operates using eddy current sensing technology, which allows it to measure the distance between the probe tip and a conductive metal target without physical contact. This enables precise detection of shaft position, radial vibration, axial displacement, and mechanical eccentricity.
Because there is no physical contact between the probe and the rotating shaft, wear is eliminated and long-term measurement stability is maintained. This makes the device suitable for continuous operation in demanding industrial environments such as turbines, compressors, pumps, and generators.
The 060 mm probe length configuration is designed for compact to medium-depth installations, offering flexibility for machinery where space and mounting conditions require a shorter sensing probe.

Product Features
The 330881-28-08-060-00-02 is designed for stable and accurate shaft displacement monitoring in rotating machinery without physical contact.
Its eddy current sensing technology ensures precise detection of small changes in shaft position, allowing early identification of imbalance, misalignment, looseness, or bearing degradation.
The 60 mm probe length provides a balanced installation option suitable for medium-space mechanical configurations.
The stainless-steel housing enhances durability and ensures resistance to oil, vibration, dust, and industrial contaminants.
The probe supports continuous operation and delivers stable long-term measurement performance with minimal maintenance requirements.
Its fast response capability allows real-time monitoring of dynamic shaft behavior, which is critical for machinery protection systems.
Working Principle
The probe operates based on 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 impedance of the probe system. The change is converted into an electrical signal proportional to the distance between the probe tip and the shaft.
Because the system is non-contact, it eliminates mechanical wear and ensures stable long-term operation.
