330876-02-50-01-00 Technical Overview, Specifications, Applications, Advantages and Model Reference Guide
Product Overview
The 330876-02-50-01-00 is a high-precision industrial proximity probe designed for continuous monitoring of shaft vibration and displacement in rotating machinery systems. It is widely used in condition monitoring and machinery protection applications where accurate, stable, and real-time measurement of rotor behavior is required.
This probe is based on eddy current non-contact measurement technology. It measures the distance between the probe tip and a conductive metal surface without physical contact, allowing accurate detection of shaft position, radial vibration, axial displacement, and eccentricity.
Because the sensing process is non-contact, there is no mechanical wear between the probe and the rotating shaft. This ensures long-term stability, high reliability, and consistent measurement performance in demanding industrial environments.
The 50 mm probe length configuration is designed for compact installation requirements, making it suitable for equipment with limited mounting space or shallow installation depth.

Product Features
The 330876-02-50-01-00 provides stable and accurate non-contact measurement of shaft displacement in rotating machinery.
Its eddy current sensing technology enables precise detection of small shaft movement variations, supporting early identification of mechanical faults such as imbalance, misalignment, looseness, or bearing wear.
The 50 mm probe length is optimized for compact installations, making it suitable for equipment with limited installation depth.
The stainless-steel housing ensures durability and resistance to vibration, oil exposure, dust, and industrial environmental conditions.
The probe is designed for continuous monitoring and delivers stable long-term measurement performance with minimal maintenance requirements.
Its fast dynamic response allows real-time tracking 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 long-term stable operation.
