The 330881-28-08-120-00-02 is a 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 stable, accurate, and real-time measurement of rotor behavior is required.
The probe operates using eddy current non-contact sensing technology. It measures the distance between the probe tip and a conductive metal surface without physical contact, enabling accurate detection of shaft position, radial vibration, axial displacement, and eccentricity.
Because the measurement is non-contact, there is no mechanical wear between the probe and the target shaft. This ensures long-term stability, high reliability, and consistent measurement accuracy even in harsh industrial environments.
The 120 mm probe length configuration provides a versatile installation option suitable for medium-depth mounting requirements in a wide range of rotating machinery systems.
The product belongs to a globally recognized industrial monitoring technology brand specializing in machinery protection systems, vibration analysis, rotor dynamics, and predictive maintenance solutions.
Its technologies are widely applied in industries such as power generation, oil and gas, petrochemical processing, mining, steel manufacturing, marine engineering, and heavy industrial operations.
The brand is known for delivering high-reliability sensors designed for continuous operation in harsh industrial environments.
The 330881-28-08-120-00-02 is part of the 3300 XL 8 mm proximity transducer system, a widely used industrial platform for shaft displacement monitoring.
This system includes proximity probes, extension cables, and signal conditioning modules that work together as a complete measurement chain.
The series is known for high accuracy, excellent linearity, strong electromagnetic interference resistance, and long-term stability in continuous operation.
It is widely used in machinery protection systems to monitor vibration, shaft movement, and mechanical condition of rotating equipment.

The 330881-28-08-120-00-02 provides stable and accurate non-contact measurement of shaft displacement in rotating machinery.
Its eddy current sensing technology enables precise detection of small changes in shaft position, supporting early identification of mechanical faults such as imbalance, misalignment, looseness, or bearing wear.
The 120 mm probe length offers flexible installation for medium-depth mounting requirements in industrial machinery.
The stainless-steel housing ensures durability and resistance to vibration, oil, dust, and temperature variations.
The probe is designed for continuous operation and delivers stable long-term measurement performance with minimal maintenance needs.
Its fast response capability allows real-time monitoring of dynamic shaft behavior in high-speed rotating equipment.
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 on the metal surface.
These eddy currents change the electromagnetic impedance of the probe system. The variation is converted into an electrical signal proportional to the distance between probe and shaft.
Since the system is non-contact, it eliminates mechanical wear and ensures stable long-term operation.
The 330881-28-08-120-00-02 is widely used in rotating machinery monitoring systems across industrial sectors.
Typical applications include:
It is especially suitable for applications requiring balanced probe depth and installation flexibility.
The 330881-28-08-120-00-02 provides reliable long-term measurement performance in demanding industrial environments.
