The 330881-28-08-070-03-02 is a precision industrial proximity probe designed for continuous monitoring of shaft vibration and displacement in rotating machinery. It is used in condition monitoring and machinery protection systems where stable, accurate, and real-time measurement of rotor behavior is required.
This probe is based on eddy current non-contact measurement technology. It detects the distance between the probe tip and a conductive metal surface without physical contact, allowing it to measure shaft position, radial vibration, axial displacement, and eccentricity with high accuracy.
Because there is no mechanical contact, the probe avoids wear and maintains stable performance over long operational periods. It is suitable for continuous operation in harsh industrial environments where reliability is critical.
The 070 mm probe length configuration provides a balanced installation option, making it suitable for medium-depth mounting requirements in rotating machinery systems.
This product belongs to a globally recognized industrial monitoring technology brand specializing in machinery protection, vibration analysis, rotor dynamics, and predictive maintenance systems.
Its solutions are widely used in critical industries such as power generation, oil and gas, petrochemical processing, mining, steel production, and marine engineering.
The brand is known for producing high-reliability measurement systems designed for continuous operation under demanding environmental and mechanical conditions.
The 330881-28-08-070-03-02 is part of the 3300 XL 8 mm proximity transducer system, a widely adopted industrial measurement platform for shaft displacement monitoring.
This system includes proximity probes, extension cables, and signal conditioning modules designed to function together as a complete measurement chain.
It is known for excellent linearity, high measurement accuracy, strong electromagnetic interference resistance, and long-term stability.
The series is commonly used in machinery protection systems for monitoring vibration, shaft movement, and mechanical condition of rotating equipment in real time.

The 330881-28-08-070-03-02 provides reliable non-contact measurement of shaft displacement in rotating machinery.
Its eddy current sensing principle ensures accurate detection of small shaft movement variations, enabling early detection of mechanical faults such as imbalance, misalignment, looseness, or bearing wear.
The 70 mm probe length provides a balanced installation depth suitable for a wide range of machinery configurations.
The stainless-steel housing ensures durability and resistance to harsh industrial conditions such as vibration, oil exposure, dust, and temperature changes.
The probe delivers stable long-term performance with minimal maintenance requirements.
Its fast dynamic response allows real-time monitoring of 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 metal target approaches, eddy currents are induced in the surface material.
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 surface.
This non-contact method eliminates mechanical wear and ensures long-term stable operation.
The 330881-28-08-070-03-02 is widely used in rotating machinery monitoring systems across multiple industries.
Typical applications include:
It is particularly suitable for applications requiring balanced probe length and installation flexibility.
The 330881-28-08-070-03-02 offers stable, high-precision measurement performance in demanding industrial environments.
