5. Product Description
The 330103‑10‑20‑10‑02‑00 proximity probe is engineered to deliver accurate and reliable monitoring of rotating shaft motion without direct physical contact. The underlying eddy current principle generates an electromagnetic field at the probe tip. As a conductive shaft moves within this field, changes are detected and converted into a voltage signal proportional to the shaft’s displacement.
This signal is routed via the 1.0 m coaxial cable to a monitoring or protection module for analysis. With its 200 mm extension body, this probe can be installed in deep or recessed mounting locations. The rounded potted cable and connector provide secure connectivity suitable for industrial environments prone to vibration and temperature variations.
The probe’s construction is designed to withstand exposure to industrial dust, oil mist, vibration, and temperature changes without sacrificing measurement stability or reliability.
6. Applications
The 330103‑10‑20‑10‑02‑00 is suited for use in a variety of industrial rotating equipment, including:
- Steam turbines – measurement of radial and axial shaft motion.
- Gas turbines – monitoring rotor dynamics and vibration.
- Large centrifugal compressors – detecting imbalance and misalignment.
- Industrial pumps – vibration and shaft position detection for pump health.
- Electric motors – rotor condition and vibration monitoring.
- Gear reducers – assessing shaft movement under load.
Measurements enable early detection of faults such as imbalance, misalignment, looseness, or bearing degradation, which supports predictive maintenance and prevents unexpected downtime.
7. Product Advantages
