5. Product Description
The 330103‑12‑18‑05‑02‑00 operates using eddy current sensing principles. The probe emits an electromagnetic field from the tip; displacement of a conductive shaft within this field generates a voltage proportional to movement.
The 12 mm tip diameter delivers a strong, high-quality signal, while the 180 mm case length accommodates deeper mounting scenarios for larger machines. The 0.5 m coaxial cable is ideal for installations requiring short routing distance.
Its industrial-grade connector ensures reliable electrical contact, even under high vibration, and the IP67-rated housing guarantees long-term operation in harsh industrial environments.
6. Applications
The 330103‑12‑18‑05‑02‑00 is widely applied in:
- Steam turbines – axial and radial shaft vibration monitoring.
- Gas turbines – continuous rotor position measurement.
- Centrifugal compressors – detecting imbalance and misalignment.
- Industrial pumps – vibration and displacement monitoring.
- Electric motors – rotor displacement and vibration analysis.
- Gearboxes – monitoring shaft movement and bearing health.
This probe supports predictive maintenance, early fault detection, and machinery protection.
7. Product Advantages
