4. Technical Specifications

5. Product Description

The 330103‑10‑20‑05‑02‑CN uses eddy current technology to provide non-contact, real-time measurement of shaft vibration and displacement. The probe emits an electromagnetic field from its tip, and movement of the shaft within this field produces a voltage signal proportional to the displacement.

Its 200 mm case length allows deep installation into machinery housings, while the 0.5 m coaxial cable ensures easy routing to monitoring modules. The CN connector variant is compatible with regional industrial standards and ensures a secure electrical and mechanical connection.

This probe is built for harsh industrial conditions, including vibration, dust, oil, and temperature extremes, ensuring accurate and reliable monitoring over the long term.

6. Applications

The 330103‑10‑20‑05‑02‑CN is widely used in:

• Steam turbines
• Gas turbines
• Large industrial compressors
• Pumps in petrochemical and power plants
• Electric motors
• Gearboxes

Monitoring capabilities include:

• Radial shaft vibration
• Axial displacement and shaft movement
• Centerline position of the rotor
• Keyphasor speed reference signals

These functions allow early detection of imbalance, misalignment, looseness, and bearing wear, reducing unplanned downtime.
