4. Technical Specifications

5. Product Description

The 330103‑12‑16‑10‑02‑05 proximity probe operates on eddy current sensing principles, where the probe emits an electromagnetic field from its sensing tip. Movement of a conductive shaft nearby produces changes in the field, which are converted into analog voltage signals proportional to displacement.

The 12 mm tip diameter provides a strong, high‑quality signal output, especially valuable in applications involving larger shafts or where higher signal amplitude is needed for clear measurement.

The 160 mm case length accommodates medium‑depth mounting into machine frames or bearing housings. The 1.0 m coaxial cable allows flexible routing to vibration monitoring or protection modules, while the 02‑05 connector ensures secure mechanical and electrical stability even in high‑vibration environments.

The probe’s IP67‑rated housing protects against dust, oil, moisture, and other industrial contaminants, ensuring long‑term, stable measurement performance.

6. Applications

The 330103‑12‑16‑10‑02‑05 is suitable for a wide range of industrial rotating machinery, including:

• Steam turbines — monitor axial and radial movement under load.
• Gas turbines — provide real‑time vibration and displacement data.
• Centrifugal compressors — detect imbalance, misalignment, and bearing wear.
• Industrial pumps — vibration and shaft motion monitoring.
• Electric motors — rotor vibration and position analysis.
• Large gear sets and reduction drives — dynamic shaft behavior tracking.

Typical measurement functions include:
• Radial vibration levels.

• Axial displacement measurement.

• Shaft centerline position tracking.

• Speed reference (Keyphasor) output for timing and phase analysis.

These capabilities support early fault detection, enabling predictive maintenance and reducing unplanned downtime.
