4. Technical Specifications

5. Product Description

The 330103‑10‑20‑10‑02‑CN proximity probe operates on the principle of eddy current sensing, where an electromagnetic field generated at the probe tip interacts with conductive surfaces such as shafts. Changes in the field due to shaft movement produce electrical signals proportional to the displacement.

The 10 mm tip diameter provides strong signal strength and good measurement resolution. The 200 mm case length accommodates installation in deep or recessed locations in machine housings. The 1.0 m cable provides flexibility for routing the signal to monitoring or protection systems.

The 02‑CN connector variant ensures secure mechanical and electrical engagement that matches regional industrial equipment interfacing standards. The IP67 protection rating ensures reliable operation even in environments exposed to dust, oil, moisture, and vibration.

This design provides long‑term stability, reduces maintenance needs, and supports high­accuracy condition monitoring that feeds into machinery protection or predictive maintenance systems.

6. Applications

The 330103‑10‑20‑10‑02‑CN proximity probe is suitable for a variety of industrial rotating machine applications, including:

• Steam turbines — monitoring axial and radial shaft movement.
• Gas turbines — providing real‑time vibration and shaft position data.
• Centrifugal compressors — detecting imbalance and misalignment.
• Pumps in processing plants — assessing vibration and clearance changes.
• Electric motors — detecting rotor imbalance or bearing wear.
• Gear reduction drivetrains — tracking shaft motion under load.

Monitoring capabilities include:
• Radial shaft vibration measurement.

• Axial or differential displacement detection.

• Shaft centerline position tracking.

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

These measurements support early fault detection and allow maintenance planning before catastrophic failure.
