Comprehensive Product Overview & Technical Guide (Offline Version)

1. Product Overview

The 330103‑11‑16‑10‑12‑05 is a high‑precision eddy current proximity probe designed for non‑contact measurement of shaft vibration, radial and axial displacement, and position in industrial rotating machinery.

It belongs to the 3300 XL proximity probe series, a globally recognized family of robust sensors used for machine condition monitoring, machinery protection, and predictive maintenance.

The model code (11‑16‑10‑12‑05) indicates the following:

• 11 mm probe tip diameter — offering high sensitivity and strong signal amplitude.
• 160 mm probe housing (case) length — suitable for medium-depth mounting.
• 1.0 m system cable — allowing flexible routing from probe to monitoring module.
• Connector option “12‑05” — industrial connector configuration providing secure mechanical and electrical connection, suitable for vibration-intensive environments.

This probe is built to deliver long-term, stable, and accurate signals under harsh industrial conditions.

4. Technical Specifications

5. Product Description

The 330103‑11‑16‑10‑12‑05 operates on eddy current sensing technology, where the probe generates an electromagnetic field at its tip. As a conductive shaft moves within this field, the variations in current produce an analog voltage signal proportional to the shaft’s radial or axial movement.

Key features include:

• 11 mm tip diameter for strong, precise signal output.
• 160 mm case length allowing installation in recessed machine locations.
• 1.0 m coaxial cable for flexible connection to monitoring systems.
• Industrial connector variant 12‑05 for secure mechanical and electrical engagement.

The probe’s IP67 housing ensures durability in dusty, oily, and high-vibration environments, supporting continuous and reliable machine condition monitoring.

6. Applications

Typical applications include:

• Steam turbines — monitoring radial and axial shaft motion.
• Gas turbines — measuring vibration and shaft displacement.
• Centrifugal compressors — detecting imbalance or misalignment.
• Industrial pumps — monitoring shaft movement and vibration.
• Electric motors — tracking rotor displacement and Keyphasor signals.
• Gear reduction drives — observing shaft dynamics under load.

Measurement capabilities:

• Radial and axial vibration detection.
• Shaft displacement tracking.
• Shaft centerline position monitoring.
• Speed reference/Keyphasor output for phase analysis.
