Comprehensive Product Overview & Technical Guide (Offline Version)

1. Product Overview

The 330103‑10‑19‑05‑02‑CN is a high‑precision eddy current proximity probe designed for continuous, non‑contact measurement of shaft vibration, radial and axial displacement, and rotor position in industrial rotating machinery.

It belongs to the 3300 XL 10 mm proximity probe series, a widely used family of sensors in condition monitoring and protection systems for critical equipment.

The model designation (10‑19‑05‑02‑CN) describes the following configuration:

• 10 mm probe tip diameter, providing strong and consistent signal levels.
• 190 mm case length, suitable for deep mounting positions often encountered in industrial machinery structures.
• 0.5 m system cable for compact routing when long cable runs are not required.
• Connector variant “02‑CN”, indicating a regional (CN) industrial connector modification tailored to specific interface standards.

This proximity probe is engineered to deliver reliable and accurate measurement data under harsh operating environments, enabling long‑term machinery monitoring and proactive maintenance.

4. Technical Specifications

5. Product Description

The 330103‑10‑19‑05‑02‑CN proximity probe is designed for accurate, real‑time monitoring of rotating shafts in industrial machinery.

Using eddy current sensing technology, the probe emits an electromagnetic field from its tip. As a conductive shaft moves within this field, variations in the field are detected and converted into a voltage signal proportional to the shaft’s radial or axial position.

The extended 190 mm case length allows deep insertion into mounting bores or housings. The 0.5 m system cable allows compact routing to monitoring and protection modules within control cabinets. The CN connector variant ensures a secure mechanical and electrical connection tailored for regional industrial interface standards.

This probe delivers stable, long‑term performance even when exposed to vibration, oil mist, dust, and temperature changes. It is suitable for use in environments that demand high reliability and consistent measurement quality.

6. Applications

The 330103‑10‑19‑05‑02‑CN is widely used in industrial rotating machinery such as:

• Steam turbines
• Gas turbines
• Large compressors
• Industrial pumps
• Electric motors
• Gear reduction mechanisms

Typical monitoring functions include:

• Radial shaft vibration measurement

• Axial or differential displacement detection

• Shaft centerline position tracking

• Speed reference signal (Keyphasor)

These measurements support early detection of mechanical issues such as imbalance, misalignment, looseness, and bearing wear, enabling predictive maintenance and minimizing unexpected downtime.

7. Product Advantages

High Sensitivity and Signal Quality
The 10 mm probe tip provides strong and reliable output even in high‑load applications.

Non‑Contact Measurement
No physical contact with the shaft prevents wear and allows long service life with minimal maintenance.

Deep Mounting Capability
190 mm case length accommodates deep or recessed mounting positions in complex machine structures.

Compact Cable Routing
0.5 m cable length supports clean and manageable installation in control cabinets.

Secure Regional Connector
The CN variant connector provides reliable retention and connection suited to specific industrial standards.

Industrial Durability
IP67 sealed housing protects against dust, oil, moisture, and vibration exposure.
