5. Product Structure and Working Principle

The 330903-00-06-10-02-05 consists of a sensing probe tip, housing structure, integrated cable assembly, and connection interface.

The probe operates using eddy current technology. During operation, the probe generates an electromagnetic field around the sensing area. When the rotating shaft position changes, the distance between the shaft and the probe tip changes, causing variations in the electromagnetic field.

These changes are converted into electrical signals that represent shaft movement. The monitoring system analyzes these signals to identify abnormal operating conditions such as:

• Excessive shaft vibration.
• Rotor imbalance.
• Mechanical looseness.
• Shaft misalignment.
• Bearing degradation.
• Abnormal machine movement.
