4. Product Working Principle

The 330446-01-02-00 operates based on eddy current sensing technology, which enables accurate measurement without physical contact with rotating machinery components.

The probe generates an electromagnetic field around the sensing tip. When the rotating shaft moves relative to the probe, the distance change affects the electromagnetic field strength. The probe converts these changes into electrical signals proportional to shaft displacement.

The monitoring system analyzes these signals to determine:

• Shaft vibration level
• Radial movement
• Rotor position changes
• Mechanical operating stability

Because the probe does not contact the rotating shaft, there is no mechanical friction between the sensor and the machine component. This provides improved durability, lower maintenance requirements, and reliable performance during continuous operation.
