Technical Specifications

Function and Working Principle

The 330101-00-15-15-02-05 utilizes eddy current technology to accurately measure the distance between the probe tip and a conductive target surface.

Operating process:

• The probe generates a high-frequency electromagnetic field.
• A conductive shaft or rotating component enters the sensing field.
• Eddy currents are induced on the target surface.
• Variations in the target distance alter the electromagnetic field strength.
• The system converts these changes into an electrical signal representing displacement.

This non-contact measurement method provides highly accurate monitoring without mechanical wear.
