4. Product Working Principle
The 330908-00-40-05-02-05 operates using eddy current proximity measurement technology.
The probe generates a high-frequency electromagnetic field from the sensing tip. When the rotating shaft moves relative to the probe, the distance change causes a variation in the electromagnetic field.
The sensor electronics convert this variation into an electrical signal. The monitoring system processes the signal to determine shaft vibration levels, displacement changes, and machine operating conditions.
The non-contact design allows the probe to continuously monitor rotating equipment without physical wear caused by direct contact. This improves reliability and makes the sensor suitable for long-term operation in demanding industrial environments.

The probe provides accurate detection of shaft movement and vibration changes.
It allows monitoring systems to identify abnormal operating conditions, helping maintenance personnel perform preventive actions before equipment damage occurs.
5.2 Non-Contact Sensing Technology
The sensor operates without direct contact with the rotating shaft.
This eliminates friction, reduces mechanical wear, improves measurement consistency, and extends the service life of the monitoring system.
