5. Product Structure and Working Principle
The 330903-05-16-05-02-00 consists of a sensing probe tip, protective housing, integrated cable, and electrical connection interface.
The operating principle is based on eddy current measurement technology.
When the probe is powered, it creates a high-frequency electromagnetic field around the sensing tip. When the rotating shaft moves relative to the probe, the distance between the shaft surface and the probe changes.
This distance variation affects the electromagnetic field, and the sensor converts the change into an electrical output signal proportional to shaft displacement.
The monitoring system uses this signal to evaluate machine operating conditions and identify potential mechanical problems.
The non-contact sensing design provides:
- No direct contact with rotating parts.
- Reduced mechanical wear.
- Improved measurement stability.
- Reliable operation under continuous conditions.
- Long service life.
