5. Product Structure and Working Principle
The 330903-02-16-05-02-00 consists of a sensing probe tip, protective housing, integrated cable assembly, and electrical connection interface.
The working principle is based on eddy current sensing technology. When the probe is energized, it creates an electromagnetic field around the sensing tip.
When the rotating shaft changes position, the gap between the shaft and the probe changes. This variation affects the electromagnetic field, and the sensor converts this change into an electrical signal.
The monitoring system uses this signal to evaluate machine operating conditions and detect possible mechanical problems.
The non-contact measurement principle provides several advantages:
- No physical contact with rotating components.
- Reduced mechanical wear.
- Stable operation at high rotational speeds.
- Long-term measurement reliability.
- Suitable for continuous machinery monitoring.
