4. Product Working Principle
The 330400-02-RU uses eddy current sensing technology to perform accurate distance measurement without physical contact.
During operation, the sensor generates a high-frequency electromagnetic field around the probe tip. When the rotating shaft moves closer or farther away from the sensor, the electromagnetic field changes. The sensor converts these variations into electrical signals that represent shaft displacement.
The monitoring system analyzes these signals to determine vibration levels, shaft position changes, and possible mechanical problems.
The non-contact measurement method eliminates mechanical friction, reduces wear, and allows continuous monitoring of high-speed rotating equipment.
5. Product Design Features
High Accuracy Shaft Monitoring
The product provides precise measurement of shaft displacement and vibration changes. It can detect small variations in equipment operation, allowing early identification of mechanical problems.
Non-Contact Measurement Structure
The sensor does not physically touch the rotating shaft, which reduces maintenance requirements and improves operational reliability.
Excellent Signal Stability
The product provides consistent measurement signals during long-term operation, supporting accurate machinery analysis.
Industrial Grade Reliability
The sensor is designed for demanding industrial environments where equipment must operate continuously under vibration and temperature changes.
Flexible System Integration
