4. Product Structure and Working Principle
The 330425-01-00 operates using eddy current sensing technology. The probe generates an electromagnetic field around the sensing tip. When the distance between the probe tip and the rotating shaft changes, the electromagnetic characteristics of the field also change.
The system converts these changes into electrical signals proportional to shaft displacement. The monitoring system analyzes the signal to determine vibration levels, shaft position, and mechanical operating conditions.
Because the probe operates without physical contact with the rotating shaft, it avoids mechanical wear and provides reliable measurement even when equipment operates at high speed for extended periods.
5. Main Product Features
High Precision Displacement Measurement
The product provides accurate measurement of shaft movement and vibration. It can detect very small changes in machine operation, allowing early identification of potential mechanical issues.
Non-Contact Measurement Design
The probe does not directly touch the rotating shaft. This eliminates friction-related wear and improves service life compared with traditional contact measurement methods.
Excellent Temperature Performance
The probe is designed to operate in industrial environments with temperature fluctuations, making it suitable for demanding rotating equipment applications.
Stable Measurement Signal
The product provides consistent output signals, supporting accurate vibration analysis and reliable machinery protection.
Compact Industrial Design
The probe features a compact structure that allows installation in limited spaces around bearings and rotating shafts.
High Reliability Operation
The probe is designed for continuous monitoring applications where equipment downtime must be minimized.
