4. Product Structure and Working Principle
The 330930-065-01-01 extension cable is installed between the proximity probe and the monitoring system as a signal transmission component.
A complete proximity measurement system normally includes:
- Proximity probe
- Extension cable
- Signal converter
- Monitoring module
The proximity probe measures the distance between the sensor tip and the rotating shaft surface using eddy current technology.
During machine operation, shaft vibration or displacement changes the distance between the probe and shaft. The probe converts these mechanical changes into electrical signals.
The extension cable transfers these signals to the monitoring equipment while maintaining measurement accuracy and signal stability.
The cable design helps minimize:
- Signal loss
- Electrical interference
- Transmission noise
- Measurement instability
This enables accurate monitoring of:
- Shaft vibration
- Rotor displacement
- Axial position
- Mechanical operating condition
