8. Working Principle
The probe works using eddy current displacement measurement technology:
- The probe emits a high-frequency electromagnetic field
- When the shaft moves closer or further away, eddy currents are induced
- These changes are converted into a voltage signal
- The system translates this into vibration or displacement data
9. Product Structure
The system generally includes:
- Proximity probe (this model)
- Extension cable
- Proximitor sensor (driver module)
