4. Product Structure and Working Principle
The 330908-21-35-10-02-00 works as a connection component within a complete proximity measurement system.
A standard proximity monitoring system includes:
- Proximity probe
- Extension cable
- Signal conditioning equipment
- Monitoring and protection module
The proximity probe operates using eddy current technology. The probe generates an electromagnetic field around the shaft surface. When the shaft moves, the distance between the probe tip and the rotating shaft changes.
This distance variation changes the electromagnetic field characteristics, which are converted into electrical signals representing:
- Shaft vibration amplitude
- Radial displacement
- Axial position
- Rotor movement condition
The extension cable transfers these measurement signals from the probe to the monitoring system while maintaining signal accuracy and stability.
The 10-meter cable design provides installation flexibility for large machines where the sensing point and monitoring cabinet are separated by a significant distance.
