1. Product Overview
330909-00-24-70-02-05 is a precision proximity extension cable assembly designed for use in industrial rotating machinery monitoring systems. It belongs to the 3300 XL Series and is mainly used as a signal transmission component between a proximity probe and a monitoring system.
The main function of this product is to extend the electrical connection distance between the sensor and the monitoring equipment while maintaining the accuracy and stability of eddy current measurement signals.
This model is designed for applications requiring reliable monitoring of shaft vibration, radial displacement, axial movement, and rotor position. It provides a stable signal transmission path, ensuring that measurement data from rotating machinery can be accurately transferred to the monitoring system.
The product features a 70-meter cable length, making it suitable for special industrial installations where the sensor location is extremely far from the monitoring cabinet or control room equipment. The extended cable design provides greater installation flexibility for large-scale industrial machinery.
The 330909-00-24-70-02-05 is commonly used in large rotating equipment such as turbines, compressors, generators, and other critical machinery where continuous condition monitoring is required.
It is designed for applications requiring:
- Long-distance signal transmission

4. Product Structure and Working Principle
The 330909-00-24-70-02-05 is used as an important connection component within a complete proximity measurement system.
A typical monitoring system includes:
| Component | Function |
|---|---|
| Proximity Probe | Detects shaft movement, vibration, and displacement |
| Extension Cable | Transfers measurement signals over long distance |
| Signal Processing Unit | Processes sensor output signals |
| Monitoring Module | Provides equipment protection and condition analysis |
The system operates using eddy current measurement technology.
The proximity probe generates an electromagnetic field near the rotating shaft surface. When the shaft moves due to vibration, thermal expansion, imbalance, or mechanical changes, the distance between the probe and shaft surface changes.
This distance variation affects the electromagnetic field and produces an electrical signal representing the shaft movement.
The extension cable transfers this signal from the sensor location to the monitoring system while maintaining:
- Signal accuracy
- Electrical stability
- Low transmission loss
- Reduced external interference
The 70-meter cable length provides special installation capability for large facilities where measurement points are located far away from monitoring equipment.
