Product Series
3300 XL Series
The 330930-040-03-00 belongs to the internationally recognized 3300 XL Series, a product family specifically developed for continuous monitoring and protection of rotating machinery.
The 3300 XL Series is engineered to measure important machine operating parameters including shaft vibration, shaft displacement, rotor eccentricity, thrust position, differential expansion, and shaft movement. The series consists of proximity probes, extension cables, Proximitor sensors, mounting accessories, and supporting components designed to operate together as a complete machinery monitoring solution.
Main characteristics of the series include:
- High measurement precision
- Excellent electrical stability
- Strong anti-interference capability
- Reliable long-term operation
- High compatibility among system components
- Flexible installation options
- Industrial-grade durability
- Stable signal transmission over extended cable lengths
- Suitable for continuous online monitoring systems
Product Introduction
The 330930-040-03-00 is designed to transmit analog signals produced by an eddy current proximity probe.
When machinery is operating, the probe continuously measures the distance between the sensing surface and the rotating shaft. Any change in shaft position modifies the electromagnetic field generated by the probe. These changes are converted into proportional electrical signals representing shaft vibration and displacement.
The extension cable transfers these signals to the Proximitor sensor while minimizing electrical losses and preventing external interference. High-quality shielding and precision construction ensure that the monitoring system receives accurate measurement data for vibration analysis and machinery protection.
Although the cable does not perform measurements directly, it is an essential component that supports the accuracy and reliability of the complete proximity transducer system.

Working Principle
The 330930-040-03-00 serves as the transmission path for electrical signals within the proximity transducer system.
The operating sequence is as follows:
- The proximity probe generates a high-frequency electromagnetic field.
- The rotating shaft influences this electromagnetic field as its position changes.
- The probe converts these variations into electrical signals.
- The extension cable transfers the signals to the Proximitor sensor with minimal electrical loss.
- The monitoring system processes the signals into shaft vibration, displacement, and position measurements.
Reliable signal transmission is critical because even small electrical disturbances may affect machinery diagnostics and protection accuracy.
