• Proximitor monitoring module (signal processing unit)

The probe is the primary sensing component responsible for converting mechanical motion into electrical signals.

3. Product Introduction

The 330881-28-00-115-00-02 is an 8 mm proximity probe designed for high-precision vibration and displacement monitoring in rotating machinery systems.

It operates using eddy current sensing technology. The probe generates a high-frequency electromagnetic field, and changes in the distance between the probe tip and the conductive target surface (typically a rotating shaft) are converted into electrical signals.

This configuration includes a medium-length integrated cable structure (1.15 m section), providing a balance between installation flexibility and compact system integration.

The probe is designed for continuous monitoring applications in industrial environments requiring stable performance under long operational cycles.

It is built with stainless steel housing and industrial-grade insulation materials to ensure durability under vibration, oil exposure, humidity, and temperature fluctuations.

5. Product Function Description

This proximity probe functions as the primary sensing element in rotating machinery monitoring systems.

It continuously measures the distance between the probe tip and the rotating shaft surface. Any variation caused by vibration, imbalance, misalignment, or mechanical wear is converted into an electrical signal.

The monitoring system analyzes this signal to evaluate machine condition, including rotor stability, bearing wear, and alignment deviations.

The probe is calibrated as part of a complete system to ensure consistent and repeatable measurement accuracy.
