3. Product Introduction

The 330881-28-00-135-03-00 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 model features a 1.35 m integrated cable length configuration, making it suitable for medium-range installation requirements where both flexibility and routing control are important.

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

It is constructed with stainless steel housing and industrial-grade insulation materials, ensuring durability under vibration, oil exposure, humidity, and temperature variations.

5. Product Function Description

This proximity probe acts as the core 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 processes this signal to evaluate machine health conditions such as rotor instability, bearing wear, and alignment deviations.

The probe is calibrated within a complete system to ensure stable and repeatable measurement accuracy.
