3. Product Introduction

The 330881-16-00-381-06-02 is an 8 mm proximity probe designed for high-precision industrial vibration and displacement monitoring.

It operates based on the eddy current principle, where variations in distance between the probe tip and a conductive target surface are converted into electrical signals.

The model is specifically designed for permanent installation in rotating machinery systems, providing continuous measurement of shaft behavior under real operating conditions.

The probe is built to maintain stable performance even under extreme vibration, temperature fluctuations, humidity, oil exposure, and electromagnetic interference.

Its construction ensures long operational life and stable measurement output in critical machinery protection systems.

5. Product Function Description

This proximity probe functions as the sensing element in a vibration monitoring system.

It continuously measures the distance between the probe tip and the rotating shaft surface. Any change in this distance caused by vibration, displacement, or rotor movement is converted into an electrical signal.

The signal is then processed by the monitoring system to evaluate machine health conditions such as imbalance, misalignment, shaft bowing, or bearing wear.

The probe is calibrated as part of a complete measurement system to ensure consistent and accurate results across operational conditions.
