3. Product Introduction

The 330881-16-06-165-07-02 is an 8 mm proximity probe designed for precise vibration and displacement monitoring in rotating machinery.

It operates based on eddy current sensing technology, where the probe generates a high-frequency electromagnetic field. Changes in the distance between the probe tip and the conductive target surface (usually a rotating shaft) are converted into proportional electrical signals.

This model is engineered for continuous monitoring applications in industrial environments where machinery operates under high load and continuous vibration.

The probe is designed for permanent installation, offering long-term stability and consistent measurement accuracy even in harsh conditions such as oil exposure, humidity, dust, and high temperatures.

5. Product Function Description

This proximity probe is a key sensing element in rotating machinery monitoring systems.

It continuously measures the gap between the probe tip and the rotating shaft surface. Any variation in this gap caused by vibration, shaft movement, or mechanical instability is converted into an electrical signal.

The monitoring system processes this signal to evaluate machine health conditions such as imbalance, misalignment, bearing wear, and rotor instability.

The probe is calibrated as part of a complete measurement system, ensuring consistent accuracy and repeatability.
