Introduction

The PR6426/000-111 is a 32 mm eddy current proximity sensor used for precise monitoring of shaft displacement in large rotating machinery. It operates without contact, enabling accurate detection of vibration, eccentricity, and positional changes in industrial equipment.

The PR6426 series is widely used in turbine and compressor condition monitoring systems for critical rotating assets. According to manufacturer technical documentation for the PR6426 platform, the sensor is designed for large shaft measurement applications (≥200 mm shaft diameter) and supports high-stability monitoring in harsh industrial environments.

This makes it suitable for continuous monitoring systems where reliability and long-term stability are essential for machine protection and predictive maintenance strategies.
