Epro PR6424/103-000 16mm Eddy Current Sensor

Applications

The PR6424/103-000 is widely deployed in condition monitoring architectures where continuous and accurate shaft movement data is required to support machinery protection and predictive maintenance strategies.

It is commonly used in steam turbines, gas turbines, hydro turbines, centrifugal compressors, pumps, and heavy industrial rotating equipment. In turbine systems, it provides real-time monitoring of radial vibration and axial shaft position. In compressor and pump applications, it supports early identification of mechanical degradation such as rotor instability, imbalance, misalignment, and bearing wear progression.

In power generation and process industries, it is typically integrated into API 670-compliant protection systems, where uninterrupted vibration feedback is essential to prevent operational excursions and equipment failure in high-value assets.

Advantages

This model is built on eddy current sensing technology, enabling accurate non-contact displacement measurement without mechanical wear or contact degradation.

It delivers stable linear response characteristics across its measurement range, ensuring reliable signal consistency even under high-speed shaft rotation. The 16mm probe geometry provides a stable electromagnetic field profile, improving repeatability across varying shaft surface conditions and installation configurations.

The PR6424 series is designed for industrial resilience, with strong immunity to vibration, thermal variation, and electromagnetic interference. Its long-term drift behavior is optimized for continuous monitoring environments, supporting extended calibration intervals and reduced maintenance demand in critical systems.
