Overview

The EPRO PR6423/016-000 is a high-precision 16 mm eddy current displacement sensor designed for non-contact measurement of shaft vibration, axial displacement, and rotor position in turbomachinery. As part of Emerson’s AMS machinery protection platform, it delivers accurate and stable monitoring for critical rotating assets such as turbines, compressors, pumps, and large industrial machinery.

Moreover, the sensor’s large probe diameter enhances mechanical stability and improves measurement accuracy in heavy-duty applications. In addition, its rugged stainless-steel construction and IP66 protection rating allow reliable operation in harsh environments with high temperatures, vibration, contamination, and electromagnetic interference.
Therefore, the PR6423/016-000 is widely adopted in industries requiring predictive maintenance, machinery protection, and long-term operational reliability.
