EPRO CON021+PR6423/010-120 Eddy Current Measurement System

Overview

The EPRO CON021 + PR6423/010-120 system provides a fully integrated eddy current monitoring solution for rotating machinery. Combining a high-performance signal converter with a precision displacement and vibration probe, it delivers accurate non-contact measurements of shaft position, eccentricity, displacement, and vibration for turbines, compressors, pumps, and fans.

FAQ / Comparison

Q: Can the PR6423/010-120 probe be used with other CON021 variants?
A: Yes, it is compatible with most CON021 series converters and other PR642x series probes depending on the linear range and connector type.

Q: How does this system differ from PR6423/003-030?
A: The 010-120 variant provides a longer 12 m cable and mechanical configuration for larger setups, whereas the 003-030 has a shorter 3 m cable for compact installations.
