EPRO PR6423/003‑030‑CN Eddy‑Current Proximity Probe

EPRO PR6423/003‑030‑CN is an 8mm eddy‑current proximity probe used together with CON021 preamplifier unit. Based on eddy‑current measuring principle, it performs non‑contact measurement for shaft radial vibration, axial thrust displacement and shaft position of rotating machinery, converting gap variation into proportional voltage signal for machinery protection system.

This probe comes with 3‑meter integrated high‑temperature cable, features stainless‑steel probe housing and IP66 protection grade. It adapts to high‑temperature, high‑vibration bearing‑chamber environment, widely used as replacement spare‑part for on‑site troubleshooting, rotating‑machinery maintenance and retrofitting projects.
