EPRO PR6424/000‑100 Non‑Contact Eddy‑Current Probe Sensor for Rotating Machinery Condition Monitoring

Description

EPRO PR6424/000‑100 Non‑Contact Eddy‑Current Probe Sensor for Rotating Machinery Condition Monitoring

Product Details

The PR6424/000‑100 is a high‑precision eddy‑current displacement probe manufactured by EPRO (Emerson), widely deployed for turbomachinery protection systems. It is a 16 mm probe with 10‑meter standard extension cable, working cooperatively with CON021 signal converter (pre‑amplifier) to achieve non‑contact measurement. Based on eddy‑current induction principle, it converts shaft gap variation into linear analog voltage signal. The probe features stainless‑steel housing, good oil‑resistance and high‑temperature tolerance, suitable for long‑term installation near high‑speed rotating shafts. It complies with API‑670 machinery protection standard, outputs stable linear signal for TSI monitoring systems. Lemo connector ensures reliable connection with extension cable and preamplifier. This unit is commonly used as original spare‑part for steam turbine, gas turbine and compressor condition‑monitoring retrofitting projects.
