EPRO PR6423/003-030 Product Introduction

Product Overview:

EPRO PR6423/003-030 is a non-contact eddy current sensor developed by EPRO (now part of Emerson) in Germany, specifically designed for monitoring shaft vibration and displacement in industrial equipment. This sensor is based on the eddy current effect and induces displacement changes on metal surfaces through high-frequency magnetic fields, providing high-precision dynamic signal output. It is widely used in real-time monitoring and protection systems for rotating machinery such as steam turbines, compressors, pumps, and gearboxes, such as the MMS3000/MMS6000 monitoring platform.

Main features and advantages:

High precision measurement: linear error ≤ 0.25%, temperature drift (zero point) ≤ 0.05%/K, time drift (zero point) ≤ 0.01%/24 hours, ensuring long-term stability.

Broadband response: The frequency range covers 5/10… 1000Hz (DIN45670 standard), supporting dual-mode output of vibration velocity and displacement.

Non contact design: avoids mechanical wear and is suitable for high temperature (-30…+80 ℃), high humidity (0… 95% non condensing), and strong electromagnetic interference environments.

Multi channel output: Supports two 0/4… 20mA current outputs or two 2-10V voltage outputs, compatible with analysis, diagnosis, and control system integration.

Anti interference capability: Complies with EN55011 and EN50082-2 standards, with built-in short-circuit/open circuit protection to ensure reliable signal transmission.
