Deskripsi
Product Description
The EPRO CON021 signal converter paired with the PR6423/010-130 eddy current probe delivers a comprehensive solution for high-precision monitoring of turbomachinery. This combination enables non-contact measurement of shaft displacement, position, eccentricity, and vibration in steam, gas, and hydro turbines, as well as pumps, compressors, and fans. Engineered for reliability in harsh industrial environments, the system ensures accurate dynamic monitoring and seamless integration with Emerson MMS 6000 and IMR 6000 monitoring racks.
System Overview
The monitoring chain comprises:
Probe → Signal Converter → Rack/Monitoring System
The PR6423/010-130 probe features a 25 mm sensor head and a 13 m cable, providing flexibility for installation in large machinery. The CON021 converter processes signals with high accuracy and outputs standardized analog signals compatible with existing monitoring infrastructure.
