DESCRIPTION

This article explores the innovative use of industrial PLCs, specifically Beckhoff models, for precise cryogenic control. It highlights the features such as high-precision temperature measurement using PT100 and LakeShore Cernox sensors. The system is capable of delivering temperature resolutions to 10mK for PT100 and under 1mK at 160K for Cernox sensors. With EtherCAT technology and a user-friendly graphical interface, this setup promises exceptional control loop stability and performance, overcoming challenges of cryogenic applications.
