Product Description
Foxboro LMC211AE-MM Invensys I/A Series Level Measurement Controller
Product Overview
- The Foxboro LMC211AE-MM is a Level Measurement Controller from the Invensys I/A Series (now part of Schneider Electric's EcoStruxure Foxboro DCS). This device is designed to measure and control liquid levels in industrial processes, typically interfacing with level sensors and transmitting data to control systems via analog or digital signals. It is used in applications such as oil and gas, chemical processing, and water treatment for precise level monitoring and control. The MM suffix likely indicates a specific configuration, such as a mounting option or measurement mode.
