Yokogawa SC400-C-U-1-EA Conductivity Converter 2µS cm-500mSxC 0-20 mA DC 120VAC

Description:

The Yokogawa SC400-C-U-1-EA Conductivity Converter is used a 4-wire industrial analyzer designed for continuous measurement of conductivity or resistivity in liquid processes. It converts signals from a connected conductivity sensor into analog outputs (0–20 mA DC) for integration with PLC/DCS systems. The unit features a digital display, temperature compensation, and configurable ranges for stable and accurate process monitoring.

Applications:

The Yokogawa SC400 is used in industrial environments for continuous monitoring of conductivity and resistivity in liquid processes. It is commonly deployed in water and wastewater treatment, chemical processing, and power generation systems. The converter supports real-time measurement and control, helping maintain process quality, detect contamination, and ensure operational stability.
