Yokogawa Electric Corporation EXAxt450SC450G-A-U/UM Converter

The Yokogawa SC450G-A-U/UM EXAxt450 is a microprocessor-based conductivity and resistivity converter designed for continuous online measurement in industrial processes. It combines advanced signal processing, a touchscreen graphical interface, and integrated diagnostics to deliver accurate measurements and reliable operation, and it includes built-in PID control enabling it to function as both a measurement device and a process controller. The unit supports 2-electrode and 4-electrode sensors and provides dual 4–20 mA outputs with HART communication. Power typically 100–240 VAC (variant dependent), with an industrial, weatherproof enclosure suitable for indoor or outdoor installations and mounting options on walls, pipes, or panels. It is used in process control systems to measure conductivity, resistivity, and concentration in liquids, with common applications in water treatment plants, power generation, semiconductor facilities, and chemical processing industries for monitoring water quality and controlling dosing and process stability.
