SC450G Conductivity/Resistivity Converter
Brand: Yokogawa Electric CorporationThe EXAxt 450 series is designed to combine the superior functionality of the Yokogawa EXA series with the ease of use offered in pocket computers (PDA).
Truly unique is the EXAxt 450 series in the Human Machine Interface.
The high resolution graphical display and the touch screen operation make all information visible to the operator.
Configuration with the touch screen is as easy as operating a PDA.
Simply choose the language of choice and on screen instructions assure that the best configuration for the application is obtained.
The EXAxt 450 offers full functionality with PID control on either mA output(s) or on contact output(s).
The contact outputs can be selected as pulse frequency controlled or pulse length controlled contact function to control chemical metering pumps or solenoid valves.
