Yokogawa 4 Wire DO402G Converter

Flexibility, reliability and low maintenance are among the benefits provided by the EXA DO402G dissolved oxygen converter. Designed to meet the exacting requirements of measuring dissolved oxygen in the modern industrial environment, it contains many features to ensure the best precision whatever the application. This 4-wire converter is housed in a robust IP65, NEMA 4X, CSA Type 3S field mountable case. Two mA outputs, four relays and a clear LCD make the DO402G a truly comprehensive package. The DO402G features PI control on both the auxiliary mA output and the pulse proportional relay outputs, thus avoiding the need for a separate controller. The famous EXA sensor diagnostics are now expanded. This can be used to record events like calibration and diagnostic messages, and to update configuration of the converter remotely. The DO402G accepts inputs from both galvanic and polarographic sensors. Percent saturation, mg oxygen/l water, and ppm DO can be displayed and transmitted. Compensation for atmospheric pressure altitude, salinity and temperature are included for the best accuracy of measurement.
