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 field mountable
case. Two mA outputs, four relays, digital communication 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 with a
logbook facility in combination with the RS485 two wire
communication software option. 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 polaro-graphic
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.
