Fieldbusses are based on highly reliable bi-directional
communications between “smart” field devices and HOST
systems. Next to a wide range of data each smart device can
provide their status which is essential for adequate control and
maintenance.
The famous EXA sensor diagnostics will provide
asset management facilities for those who operate and maintain
the plant.
“The advert of Fieldbus technology had made possible a wide
range of new capabilities throughout every level of the control
system that had not previously been possible or fully explored.”
Yokogawa has implemented three leading process Fieldbus
technologies in their 202 series: HART, Foundation Fieldbus H1
and Profibus PA. All transmitters are provided with the important
and widely used Device Description files that provide information
on parameters and other data in each device, as well as the
ability to include algorithmic relationships such as calibrations.
Flexibility, reliability and low maintenance are among the
benefits provided by the EXA SC202 conductivity analyzer.
Designed to meet the particular requirements of measuring
conductivity and resistivity in the modern industrial environment, it
contains many features to ensure the best precision whatever the
application.
The transmitter is housed in a robust IP65 field mountable case
and combined with the easy and clear LCD makes the SC202 a
complete industrial transmitter. The logbook can be used to
record events like calibrations and diagnostic messages. A wide
variety of temperature compensation possibilities (NaCl according
to IEC 746-3, manual TC, preprogrammed matrices and a free
programmable 5x5 matrix), provide a high-accuracy
measurement with a minimum effort.
The addition of a USP23
pure water monitoring feature also makes the SC202 suitable for
the pharmaceutical industry.
