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.
The EXA ISC202G transmitter is a user programmable instrument
for conductivity measurements in medium to highly conductive
process liquids, using inductive measuring principles.
It is used in combination with the Yokogawa model ISC40
inductive conductivity sensor, for concentration monitoring
applications in the chemical industry and for various other
conductivity applications in the food and pharmaceutical industry,
the plating and metal finishing industry and pulp & paper industry.
The robust chromated cast aluminium housing, coated with a
Epoxy-polyester, makes it the ideal 2-wire transmitter for
mounting directly on-site, even under tough environmental
conditions. Its 2-wire concept gives low installation costs, a safe
operation and easy maintenance in the field.
The ISC202 features user-selectable process dedicated
temperature compensation for various (strong) acids and alkalis.
The process linearised output function and the "%"-concentration
displays contribute to a highly functional inductive conductivity
based concentration analyser.
FEATURES
- Process optimised temperature compensation to fit the instrument in any application.
- Extremely wide measuring range (> 6 decades) while maintaining a high resolution and accuracy using only one
sensor type : Minimum Conductivity 1.00 µS/cm
- Maximum Conductivity 2.00 S/cm.
- Free programmable setting of the output range, including a
21-step table to linearise the output function e.g. to weight%.
- Programmable % by weight display indication.
- Proven simple 3-level operation system using YES/NO
prompts where each level can seperately be protected from
unwanted access by a 3-digit passcode.
- Event logbook in software
