Furnace Control
(DCS, DiCS, PID, Invertion) Systems
|
|
|
| |
| ELIAR Industrial
Automation Unit has, to date, built many furnace control
systems, from single division furnaces where only the
temperature is controlled to furnaces where over 200 process
variables (temperature, pressure, oxygen, level, flow
etc) are kept under control. A Fully Automatic Spare Distributed
Intelligent Control Systems (DiCS) exists in these systems.
The most important aspect of DiCS's is the detection of
breakdown occurring in the system and replacing the defective
part automatically with the spare. |
|
These devices
placed in various locations of the workplace can be
monitored over the central monitoring computer and changes
in control values can be done. On the display of the
central monitoring computer, the process variables coming
from all devices connected to this computer can be observed
numerically or graphically on a mimic diagram. Furthermore:
|
| • |
All collected process variables are
recorded to the central monitoring computer. Those
records of the past dates and hours wished can graphically
be watched and sent to the printer. |
| • |
All collected data can be put into
an open database and data can be accessed by the
management information systems. |
| • |
Control parameter changes can be done
by accessing all control cycles over the computer. |
| The process can be monitored from
various locations in the workplace by connecting
monitoring computers to each other over the network. |

Batch Control
- Weighing with Raw Materials Recipe and Transfer Systems
|
|
|
| |
|
|
| The affecting factors
in the quality of a product most directly are the errors
made in the mix of raw materials. Therefore, the most
important aspects that ELIAR observes in the weighing
systems with recipe management are those: |
| |
|
|
| • |
Measurement sensitivity: The weights of
raw material should be measured with the highest
sensitivity possible. Therefore ELIAR uses the most
sensitive measurement techniques and devices that
today's technology provides. |
| • |
Weighing sensitivity: The weighing of
raw materials should be realized closest to the
aimed amount. Therefore ELIAR has developed special
weighing algorithms that adapt automatically to
changing aspects such as raw materials and humidification
and that get close to zero weighing errors. |
| • |
Reporting: Reporting is a must for both
the controlling of product quality, as well as
the raw material costs and follow-up on stocks.
Therefore, ELIAR weighing systems report all weightings
with time and grams and provides easy access to
the reports of management information systems
by storing them in an open database.

Data Acquisition
and Performance Systems
|
|
|
| |
• How much
raw materials have been used,
• How much energy and water been consumed,
• How much of the workforce been employed,
• Which tools have been used for how long,
• How much raw materials rest in stock,
• What breakdowns occurred in machines and how long
did the breakdown take,
• Are the process variables within limits in the
executed processes,
• In what line and for how long the products awaited,
• How many products have returned from quality control
and for what reason,
• Which machine is ready for maintenance,
• Which engine can have a breakdown soon,
• How many products are in stock,
• Are the warehouse temperature and humidity within
limits? |
|
Depending
on how fast you access these data and how easy you analyze
them, you can take right and fast decisions and bring
the productivity of the workplace to ideals with that
measure.
The losses occurring today due to lack of such data
collection systems in workplaces are a lot higher than
the costs of such systems.
Eliar Industrial Automation Unit is an expert unit in
collecting and analyzing data, storing in an open database
and sharing with management information systems.
