ATC990 Process Controller
The ATC990 Process Controller provides a cost-effective way to control a single process parameter, such as for a plastics extruder. Designed to improve user efficiency many features are integrated to reduce commissioning time, simplify operation and minimize maintenance downtime. Reliably auto-tune and alarm on strain gauge, DC voltage, temperature or current inputs. The ATC990 can also control differential pressure when an optional secondary strain gauge input is used.
- Auto-tuning control in a discrete 1/4 DIN package
- Graphical/text LCD Display with color change LED backlight on alarm (red/green)
- Graphical trend view of process, alarms & events as standard
- Easy to use Setup Wizard
- Single loop control
- Display and control of differential pressure is available
- USB port option for access to configuration and log files
- Data logging option logs process values, set points and alarms to .csv file for use with spreadsheets
- Modbus RS-485 and Modbus TCP Ethernet supported
- BlueControl configuration and commissioning software option

Tech Notes
The Importance of Monitoring Extrusion Stability
It has long been known that pressure instability for polymer melt entering the die usually results directly in output variation. Instrumentation used in these early studies was too delicate and expensive to be practical for routine commercial use. An excellent article written by B. H. Maddock, covering some of his early studies is title “Measurement and Analysis of Extruder Stability.”
