Ideal for Managing Critical Process Parameters

The ATC990 is a discrete, auto-tuning controller that is ideal for managing crictical process parameters such as polymer melt pressure or temperature on a plastics extruder. Standard inputs include strain gage, thermocouple or linear (dc-voltage or milliamps) and the unit can also control differential pressure when an optional secondary strain gage input is used. Other useful display inforamtion includes alarm set points, and error conditions.
