Pressure Control
Tight control of pressure improves both the quality of the product and the safety of the process. Dynisco's closed loop and differential pressure control algorithms are second to none. Call us or click the Engineer Button at the top of the screen to learn how you can improve quality, better protect equipment and operators, and decrease costs through improved control of extrusion pressure.
Closed-Loop Pressure Control
The ATC880 is a compact 1/4 DIN auto-tuning process controller that employs an acclaimed PID algorithm. The ATC880 is a cost-effective way to control a single process parameter, such as for a plastics extruder. Reliably auto-tune and alarm on strain gage, DC voltage or current inputs. The ATC880 can also control differential pressure when an optional secondary strain gage input is used. The bright 5-digit LED is accompanied by a helpful, quick view 35-segment analog bar graph. Other useful display information includes alarm set points, peak values, error conditions, and engineering unit beacons. The ATC880 is easily field-configured or programmed remotely via optional Modbus / Jbus without annoying mechanical jumpers. An optional 24Vdc input supply is also available.

Differential Pressure Control
The secondary input on the UPR 800 used to indicate differential pressure measurement by monitoring the relative pressure before and after the screen pack. The UPR includes two standard assignable alarms and the option to add a third. The bright 5-digit LED display value is accompanied by a helpful 35-segment bar graph that illustrates the value in the configured range. Other useful display information includes alarm set points, peak values, and engineering unit beacons. The UPR800 is easily field-configured or can be programmed remotely via optional Modbus RS-485 without complicated mechanical jumpers. An optional 24Vdc input supply is available.
