Virtual Pressure Measurement

Discharge pressure measurement is important in an extruder for various reasons.  Typically, melt pressure is measured just behind the breaker plate/screen pack at the screw tip for safety and process monitoring, and can also be measured beyond the screen pack for control purposes.
