What kind of feedback is used in DP cells?
In electronic DP transmitters there is no feedback. Field
sensors measure a physical phenomenon but do not use feedback.
Closed loop controllers use feedback (the process variable
reflecting the change in the controller's/final control
element output) and valve positioners use position feedback.
