The solution – using I/P signal converters for
valve position control
The solution to this problem is to use an I/P signal
converter as part of an open loop control system.
The converter regulates the position of a small
diaphragm valve with a 15 mm (0.59 in) stroke.
The valve controls the flow over a range
of 50 to 2,000 l/h (13.20 to 528.34 gph), with
an accuracy of ±3 to 5 l/h (±0.79 to 1.32 gph).
