What is difference gap control ?
Answers
Differntial gap control is similar to on off control except that a band or gap exists around the control point.
USE : In industry differential gap control is often found in non critical level control polications where it is desirable only to prevent a tank from flooding or drying. When a measured variable exceeds the upper gap the control valve will open fully or be closed fully. Similarly when it exceeds the lower gap it will open or close fully.   Your Comment
