What is difference gap control?


#1

Differential 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 applications where it isdesirable only to prevent a tank from flooding or drying. When a measured variable exceeds the upper gapthe control valve will open fully or be closed fully. Similarly when it exceeds the lower gap it will open orclose fully.
