Question:medium

Proportional band of an ON--OFF controller is

Show Hint

Gain ($K_p$) and Proportional Band ($\text{PB}$) are inversely related.
Because an ON-OFF controller acts with infinite gain ($K_p = \infty$) to produce immediate full-scale output changes, its proportional band ($\text{PB}$) is exactly zero.
