In practice, many controllers have an input range and output range of 4 to 
.
. Suppose, at a certain setting of such a controller, the measured signal (input) varies from 10 to 
and in that case the output signal would vary from 10 to 
.
and in that case the output signal would vary from 10 to . The proportionality factor (K- factor) in this case is
, but the controller has an inverting effect (increasing current at the input causes the output current to decrease), so 
.
. The area of proportionality (that is that part of the output range, if used as input, that would change the output over 100%) is:
=33.3%.
