Abstract

The disclosure relates to a digital position transmitter for control of an actuating element having a positioner in a process installation, with the position transmitter having a regulator with a dead band in order to suppress disturbance signals. It is proposed that the dead band in each case lags the set-value change asymmetrically with respect to the set value.
