Abstract
A two-wire sensor (S) is connected to a pole via a first connection line (V ) in which a voltage longitudinal controller (SR) and a current-limiting resistor (R ) are positioned, and via a second connection line (V ) to which the other pole of a power supply source is connected. The output of the voltage longitudinal controller (SR) is connected to the second connection line (V ) via a first limiting diode (D ) and a second limiting diode (D ) which preferably is installed opposite the first connected diode. The joint node of the two limiting diodes (D D ) is connected to the control input of the voltage longitudinal controller (SR).
