Abstract
The embodiments relate to a method for detecting the temperature of a fluid flow of a control valve which has an electromagnetic actuator, in which a temperature-sensitive resistor is exposed to the fluid flow, and is integrated into a detection circuit. As a function of the fluid temperature, a primary circuit of the electromagnetic actuator is inductively influenced by the detection circuit.
