1. A method for detecting a fluid temperature of a fluid flow of a control valve with an electromagnetic actuator, the method comprising:
exposing the fluid flow to a temperature-sensitive resistor;
integrating the temperature-sensitive resistor into a detection circuit; and
inductively influencing, by the detection circuit, a primary circuit of the electromagnetic actuator, wherein the inductively influencing depends on the fluid temperature, wherein the detection circuit is configured to detect a power consumption change of the primary coil of the electromagnetic actuator, and to associate it to the fluid temperature.
