Abstract
Temperature measuring device for measuring the temperature of a member, the member including a component controlled by a control signal, active at most during at least one limited activity interval, and transmitted to the component via two wires, a temperature probe connected to the two wires, in parallel with the component, and a diode, connected between a terminal of the component and a terminal of the probe connected to the same wire, in order to allow the passage of a current in the component only in a first direction, the temperature measurement being performed by a current flowing in a second direction, opposite to the first direction, outside of the activity interval.
Claims20
A temperature measuring device (31) for measuring the temperature of a member (32), said member including a component (33) controlled by means of a control signal, active at most during at least one limited activity interval, and transmitted to the component (33) via two wires (34, 35), further comprising a temperature measurement means (50) connected to the two wires (34, 35), in parallel with the component (33), and a diode (51), connected between a terminal of the component (33) and a terminal of the measurement means (50) connected to the same wire (34, 35), in order to allow the passage of a current in the component (33) only in a first direction (S1), the temperature measurement being performed by means of a current flowing in a second direction (S2), opposite to the first direction (S1), outside of the activity interval.
