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.
Claims16
A temperature measuring device (31) for measuring a temperature of a component (33) of a member (32), where the component (33) is controlled by means of a control signal for actuating the component, the control signal active at most during at least one limited activity interval and transmitted to the component (33) via two wires (34, 35), the temperature measuring device (31) 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), the diode (51) connected in series with the component (33) and in parallel with the temperature measurement means (50), the diode (51) configured to allow passage of current through the component (33) only in a first direction (S1),
- the temperature measurement means (50) configured to perform temperature measurement of the component by means of a measuring current through the temperature measurement means (50) via the two wires, where said measuring current flows at instants of time outside of the activity interval of the control signal and in a second direction (S2) opposite the first direction (S1).
