SENSOR DEVICE

The current invention relates to a sensor device predisposed for installation in an electrical user.The sensor device (9) is suitable to detect both the presence and/or the level of a liquid in a containment compartment of the electrical user and the temperature of the liquid in the containment compartment. The sensor device (9) comprises at least a first sensitive element (7) capable of generating an output signal variable in relation to the presence or to the absence of liquid in the containment compartment and/or variable in relation to the level of liquid in the containment compartment. The sensor device (9) further comprises a temperature probe (8) capable of generating an output signal variable in relation to the temperature of liquid in the containment compartment and a support (10) on which the first sensitive element (7) and the temperature probe (8) are arranged. The sensor device (9) is configured to be applied outside a wall of the containment compartment.Additionally or alternatively, the sensor device is suitable to detect the presence and/or the level of a liquid in a containment compartment of the electrical user. The sensor device comprises a first sensitive element (7) of the capacitive type, a second sensitive element (77) of the capacitive type and an electronic control unit, operationally connected to the first sensitive element (7) and to the second sensitive element (77). The electronic control unit is configured to determine the presence or the absence of liquid in the containment compartment and/or the possible reaching of a predetermined level by the liquid in the containment compartment, on the basis of the difference between a first parameter (p) and a second parameter (s). The first parameter (p) is representative of the electrical capacitance of the first sensitive element (7), whilst the second parameter (s) is representative of the electrical capacitance of the second sensitive element (77).
