The capacitive probe (6) is of the type which has a probe housing (7) and a first plate (8), supported on the housing (7), which is designed to form with a second plate (41) a capacitor. The capacitor is connected to an electric voltage supply and the plates (8,41) are designed to be partially immersed in the liquid whose level is to be measured. The first plate (8) is mounted so that in can be adjusted between a first high measuring position and a second low measuring position. The plate (8) can be slid with respect to the housing (7) between the two positions. |
