A level indicator is described for bulk material that includes at least one probe sensitive to its tilting with respect to the normal vertical position and at least one electronic control circuit having a first section, associated with the probe, and a second remote section connected to the first by means of a pair of conductors. The control circuit detects a signal of the current circulating between the two connected circuit sections and generates a processed signal representative of the position of the probe and the condition of the connection between the two circuit sections. |
