A packaging machine (1) for continuously producing sealed packages (2) of a pourable food product from a tube (4) of heat-seal sheet packaging material fed along a vertical path (A) and filled continuously with the food product by means of a fill conduit (8) extending inside the tube (4). The packaging machine (1) has a capacitive level sensor (14) located outside the tube (4) and in turn having a plate element (20) made of conducting material, positioned facing the fill conduit (8), and defining, together with the fill conduit (8), a capacitive element (22) whose capacitance depends, among other things, on the amount of food product between its plates. The level sensor (14) also has a detecting circuit (24) connected to and for detecting the capacitance of the capacitive element (22), and generating a level signal (SL) indicating the level of the food product inside the tube (4).
