[ We claim:] [1.] A steam generator with automatic supply comprising:a heating tube (20) comprising a vessel (21) designed for containing a liquid (26), at least one heating element (5) of the vessel (21), able to vaporize the liquid (26), means (10, 15, 16) for tapping the steam (27) in the vessel

[ We claim:] [1.] A steam generator with automatic supply comprising:a heating tube (20) comprising a vessel (21) designed for containing a liquid (26), at least one heating element (5) of the vessel (21), able to vaporize the liquid (26), means (10, 15, 16) for tapping the steam (27) in the vessel (21),a device (1, 2, 17) to supply the vessel (21) with liquid (26),a level sensor (11) to measure the level of the liquid (26) in the vessel (21) and arranged in a zone (30) of the vessel (21) situated at a set threshold level, said level sensor (11) comprising heating means (13), capable of heating the said zone (30) and measuring means (12) to measure the temperature in the said zone (30) and to compare this reading to a reference temperature, in order to establish whether the liquid (26) has reached the threshold level,a supply control (2) actuated by the level sensor (11) and acting on the supply device (1, 2, 17), which delivers the liquid (26) automatically to the vessel (21) when the level of liquid (26) is below the threshold level and blocks the supply when the level of the liquid (26) is greater than or equal to the threshold level, andan adjustment means (44, 45) designed to act in response to the tapping of steam (27), so that the temperature of the level sensor (11) varies with respect to the level of liquid (26), over a variation range enabling comparison with the reference temperature, and wherein said reference temperature lies within the variation range.
