the invention relates to a device for controlling charge of electrostatically charged ink drops.;it is composed of a load detector (100) together with an electronic circuit (12).the sensor comprises at least one inner cylinder driver (3) intended to be connected to a coaxial line (11) to an electronic circuit (12), the inner cylinder (3) is disposed concentriquemes compared with a hollow cylinder (1) connected to the external conductor of the mass (m) which is electrically insulated by an insulating sheath (2).a calibrated slot width and length (l) is carried out in such a way that it releases the passage through the detector for charged drops from in front of the inner cylinder (3)) induces a signal operated by the electronic circuit (12).;such a device can also be used to control the speed of the drops, including control means for pressurized ink to make the constant speed.
