A unit () for checking the dosing of pharmaceutical material (M) in a capsule filling machine () for the production of capsules (CF) of the type with a capsule lid (C) and a capsule body (F), the machine () comprising a fixed structure () fitted with a rotary drum () for supporting a plurality of capsules (CF) on its edge, opening each capsule (CF) by separating the capsule lid (C) from the capsule body (F), filling the capsule body (F) with a dose of material (M), then closing the capsule body (F) again with the relative capsule lid (C); the rotary drum () having a tank () containing the pharmaceutical material (M) and supporting a plurality of doser elements (), each comprising at least one piston () sliding inside a hollow cylinder () to pick up and compress a dose (DS) of material (M) from the tank () and discharge it into a capsule body (F) of a capsule (CF). The unit () comprises sensor means () attached to each piston () for detecting a piston () thrust value (V; V) on the dose (DS) and transmitter means () connected to the sensor means () for transmitting the value (V; V) to a receiver element () by the telemetric transmission of a relative signal (S; S), said receiver element () being fixed on the machine () in at least one zone (P; P) of the fixed structure (). Power supply means () are also provided for cyclically activating the sensor means () and the transmitter means () during drum () rotation.
