FIELD: physics.
SUBSTANCE: digital torque wrench has a torque sensor whose input is connected through an amplifier to the data input of a first analogue-to-digital converter whose data outputs are connected to data inputs of a memory register, flip-flop whose R input is connected through a control button to a high-level voltage bus, and the output is connected through a display element to the common power bus, as well as a memory unit and a display unit. The invention is characterised by that the torque wrench has an angular sensor which is connected through a second analogue-to-digital converter to the memory unit which is connected to the write input of the memory register, the outputs of which are connected to inputs of the display unit. The R input of the memory register is connected to the R input of the flip-flop whose S input is connected to the output of the memory unit.
EFFECT: control of torque value when turning through a given angle.
