DEVICE TO MEASURE TORQUE Russian patent published in 2013 - IPC G01L3/00 

FIELD: electricity.

SUBSTANCE: device to measure torque comprises a body, a sensitive element installed in the body on elastic supports, the first sensor of angular position of the sensitive element, a damper and elements of electric motor fixation. The device includes the second sensor of angular position of the sensitive element, the second DC amplifier. The damper is made on the first and second sensors of angular position of the sensitive element, the third DC amplifier and a current-to-torque converter. Amplifiers are used in the mode of current amplifiers. The first and second sensors of angular position of the sensitive element are arranged symmetrically and connected in series - in a coordinated manner one relative to the other. Speed sensors of the sensitive element are arranged symmetrically and connected in series - in a coordinated manner one relative to the other with an inlet of the third DC amplifier.

EFFECT: higher accuracy of torque measurement.
