Claims

[Claims for Utility Model Registration] (1) A system capable of detecting shear strain that occurs on the surface of a strain-generating portion formed on a rotating shaft connected between a rotary drive system and a load as the rotating shaft is torsioned. In a minute signal transmission device for a torque transducer that obtains an electric signal corresponding to torque using a bridge-connected detector including a strain gauge attached to the
an amplifier provided on the rotating shaft to amplify the output voltage of the torque converter; and an amplifier provided on the outer peripheral surface of the rotating shaft and electrically insulated from each other to apply a bridge voltage to the torque converter and output the output of the amplifier. and a slip ring mechanism for transmitting a signal to the stationary side, the minute output signal of the torque converter is amplified by the amplifier provided on the rotating shaft side, and then transmitted to the stationary side via the slip ring mechanism. A minute signal transmission device for a strain gauge type torque transducer, characterized in that it is configured as follows. (2) The amplifier is fixed to an annular substrate attached to the slip-ring mechanism so as to cooperate with other circuit elements or components to maintain rotational balance. Micro signal transmission device for strain gauge type torque transducer.
