摘要： A torque transducing attachment (2) can be fastened to a air-driven impact tool (8) at its rear end. A shaft (20) in bearings (16) in a housing (12) has a torque transformable part (22) with integral bushes (24, 26) with apertures (29) on either side. The relative displacement under torque of the apertures (29) varies the amount of light transmitted from a stabilised LED source (36) to a photo detector (46) and the resulting signal is passed through frequency responsive network.

摘要： A torque transducer has a torque transformable shaft 2 with strain gauges 10, 12 electrically connected to sliprings 58 separated by spacers 60. A torque related signal is transmittable via the sliprings to a brush arrangement 22 having flexible strips 24 pulled by tension from springs 26 against the periphery of the sliprings 58, with the strips 24 tracked between the spacers 60 onto the sliprings 58.
