摘要： A torque transducer comprises strain sensing means on a torque deformable shaft and slipring means for transmitting the torque signals from the rotating shaft to stationary brush means. The slipring means are annular discs of carbon material, such as sintered graphite, and the brush means are individual strips of flexible metal passing under tension partially around the respective slipring discs. The electrical contact between the strain sensing means and the carbon discs is by means of a number of printed circuit boards each of which has an annular or substantially annular portion with its conductive coating in face-to-face contact with a face of a respective carbon disc. The carbon discs and printed circuit boards being in axial compression on the shaft.

摘要： An angular motion detector, of particular relevance in breakaway point detection, includes a flywheel (1) rotatably mounted on a spindle (2). The flywheel (1) is provided with one or more indicia (7), which are detectable by a sensor (8) situated on the object whose angular motion is to be analysed. The sensor (8) is connected to a microprocessor (9). In use the flywheel (1) is rotated manually about the spindle (2) so that the regular detection of the indicia (7) by the sensor (8) causes a train of pulses to be sent to the microprocessor (9). Angular movement of the object, and consequently of the sensor (8), causes a disruption of the pulse train which can be analysed to provide information relating to the time of first movement and the magnitude of the angle moved.
