PURPOSE:To make it possible to measure weight with high precision by constituting the titled device by a generating part which generates the force corresponding to the weight, a signal converting part which converts the force into an electric signal a standard weight part consisting of a driving mechanism, and controlling part and performing zero adjustment and the calibration of sensitivity. CONSTITUTION:Saucer 2 acts as a generating mechanism which generates the force corresponding to weight W of the object 1 to be measured and parallel rink 3 acts as a power transmitting mechanism, which transmits the output from saucer 2 to oscillating body 4, and constitutes Roberval mechanism together with vertical lever 31 and horizontal levers 32 and 33. The oscillating part is secured pivotally to the intermediate part of lever 33 and the other end (h) is secured fixedly to base 17. Standard weight 5 is lifted up from saucer 6 or set up on saucer 6 according to the up-and-down motion of lever 7. Thus, weight can be measured with high precision. |
