ROTARY MEASURING DEVICE

摘要

A rotary measuring device which can measure the weight of an object more accurately by taking into account the error of centrifugal force more accurately. The rotary measuring device (1) comprises a measuring unit (20), a centrifugal force error calculation block (40), and a weight value calculation block (50). The measuring unit (20) has a measuring plate (25) and a load cell (27), and the load cell (27) has a fixed end (18) and a free end (17) for arranging the measuring plate (25). The centrifugal force error calculation block (40) calculates an angle displacement ? for the horizontal plane of the load cell (27) in the vicinity of the free end (17) based on a first measurement outputted from the load cell (27) under a state where the measuring unit (20) is rotating. The weight value calculation block (50) calculates the weight value of the object based on the angle displacement ?, and a second measurement outputted from the load cell (27) under a state where the measuring plate (25) is receiving the load of the object.
