PURPOSE:To measure the time change in weight of a deposited material accurately, by controlling the updating of a stored sample value based on whether the absolute value of the difference wth respect to the previous value of the weight of a sample stored in a register exceeds a specified value or not. CONSTITUTION:The weight of material deposited on a hopper is sampled and compared with the previous value of a sample stored in a register of an electronic computer. Only when the absolute value of the difference exceeds a specified value, the stored value in the register is updated by the sample value at this time. Therefore vibration of the hoppers, movement of a weight meter, or the like is not erroneously acknowledged as the change in weight value, and the time change in weight of the deposited material can be accurately measured. |
