Abstract
PURPOSE:To perform high-precision weighing rapidly by obtaining a load in the form a digital signal directly without using any A/D converter by converting the load into a physical quantity regarding a rotational frequency or an angular velocity. CONSTITUTION:A rotary disk 7 for angular velocity measurement fixed to a prime power shaft 1 in one body rotates together with the prime power shaft 1 to transmit an angular velocity to a sensor 8 for angular velocity measurement fixed at a prescribed position. This sensor 8 is provided near the rotary disk 7, which is irradiated with light, etc.; every time the light is cut off by one of cut parts provided to the circumference of the rotary disk 7 at prescribed angle intervals, a pulse signal is sent to a counter 9. According to a reference clock signal from a reference clock generator 10, the counter 9 counts the pulse signal to output the number of the pulses, counted in a unit time, to an arithmetic part 1, which calculates an angluar velocity from a preset angle theta to calculate a load W applied to a driven shaft 2.
