Abstract

PURPOSE: To perform measurement with high accuracy by a simple construction, by providing two coils and two moving cores moving axially at the center of respective coils, and collecting the weight at the four corners to two corners, converting the result into frequency and performing measurement.
CONSTITUTION: The weigting stand 1 is provided with the levers 3, 3' via the blades 2, 2', the displacement of the levers 3, 3' is delivered to the link lever 6 connected with the moving core 8 to change the inductance of the coil L1. Further, this mechanism is placed opposingly left and right the base 4 of the measuring unit and the weight is collected as displacement every two corners at the levers of the four corners. Further, the change in the inductance of the coils L1, L2 is fed to the oscillation circuits OSC1, OSC2 gated with the outputs SG1, SG2 of the microcomputer CP1, and the displacement of the object is measured from the ratio of the frequencies. Accordingly, the measuring unit with a simple construction and stable for temperature change can be obtained with high accuracy.
