Abstract

PURPOSE:To accurately measure weight by a method wherein the compression of a coiled spring is amplified, and the positional change of said amplified vertical movement is converted into an electrical signal. CONSTITUTION:When a load is applied to a weighing tray 3, a coiled spring 8 is compressed, and horizontal links 12a and 12b lower through a spring holding plate 9, a link 10 and movable rods 11a and 11b. The angles between a differential rod 16 and the horizontal links 12a and 12b vary freely, and the differential rod 16, a lever 19 and an iron core 20 are kept vertical at all times. The lowering of the horizontal links 12a and 12b is transmitted to the iron core 20 through the differential rod 16, an attaching member 18 and the lever 19, and a measurement output can be obtained from a differential transformer 21.
