ABSTRACT:
A multi-range load cell weighing scale includes a load receiving pan provided at the top of a casing, a high-range load cell disposed in the casing for a high range of weight determination, and a low-range load cell disposed in the casing for a low range of weight determination in a substantially horizontally juxtaposed relation to the high-range load cell. The low-range load cell has one end connected to one end of the high-range load cell. The other end of the high-range load cell is supported on the bottom of the casing, while the other end of the low-range load cell defines a load support on which the pan is supported. The load to be weighed bears on the two load cells simultaneously. The scale enables a wide range of highly accurate weight determination, despite its use of inexpensive load cells.
