Abstract

PURPOSE:To make the fixed end moments at both ends of a load cell body the same irrespectively of the working accuracy of a mounting base and to make installation work simple, by installing the load cell body to the mounting base by means of mounting fittings of simple constitution. CONSTITUTION:A load cell body is constituted of an intermediate part 2' acted with load G, and end parts 3a', 3b' which are located on both sides of the part 2' and are connected to the fixing side. In the part 2', strain gages 7a-7d are adhered in the thin walled parts 17a, 17b formed by punching of through-holes 15a, 15d and formation of a recess 16. Load G acts upon the central part 10' of the parts 17a and 17b via a lower spherical seat 11'. With such constitution, the fixed end moments at both ends of the load cell body are made the same simply by installing the load cell body to the mounting base by means of simple mounting fittings irrespectively of the working accuracy of the mounting base, and installation work is made simple.
