Disc type or annular load cell - has resilient element with props on one side carrying insulators supporting resistance strain gauges

摘要

The load cell includes a circular hollow housing (1) accommodating a resilient circular element (2) having a hemispherical lug (3) adapted to take up the load being measured eg a load suspended from a hoist. The opposite side of element (2) surface (4) has props (5) spaced from one another and arranged along two concentric circles. Props (5) have insulators (6) supporting resistance strain gauges (7). Element (2) is supported in housing (1) upon balls (8). The strain gauges (7) include a continuous wire arranged about the props (5) in sinuous fashion so that the spans of the resistance strain wire between successive pairs of adjoining props (5) are directed radially.
