Abstract
A load cell assembly, including an adapter adapted to receive a vertical load, and having loaded and unloaded dispositions a load cell body including a spring element having a first cutout window defined by a top beam and a bottom beam, the window transversely disposed through the body, the spring element adapted such that responsive to a downward force exerted on a top face of the adapter, the beams assume a primary double-bending configuration a strain-sensing gage, attached to the spring element, the strain-sensing gage for measuring strain in the spring element; and an at least two-dimensional flexural member having a second cutout window, the second cutout window being transversely disposed through the body; the adapter disposed in mechanical relation to the flexural member such that, in the loaded disposition of the adapter, the flexural member assumes a secondary, substantially double-bending configuration.
