Abstract:
A stand free multi-beamed load cell for use in monitoring and registering weight changes, said multi-beamed load cell having:at least two beams, said at least two beams forming a rim surrounding an open center, said rim having a width and first surface, a second surface and depth there between;at least two tabs, said at least two tabs being positioned along said rim, each of said tabs being equally spaced along said rim from other tabs;at least two securing members, said securing members being approximately centered within each of said tabs and maintaining said second surface of each of said two tabs proximate a support surface;at least two pair of balance members, each of said pair of balance members extending beyond said second side plane of said tabs to maintain said load cell above said support surface;at least one bridge, said at least one bridge being a cavity within said beam to reduce said depth of said beam to enable said beam to flex under the application of weight to said first surface,at least one strain gage, said at least one strain gage being proximate said bridge to register the flexing of said beams,electronic connector means, said electronic connector means connecting said strain gage to control means,wherein said balance members minimize deflection on the tabs and rim proximate said tabs to create maximum strain level at said bridge and enable said tabs to accommodate for variations in the level of the support surface.
