Abstract
A calibrated load cell includes a monolithic load beam having a first region, a second region on a distal end of the load beam from the first region for receiving a force from a load, and a third region arranged between the first and second regions, wherein the third region comprises a recess on one side of the load beam. A strain gauge is arranged in the recess for detecting a deformation of the third region from the load and for generating a strain gauge output signal proportional to the deformation of the third region. The load cell also includes a microcontroller arranged in the recess for receiving and processing the strain gauge output signal to produce a load cell output signal that represents the load on a load cell output cable. The microcontroller transforms the strain gauge output signal based on calibration parameters to produce the load cell output signal as a calibrated load cell output signal.
