Abstract
A load cell having single or multiple resonators arranged to receive a strain that is proportional to the strain in a beam to which the resonator(s) is attached. Arrangement of the multiple resonators with respect to a force-bearing beam of the cell determines whether the cell is a bending mode load cell or a shear mode load cell. Absolute and differential pressure sensors, accelerometers and weighing devices are disclosed which employ the multiple-resonators of the invention.
