Abstract
The invention is a load cell for the measurement of force, independent of displacement, created by means such as weight, acceleration, pressure, and the like. The load cell has a beam structure with beams positioned parallel to each other in at least one plane. Generally, these parallel beams are attached to a stationary base and have sensing means attached between the two beams. In operation, deflection of one beam creates a response in the sensing means due to the relative action or deflection in the second beam.
