Abstract
A load cell for weighing purposes which incorporates viscous damping inside a chamber in the body of the load cell. Specifically, symmetrical load cells have a central member which is where the load or weight is applied. This member is deflected under load as is common to all load cells, creating a distance change between said member and the static or fixed part of the load cell and in which the fixed part is used for mounting on a base holding the load cell. A round cavity or a cylinder space built into the static part accepts a piston which in turn is rigidly connected to the deflected part. Thus, upon loading, the piston has a slight movement relative to the cylinder. If a viscous fluid is then placed in the cavity such that the piston is immersed in it, a viscous damping will be achieved; its intensity depending on the fluid's viscosity, the geometry of the piston and cylinder, and on the load cell characteristics.
