Since the gravity level varies, also the load cell sensitivity varies by the location. Usual application for this load cell … Within our product family are numerous types of micro load cell that are ideally suited to applications where space is a limiting factor. In these types of load cells , the piston is usually kept in an elastic diaphragm but does not have a direct contact with the load cell. When classified by the direction of load detection, load cells can be divided into the following types: tension, compression, alternating, and bending. An Osterberg load cell was used in both load tests to provide end bearing and shaft friction parameters for the clay, clay till and clay shale bedrock. Bending beam or shear beam load cells are often used, for example, in platform scales.
