Why does a Calibration Class load cell have a base plate and a calibration adapter?
The calibration adapter and base plate help achieve all of these goals as shown in the diagram. In order to get high repeatability (low repeatability error) and low creep from a calibration class load cell Then the following conditions need to be met: • The cell sensing element must be mounted on a flat surface. • The load cell sensing element must be rigidly fixed to the structure. Rigidly fixed usually means bolted down. • The load cell element should be torqued down evenly to avoid distortion. • Any threads used in the loading path should be pre-tensioned to avoid thread creep during the load cycle. • All compressive forces should be applied absolutely perpendicular to the sensing element and any side loading should be avoided. • All tensile forces should be applied to the load cell absolutely perpendicular to the sensing element.
