Abstract
The present invention relates to a method of analyzing accuracy of linear sensor output based on a theoretical prediction of the output model. The method comprises steps of: analyzing a statistically significant number of linear sensors to obtain operating profiles at two or more operating conditions; individually testing a linear sensor to obtain at least four data points; developing a theoretical prediction of the output model for each operating condition from the four data points; and comparing accuracy of the relationship between the theoretical prediction of the output model to sensor output in the operating profile corresponding to a given input for the same operating condition. Also disclosed are calibration algorithms associated therewith, as well as mechatronic units and further assemblies therefrom.
