MULTICOMPONENT-TRANSDUCERS: DEFINITION, CONSTRUCTION TYPES AND CALIBRATION CONSIDERATIONS

Daniel Schwind

Abstract

This paper summarises basic experiences of manufacturing and calibrating multicomponent-transducers (MCTs). Very often a diversity of the 'multicomponent' term is found, so at first a definition is given by using the vector item. <br />Because of the unlimited number of multicomponent applications, a graduation of types is difficult. Moreover there are main differences in construction resulting in different properties. Therefore the main construction principles of MCTs are discussed and an overview is given. Such information may be helpful for the choice of calibration equipment. <br />Regarding the properties of MCTs a diversity of terms is as often found. Especially the sensitivity to secondary components (sometimes called parasitic components), is often referred to as cross talk and mostly the exact definition is not clear. The terms are discussed and values to be indicated in a calibration certificate are proposed. <br />The calibrations of multicomponent transducers have been the subject of several considerations. Different methods of the standard equipment are discussed and a procedure is presented based on a force-vector-sensor as a transfer standard.
