Some considerations about choosing a method for Tcal

Abstract

The global trends in testing, diagnostics and inspections in manufacturing industry are strongly connected with development and implementation of Industry 4.0 framework. Two years ago, in the scope of initiative Metrology for Industry 4.0, the general idea for Touchless Calibration (TCal) was presented as a method for remote calibration of instruments in manufacturing industry. By implementing the TCal, instead sending the instruments, the companies will send only the Sensor/Transducer to the laboratory. Before that, in manufacturing premises they will provide Relative calibration. It is actually “pairing” (with other words: providing a ”mirror image”) of the Sensor/Transducer and Sensor/Actuators, without having the particular expensive standard (etalon). The method of transforming calibration data is actually determining the types and characteristics of Sensor/Transducer and Sensor/Actuators. Choosing a proper method, means not to increase the Type B uncertainties to the values which are comparable to the classical calibration. In this paper, authors will try to present some considerations regarding choosing a method based on transformation of calibration data into Time/Frequency which can be generated with extremely small uncertainties.
