A Study on TCal (Touchless Calibration): Contribution to Metrology for Industry 4.0

The unique concept of Touchless Calibration (TCal) was launched in 2018 as a contribution to the field of calibrations in Industry 4.0. A study, including explanations, results, uncertainties, and cost-benefit analysis, is described in this paper, followed by a practical experiment for the validation of TCal in the domain of DC voltage calibrations. On the XXII IMEKO Congress in Belfast in 2018, Touchless Calibration (TCal) was offered as a potential development in calibration metrology. TCal is primarily concerned with reducing the number of steps required to give calibration traceability. Missed steps actually contribute to a significant reduction in calibration time and costs while maintaining a high level of calibration traceability. It could be one of the most essential advancements in the scope of Industry 4.0, delivering increased efficacy and efficiency to the manufacturing industry.

This study shows that TCal can be utilised in manufacturing firms for the calibration of any measuring instrument used to measure DC voltages in the range of 0 V to 10 V with tolerances (USL – LSL) greater than 0.44825 V (0.022413 V) using worst-case scenarios.
