Industry 4.0 includes a wide variety of sensors to monitor different parameters along the process or to measure quality specifications, most of those sensors are electronically integrated to the process control. Some ISO quality standards require that “where necessary to ensure valid results, measuring equipment shall be calibrated” [3]. In this paper we present the current system that our Calibration Laboratory is using to calibrate the electronic measuring sensors, installed in the automated process of several smart industries. The aim of this work is to propose new technics for calibration, using the Internet and the worldwide network to provide a more efficient service and instant communication with the client. In the past, the calibration results were presented in paper or electronic documents. With the use of the new technics, the calibration results could be sent directly to the client data base, applying Metrology 4.0.
