Abstract
Simple analog devices like manometers, manual valves, etc., have been ignored in the digitization process that has characterized the transition towards Industry 4.0. The reason behind this is that their substitution with the equivalent digital versions is high cost and needs re-wiring. This study introduces a low-cost wireless and passive model aligned with the Industry 4.0 paradigm to digitize analog indicators. The concept is based on electromagnetic (EM) shielding of the manometer’s embedded radio frequency identification (RFID) tag. We designed and tuned a new tiny RFID tag to be embedded into analog devices. Finally, a digitized manometer by RFID electromagnetic shielding concept is simulated in the Ansys HFSS modeling environment.
Highlights
The digitization process of raw materials, semifinished and finished products, and machines play a significant role in the Industry 4.0 revolution and rely mainly on the Internet of Things (IoT) and radio frequency identification (RFID) technologies
When discussing IoT applications in industry, we found the acronym IIoT that stands for Industrial IoT and that it is building a new domain with respect to IoT in everyday products
The RFID must be tuned precisely for its installation substrate simulation must be performed for all RFID tag, substrate, and metallic cover parameters [25,26]
Summary
The digitization process of raw materials, semifinished and finished products, and machines play a significant role in the Industry 4.0 revolution and rely mainly on the Internet of Things (IoT) and radio frequency identification (RFID) technologies. Manual valves, handwheels, levers, clamps, etc., are very common on shopfloors They are present in old machines, and in the piping system of modern plants, e.g., in fire extinguishers and in security elements such as cage doors, etc. Due to the slow evolution of the phenomena they monitor, they are left unread for a long time with possible consequences on safety (fire extinguishers), performance (wear and corrosion), and so on. Such oblivion is critical for the concept of completely twinning [2] the shop floor in order to be able to digitally manage the production (people and machines) in a cyber-physical way [3]
