RFID in Explosion-Hazardous Areas: Three Examples from the Field
RFID: Noncontact identification based on radio waves is considered a versatile technology and one of the keys to production environments based on the Industry 4.0 principle. The range of applications is by no means limited to discrete manufacturing—RFID is also becoming increasingly popular in process plants due to the ever more extensive requirements for marking product and work equipment. However, explosion protection requirements often have to be taken into account, because wherever flammable gases, vapors or dusts are generated, electrical equipment poses a significant safety risk. In this blog article, you will gain insight into three application examples that will help you understand the successful and safe use of RFID in hazardous areas.
1. Reliable Detection and Protection of Hose Connections Using RFID
RFID read/write heads are mounted at the hose station in the immediate vicinity of the respective hose coupling.
Hoses are a universal work tool in the chemical and pharmaceutical industries, used to transport liquids, granules and powders. It is critical for process integrity and safety, as well as quality assurance, that hoses are connected only to their intended endpoints and that this connection is made reliably. An incorrect or unestablished connection can lead to safety problems, production downtime, significant cleaning effort or damage to the equipment with high consequential costs.
