Wireless process monitoring with RFID sensortags.

The demand of process monitoring is growing to the same extent as the level of automation. In order to avoid machine breakdowns or crashes, sensors are attached at critical points to monitor important process parameters such as temperature or mechanical stress. In practice, integration of sensors on rotating shafts or spindles is often not that easy, since cables or batteries can be integrated only with great effort. RFID sensortags are wire- and batteryless sensors, which simultaneously enables other functionalities such as counterfeit security or automatic part identification, even at operating temperatures above 100 °C.

Switchgears are the center of many industrial companies. Nowhere else start and end more cable routes than in control cabinets. All the more damage can be caused if the plants fail and cause complete production standstill. Undetected overloads, inadequate cooling or improper electrical installation can lead to effects such as arc flash and, in the worst possible consequence, to a fire emergence. Normally, thermographic examinations are carried out with infrared cameras in order to track down such thermal hot spots in the control cabinet, but continuous temperature monitoring is not possible with this technology. In addition, the investigation is often associated with the shutdown of the equipment for security reasons. RFID sensor technology enables uninterrupted, wireless and maintenance-free monitoring at all points in the control cabinet. Screw connections and other locations in the control cabinet can be thermally monitored.

Smart Manufacturing

Decentralized concepts for production control allow the control of various tasks directly by the workpiece. The Auto-ID technology RFID enables the automated and unambiguous identification of the workpiece. The workpiece, equipped with an RFID tag, not only carries the identification data but also production data, thus controlling the material flow without the need for other central units. This concept ultimately leads to self-sufficient production cells that can independently execute and regulate certain production steps independently of other units. The addition of wireless RFID sensor solutions significantly expands the spectrum of smart applications in production. At the same time, all the benefits of Auto-ID technology can continue to be used. For example, workpieces can be reliably identified, setpoints for the process can be stored on the RFID tag and temperature data on the workpiece can be determined during processing. Based on this data, the workpiece controls the process. The sensor data is e.g. used for direct regulation of furnace temperatures.

RFID has arrived in many logistics applications for a long time. The use of automated identification processes helps to simplify the traceability of goods across the entire supply chain and thus simplifies the inventory management of the individual parties involved. The combination of automatic identification and the acquisition of status data can generate additional benefits for manufacturers, service providers and customers. For example in the food industry or in the pharmaceutical industry, compliance with the cold chain is a very important issue. Tracking health conditions such as temperature and shock throughout the supply chain also allows new services to be generated. With RFID sensors, the status data can be tracked and stored wirelessly throughout the entire process.
