Wireless Temperature Sensor Using Permanent Magnets
Researchers at Purdue University have developed a novel wireless temperature sensor that works in environments completely surrounded by metal. By incorporating a commercially available technology that detects changes in magnetic fields with temperature, this technology measures temperature remotely at long distances through thick metal plates without active components, such as transistors, in the high temperature region. Thus, this technology is useful to monitor components and areas where wired sensors are not practical due to rotating shafts, enclosed metallic environments, and the lack of maneuverable space. By obtaining temperature data remotely, the lifetime of mechanical components can be more accurately estimated and sudden failures can be detected sooner.
