nemi WAMS Bridge
nemi WAMS Bridge is the gateway in i4M's wireless Wide Area Monitoring System. It receives data from up to 30 wireless sensors at a distance of up to 1000 m and forwards the data to a server via 4G cellular connection - all with minimal energy consumption. nemi WAMS was developed for applications that do not require high data rates but coverage of sensors over long distances and long battery runtimes. This is made possible by i4M's own highly efficient radio technology nemi Link 868. The elimination of cabling enables easy installation even on large assets and structures. Examples for use cases are climate or crack monitoring on bridges or continuous temperature monitoring on rolling bearings in big production facilities.
