In dangerous and inaccessible application areas, where a cable based supply is nearly impossible or uneconomical, wireless radio technology finds its way into monitoring and controlling of industrial plants as an alternative solution. A provider of measuring and control technology Müller Industrie-Elektronik extended its range of wireless radio products in recent years. In addition to SI-FUE, more radio solutions were developed for transmission, recording and processing of measured values. Meanwhile energy efficient, high-performance and mesh capable radio solutions complete the portfolio. Because the radio units use 868 and 916 MHz frequency band with an operating distance of 300 m, they can be used globally. In addition the company offers a radio system for smaller ranges, using the license-free and globally used 2.4 GHz frequency band. For force measurement there are several solutions in combination with devices such as load, tension, load and compression load cells and load measuring pins to the point of wheel- and axle load platform scales for wireless radio transmission such as mobile digital strain gauge amplifier ADLM-HA, the new hand-held PC WPC-HA with integrated printing function, universal radio transmitter, USB radio receiver with applicable visualization and storage software for PC operation available. For the product group of digital indicators, modular ME sensor series and the new product line of DIN rail devices there are wireless radio solutions such as radio transmitter, DIN rail radio receiver, USB radio receiver and universal radio transmitter for visualization and processing of measured values available. Currently the company is working on a wireless radio solution for the ME sensor making the supply voltage for the radio transmitter available according to the energy harvesting principle. The required energy for the transmission of the radio signal can be provided by different physical measurements: at force measurement through movement or rotation originating vibration, at temperature and level measurement out of forthcoming ambient temperature or temperature difference. In this way the complex cable-based and high-maintenance battery supply can be passed on. Dangerous and inaccessible application areas, where a cable based supply is nearly impossible or uneconomical, can be wireless and battery-free staked by radio with the total process that way.
