Measuring Device for Determining Physical Properties, Chemical Properties, Biological Properties and/or Materials in the Surroundings of at Least One Sensor or of the at Least One Sensor as a Component of the Measuring Device

摘要

The invention relates to measuring devices for determining physical properties, chemical properties, biological properties and/or substances in the environment of at least one transducer or of the at least one transducer itself as a component of the particular measuring device. The measuring devices are in particular characterised in that they are simple and robust to control and their function can be influenced. For this purpose, the measuring device consists of at least one transducer as a component of a passive device and/or as a component of an active measuring functional unit. The active measuring functional unit further consists of a data-processing system and a transceiver unit for electromagnetic radiation, and is interconnected to an electric power source. Furthermore, the transceiver unit of the active measuring functional unit is wirelessly connected to at least one transceiver unit, for electromagnetic radiation, of at least one passive device thatcomprises at least one operating element,comprises at least one switch,is designed for controlling the measuring device,is designed for signalling,is designed for obtaining measured values,is designed for displaying an operating state,is designed for calibrating the transducer,is formed as a data medium, and/oris formed as a data store.
