Patent ID: 7756683

Claim:
A measuring device for measuring at least one environmental parameter, the measuring device comprising: a closed, thermally insulating casing; a central current supply; at least one sampling unit with an associated pump and one or more sensors; a data acquisition and processing unit having at least one signal processor for receiving the voltage signals of the at least one sensor and converting the voltage signals into voltage values, wherein the signal processor is coupled to a central processor for converting the voltage values into measured values of physical variables; a database including stored measured values of physical variables received from the data acquisition and processing unit; a long distance data transmission unit configured to retrieve measured values from the database and transmit the measured values over a long distance data connection; and wherein an interior of the casing is divided, in terms of thermal control, into a force-ventilated supply room housing the central current supply and a measurement room housing the one or more sensors and one or more subcomponents emitting waste heat, the measurement room provided with controlled measuring conditions and wherein the one or more sensors are thermally shielded individually from the measurement room via thermal insulation.
