The datalogger DLx-MET is a complete measuring system for the automatic data acquisition and storing of meteorological data (for ex. wind velocity, wind direction, temperature, precipitation, rel. air humidity,

radiation etc.).

The instrument is to be operated easily via three keys or via the serial interface COM 1 and USB.
A three-line alphanumeric display (LCD) serves as indicator. The instrument is supplied by an integrated 12V-battery, and the operation is completely mains independent thanks to the special low power design with respective solar panel and integrated solar controller. An integrated transformer offers the operation at 115 V / 230 V power supply.

Three serial interfaces and one USB offer – beside the communication – also the connection of sensors with respective operation modes (RS232 or RS285). An extension of the available measuring channels is possible by the optional connection of a so-called sensor interface. It is used to possibly connect additional sensors with standard current - or voltage output (4-20 m A/0-10 V) to the system. The sensor interface will be integrated in the datalogger housing.

The data memory of 2 MB capacity, and the real time clock (RTC) are buffered by the integrated lithium battery even in case of power failure. If necessary, an optionally connectable DCF 77-receiver provides a high-precision time synchronization in most European countries . An integrated SD-card interface for standard cards serves there for the data transport, where a communication infrastructure is not available.

The sampling of the measuring values is carried out by an high-precise AD converter with 24 bit resolution, and is adjustable from one second to 60 minutes. The measuring and processing rate can be activated or deactivated separately for each measuring value. The measuring values are written into the buffered RAM memory with storing rates selectable from 1 to 60 minutes for mean values, and from 1minute to 6 hours for extreme values. The reading-out of the data may be done via COM 1or by means of SD card. Plausibility controls on all measuring channels ensure highest quality and reliability of measuring data.
