The DATALOGGER DLN is a LOW-POWER measuring system for acquisition and storing of measuring data of different precipitation sensors.
• Up to 1 year data storage
• THIES Distrometer (LPM) connection
• SD card and USB connection
• Sensors for temperature and humidity connectable
• Charge controller integrated for solar panel
The Datalogger DLN records pulse-measuring-values from at most 2 precipitation sensors. A PT100 sensor and a humidity sensor can be connected, too. The instrument stores the data together with time and date, according to the set storage cycle.
In addition, or exclusively as well, the measuring data of a THIES Disdrometer with serial data output (LPM 5.4110.xx.xxx), can be recorded and stored.
The readout of the stored data is carried out directly via the RS232 interface, USB, or by an SD card. All essential parameters, such as date, time, station name, and storage cycle can be set via 3 buttons.
The instrument can be operated in mains-independent mode with battery supply. An integrated charge controller is suitable for the direct connection of a max. 20 W solar-panel.
Another feature is the potential-free extraction of precipitation sensor pulses via opto-coupler, such as for further processing via local control systems.
The Datalogger DLN is designed for indoor installation. In case of outdoor application an additional protective housing of a respective protection class is required.
