SIAP+MICROS Environmental Monitoring Solutions Since 1925 DATA ACQUISITION AND TELEMETRY SYSTEM DA18K Datalogger Low power consumption with high calculation capacity High flexibility Simple configurability, even remotely Long-term stability in harsh environmental conditions Automatic stand-by system for energy saving Wide range of analog / digital communication interfaces Analog inputs with 24 bit ADC Windows CE Operating System Standard Modbus RTU master / slave protocol

CARATTERISTICHE PRINCIPALI DA18K has been carefully designed for environmental and meteo-hydrological monitoring systems, in order to have a very versatile, reliable and powerful data logger with high standards of accuracy and precision. Sensors, analyzers, chemicalphysical probes, and many other devices can be easily connected to DA18K by means of a wide variety of analog and digital communication interfaces. Futhermore, the datalogger is equipped with serial and LAN ports that allow to interconnect communication systems such as radio-modems in free or licensed band (UHF, VHF, HF, SRD, ...),...

DISPLAY Instant data and data processed as average, minimum, maximum, data memory status, connection status, general status, operating system diagnostics, date and time. DATA PRE-PROCESSING (instantaneous measurements) • Data validation (plausibility check of the measure); • Data processing (for example: corrective formulas, calculation algorithms, application of forecast models). STATISTISTICAL ELABORATIONS (stored data) DA18K acquires the instantaneous values of measured samples and store it in a temporary file. At the end of a configured time period, and using the overall data, DA18K computes...
