DATA ACQUISITION AND TELEMETRY SYSTEMCategories: Digitizer
DA18K has been carefully designed for environmental and meteo-hydrological monitoring systems. Sensors, analyzers, chemical-physical probes, and many others can be easily connected to DA18K by means of a wide variety of analogic and digital communication interfaces. Furthermore, 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, ...), GPRS modem, UMTS, LTE, router, satellite equipment (Iridium, Inmarsat, Meteosat, Goes, ..), and wired lines for remote connection.
DA18K is a forefront datalogger with very low power consumption, produced in Italy, and equipped with Modbus RTU communication protocol and Windows CE operating system. It is an extremely precise, robust and highly durable device, and it is suitable to be installed at any latitude, longitude and weather condition, from -40 °C to +80 °C, in every environment.
It can be configured and managed through wizard software, but it has been possible also to program customized applications using available open libraries, functions.
It supports any sort of monitoring sensors, communication systems, or high-level interfaces (for example: PLC, PC).
Product Detail Description
- Instant data and data processed as average, minimum, maximum, data memory status, connection status, general status, operating system diagnostics, date and time.
- Data validation (plausibility check of the measure);
- Data processing (for example: corrective formulas, calculation algorithms, application of forecast models).
DA18K acquires the instantaneous values of measured samples and stores it in a temporary file. At the end of a configured time period, and using the overall data, DA18K calculates the desired statistical parameters. For each measure, it's possible to define the time period and the statistical parameters. The main statistical parameters are: instantaneous value, arithmetic average, trigonometric average, vector average, cumulative, integrate, period, integral, vector average, trigonometric average.
STORAGE- Safety data storage in different areas in which are separately memorized instantaneous, statistical and alarms values); data could also be memorized on a removable memory;
- Memory management in linear mode (continuous storage up to full memory card capacity) or circular mode (data are rewritten if the memory card is full);
- Dynamic format structure for data transmission length optimization, this feature reduces the data volume allowing minor transmission times and minor communication costs.
- Data transmission by: modem, cellular phone, radio, satellite, serial cable RS232 or RS485 or mix connection;
- Data transmission as SMS (Short Messages System), e-mail, fax;
- Communication protocol TCP-IP, FTP, SMTP, MODBUS and MODBUS-TCP/IP, Store & Forward with control CRC MOD16.
The configuration software installed in DA18K operating system allows the user to configure all the data logger functions in the following ways:
- Local by means of a keyboard and/or touch-screen display or a USB terminal (notebook, tablet);
- Remote through the communication system or in web client mode.
DA18K has a set of procedures for the following checks:
- Verification of acquisition channel;
- Verification of memory capacity;
- Verification of communications performance;
- Verification of power supply blackouts.
- Unit of measurement of the sensor expressed in engineering units;
- Range: define minimum and maximum value registered by the sensor (lower and upper scale value);
- Decimals: number of decimals that define the measure;
- Conversion formula: mathematical formula to convert the input electrical signal into engineering units;
- Offset: define a measure offset (e.g. water level respect referring level).
- It's possible to define two alarm thresholds, one for minimum value and one for maximum value;
- In case of sensor alarm it's possible to send messages or SMS to configured phone numbers, define actions to undertake and re-entry modality.
