Data logger SPA 170

The SPA170 is an affordable, low power and compact general-purpose data acquisition and logging unit.

  • Measures flexible set of parameters
  • Simple to use
  • High accuracy
  • Long autonomy with internal battery
  • Possible powering with alternative sources (wind, solar panels)
  • Internal data storage, expandable with SD memory cards
  • Accept all standard meteorological sensors
  • Communication over RS 232, RS 485, Ethernet, GSM/GPRS
  • Support FTP and Websocket protocols
  • Optional with touch LCD

SPA170 measures and calculates the following values: instant data, average value (in pre-set intervals), maximum (in pre-set intervals), minimum (in pre-set intervals), addition, etc..

At the end of each measuring interval, station stores measures and calculated data into its memory on a FIFO principle. Data are not lost if the station is powered off. Stored data can be reviewed or transmitted to the external computer. Much longer data storing intervals (up to several years) may be achieved using SD memory card. This card can be removed from the station and used as portable data-transfer media.

It has internal memory, 8 16-bit and 4 12-bit analog inputs, 13 digital inputs, 2 x PT100 (PT1000)  and 4 digital counters, all with the possibility of additional expansion and serial, mobile and network data transmission.
SPA170 electronics of the station is enclosed in a cabinet that can be, easily mounted on a standard mounting DIN rail.

Station can accept all standard meteorological sensors (temperature, relative humidity, atmospheric pressure, wind, ground temperature, precipitation, etc.). Other sensors (meteorological, hydrological, environmental, etc.) can be added. Meteorological calculations, such as evaporation, sunshine duration, etc., can be incorporated in the SPA170 software.

SPA170 has internal Flash memory, which can be enlarged by standard removable SD memory cards.

All configurations parameters can be set via RS-232 communications or Touch screen display (optional) and are stored in the internal memory.

SPA170 can communicate through RS-232, RS-485, Ethernet or GPRS/GSM module.
