GSM/GPRS DATA LOGGER RADIO

GSM/GPRS data Logger is a universal device used for the accurate measurement for applications. Thanks to the different configurable inputs of current, voltage, pulse or signal SDI-12, the Registrar supports the most popular sensors available on the market.

The device has been designed for use in agricultural, meteorological, hydrological, and industry related to the facilities where the precision, reliability and easy data access are key factors. Data constant transmission in intervals of minutes 1 or 10 is guaranteed by a modem GSM / GPRS embedded. All measurements are accessible through the intuitive web based data analysis system.

FEATURES:

- Data transmission GSM/GPRS at 1 or 10 minute intervals.

- 4 fully configurable inputs (0-3V, 0-10V, 4-20mA, Pulse counter)

- SDI-12 tickets for 4 additional sensors.

- User configurable alarms

- Software offline

4 configurable inputs

Possible configurations of 0-3V, 0-10V, 4-20mA or press counter.

Analog configurations

0-3V accuracy: ±(0.05% of reading +1mV), 0-10V accuracy: ±(0.5% of reading +1mV), 0-20mA accuracy: ±(0.5% of reading +10μA), 1-second sampling. Direct interface for potentiometer sensors.

Press counter configuration

- Frequency range - DC to 100 Hz.

- 3-second count integration.

- Special hardware filter for reed-switch closures.

Sensor power terminals

Each of the four sensor inputs is equipped with individual power Terminal

(SPW). The chosen voltage is switched on for 100ms (millisecond) before

each measurement.

SDI-12 input

One terminal for up to 4 measurements. By default the terminal voltage is

4V. Higher voltage up to 12V possible with the use of terminal SPW.
