GP1 Data Logger

Ø  High accuracy 7 channel data logger

Ø  600,000 readings

Ø  Free use of DeltaLINK-Cloud data sharing service   

Ø  Smart relay control 

The GP1 Data Logger is a complete logging solution housed in a waterproof IP67 enclosure with battery power. The internal memory can hold >600,000 readings - more than enough for one year's operation (typical).
The GP1 can log up to:

Ø  2 ifferential analogue voltages

Ø  2 temperature channels

Ø  2 pulse counters
As well as being a powerful general purpose logger, the GP1 is ideal for soil moisture applications and can log:

Ø  2 soil moisture sensors e.g.ThetaProbes, SM300s or SM150s

Ø  2 temperature probes (or 2 further SM150 Sensors)

Ø  2 pulse counters (e.g.rainfall or water meter)

Ø  1 Delta-T  WET Sensor

Ø  Tensiometer input option using GP-PBA-X50
   The optional GP-PBA-X50 Precision Bridge Adapter enables a GP1 to log up to 2 bridge sensors such as pressure transducers and strain gauges and allows for the logging of up to two water-filled tensiometers. The bridge adapter is optimised for use with Delta-T Devices' SWT range of water-filled tensiometers but is compatible with many other bridge sensors.
    When connected to 1 or 2 ThetaProbes, SM300 or SM150 Soil Moisture Sensors, the GP1 Logger provides simple high accuracy recording of moisture content (as well as rainfall and temperature).

Irrigation control

The GP1 Data Logger, running DeltaLINK Software, can control irrigation directly from the soil moisture (and/or rainfall and/or temperature) or act as a sophisticated interface between these sensors and many types of programmable timer.

Start and Stop control levels can be separately configured and there's even an option for pulsing the output when it's desirable to match the water application rate to the soil's infiltration capacity.

NB: Our GP2 Advanced Data logger and Controller offers even more advanced irrigation control capabilities.
DeltaLINK PC Software
  DeltaLINK PC Software is supplied free with all GP1, GP2 and DL6 data loggers. DeltaLINK allows you to set up the logger input channels and recording parameters, check readings from connected sensors, and collect & display data.

Ø  Clear graphic display

Ø  Full configuration

Storage, communications and power 
1 Mbyte of FLASH memory enables storage of 600K readings (typical). Data can be collected by a laptop locally via RS232 or via USB (USB to RS232 Adaptor Cable type USB-RS232 required), or remotely using the GPRS modem options.

The GP1 has 1 PP3 internal battery as standard. Up to 10 GP1s can share power and communications using an M8 cabling network. GP2 Data Loggers can be integrated into such a network via an adapter cable.
