„Delta-T Devices Ltd. GP1 Data Logger

  • High-precision 7-channel data logger
  • 600,000 record capacity
  • Free use of the DeltaLINK-Cloud data sharing service
  • Smart relay control

DeltaLINK-Cloud – a free online data service. The GP1 data logger is a complete logging solution housed in a waterproof IP67 housing with battery power. The internal memory can hold over 600,000 records – more than enough for one year (typical).
GP1 can register up to:

  • 2 differential analog voltages
  • 2 temperature channels
  • 2 pulse counters

In addition to being a powerful all-purpose logger, the GP1 is ideal for soil moisture measurements and can record:

  • 2 soil moisture sensors, such as ThetaProbes or SM150Ts
  • 2 temperature sensors
  • 2 pulse meters (e.g. rain or water meter)
  • 1 WET sensor

The optional GP-PBA-X50 Precision Bridge Adapter allows the GP1 to register up to 2 bridge sensors, such as pressure gauges and strain gauges.
When connected to 1 or 2 ThetaProbes or SM150T 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, using DeltaLINK software, can directly control irrigation from soil moisture (and/or rainfall and/or temperature) or act as a sophisticated interface between these sensors and various programmable timers.
Start and stop control levels can be configured separately, and there is even an option for pulsation when it is desirable to adapt the water delivery rate to the soil's absorption capacity.
PS: Our GP2 Advanced Data Logger and Controller offers even more advanced irrigation management capabilities.

DeltaLINK PC software

„DeltaLINK PC software is included free with all GP1, GP2 and DL6 data loggers. DeltaLINK allows you to set up the logger's input channels and recording parameters, check readings from connected sensors, and collect and display data.

  • Clear graphic display
  • Full configuration

Storage, communications and power

1 MB FLASH memory allows storage of 600 thousand records (typical). Data can be collected using a laptop directly via RS232 or via USB (USB-RS232 adapter cable required), or remotely using cellular modem options.
The GP1 has 1 PP3 internal battery as standard. Up to 10 GP1s can share power and communications using an M8 cable network system. GP2 data loggers can be integrated into such a network via an adapter cable.
