3.1. Diver dataloggers
Diver dataloggers are cost-effective and reliable instruments to provide long-term, frequent measurements of water
levels, temperature, conductivity and barometric pressure. Divers are ideal for monitoring municipal water supplies,
salt water intrusion, brine storage and migration and environmental monitoring of contamination and remediation
projects. A Diver contains an internal battery and memory. For more information on Diver dataloggers see the Diver
Product Manual.
3.2. DXT cable
The DXT cable is used to connect a Diver to the Diver-DXT. The DXT cable is mounted to the Diver-DXT housing
using a heavy-duty, water-tight connector that allows you to adjust the cable length as needed. This cable is
available in different lengths (up to 300 meters). For more information see Appendix II.
3.3. Diver-DXT
The Diver-DXT makes wireless communication possible. The Diver-DXT is placed on top of a well, while the Diver is
installed inside the well below the groundwater level. Both units are connected using a DXT cable, which acts as a
communication link and a mechanical link.
The Diver-DXT contains a low power short-range radio module. The radio module transmits radio signals at a
frequency of 2.405 GHz which is part of the unlicensed industrial, scientific and medical (ISM) radio band. The
transmission power of the radio module is 100 mW, 20 dBm resulting in a radio range of 500 m Line of Sight (L.o.S.).
Furthermore a network identification or network ID is setup in the radio module of the Diver-DXT to ensure the
security of the data and to give the option to create groups of DXTs (for example in areas where more than 1 Diver-
Gate(S) are able to communicate with 1 or more DXTs).
In order to minimize the battery use the radio of the Diver-DXT is deactivated during shipment to the client. The
radio will automatically activate (turn on) when the Diver-DXT is connected to a Diver via a DXT cable. The clock
