DAN Wireless Transmitters and Receivers are designed for a wide range of applications in process variable measurement and data transfer. When distance between the probe and the logging unit, or site conditions make hard wiring difficult or impractical DAN wireless connections offer a unique and convenient solution. Typically the range between a transmitter and receiver can be up to 2 kilometers depending upon the terrain and the obstructions and the antennas used at each end. With the use of selected antennas, the range may in some cases be extended to 10 kilometers.
