Extremely flexible
The WXT520 is an extremely flexible product. Many of the sensors parameters, like sampling slot time and sampling interval, can easily be programmed to adapt the sensors performance to a large variety of different applications. At the same time its compact design makes it very easy to install and maintain. There are no moving parts that could be obstructed or damaged by birds, cobwebs or falling twigs. Its low power consumption makes it a good match for an Adcon RTU, to which it is connected via the A506 SDI-12 interface.
