BTD-200 Lightning Warning System

The BTD-200 Lightning Warning System is a complete, out-of-the-box, self-contained sensor that reliably detects the presence of all forms of lightning to a range of 35km. The BTD-200 uses quasi-electrostatic measurements to avoid the problems associated with the detection of lightning using radio waves and to provide the ability to issue warnings prior to the first discharge of lightning.

The advanced detection principle of the BTD-200 enables it to monitor the strength of the local electric field and the presence of charged precipitation, both of which are strong indicators of lightning risk. This allows the BTD-200 to provide warnings of the risk of an overhead strike even before any lightning has been produced. This advance warning can be up to 20 minutes before the lightning begins, giving more than enough time to alert staff, members, teams and the public to the risks of remaining out of doors.
