Biral Thunderstorm Detectors are self-contained standalone devices that detect the presence of all forms of lightning including intra-cloud, cloud-to-cloud and cloud-to-ground. Additionally our sensors can warn of the risk of overhead lightning before the first discharge. The unique quasi-electrostatic operating principle developed by Biral ensures very high detection efficiency whilst maintaining a false alarm rate that is almost zero.

The BTD-350 Marine Thunderstorm Detector is a standalone sensor that reliably detects the presence of all forms of lightning to a range of 83 km. The unique quasi electrostatic operating principle gives the detector a very low false alarm rate and the ability to warn of the risk of overhead lightning.

The ability to reliably detect and range cloud-to-cloud lightning, which is typically much more common than cloud-to-ground strikes, makes the BTD-350 much more sensitive to the presence of storms compared to devices that rely on radio detection. The electrostatic operating principle allows the sensor to warn of the risk of overhead lightning before the first discharge occurs.

Virtually maintenance free in operation, the BTD-350 can either interface directly to an integrated system or be operated using the supplied PC compatible display and logging software. The optional warning relay module allows the sensor to automatically sound alarms whenever a storm approaches.
