BTD-300 THUNDERSTORM DETECTOR BTD-300 Thunderstorm Detector Standalone lightning detector giving range and direction data to FAA requirements … unique quasi electrostatic operating principle virtually eliminates false alarms Detects cloud-to-cloud and cloud-to-ground lightning Warns of overhead lightning risk Meets FAA performance requirements for aerodrome use Optional direction finder Highly immune to radio interference Very low maintenance requirements The basic sensor detects and ranges both cloudto-cloud and cloud-to-ground lightning. The ability to reliably detect and range cloud-tocloud lightning, which is typically much more common than cloud-to-ground strikes, makes the BTD-300 much more sensitive to the presence of storms compared to devices that rely on radio detection. As cloud-to-cloud lightning often precedes cloud-to-ground the sensor can give the user earlier warnings of lightning risk. The electrostatic operating principle allows the sensor to detect charged precipitation and the presence of strong electric fields, both of which are indicators of lightning risk. In this way the BTD-300 can warn of the risk of overhead lightning before the first discharge occurs. By monitoring the electrostatic field at very low frequencies rather than relying on radio wave detection the BTD-300 is almost immune to electromagnetic interference which is the major cause of false alarms for radio based detectors. Virtually maintenance free in operation, the BTD300 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. Biral have been manufacturing and supplying worldwide high specification Visibility and Present Weather Sensors since 1997. The BTD-300 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. email: met@biral.com
