The BTD‑300 Thunderstorm Detector is a high‑performance lightning detection sensor designed for accurate storm monitoring and early warning of thunderstorm hazards. Its quasi‑electrostatic measurement technology detects all lightning types with a very low false‑alarm rate and provides overhead lightning alerts even before the first strike.
Unlike RF‑based lightning detectors, the BTD‑300 is immune to radio interference and offers a detection range up to 83 km, exceeding FAA aerodrome requirements. It meets EN 50536 and IEC 62793 standards, making it ideal for safety‑critical applications.
Built for harsh outdoor environments, the BTD‑300 features a robust, low‑maintenance design and supports flexible integration via Ethernet, RS422, or optional relay outputs. An optional direction‑finding module adds lightning bearing information for enhanced situational awareness.
