Thunderstorm detector for long-range lightning warning, detecting cloud-to-cloud, cloud-to-ground and intra-cloud lightning up to 83 km, with quasi-electrostatic sensing, RS422 or Ethernet output and optional relays.
Sites with exposed people, assets or operations need lightning information early enough to act. The BTD-300 detects all forms of lightning out to 83 km and monitors local electric field strength and charged precipitation to warn of overhead strike risk before the first flash.
Its passive quasi-electrostatic principle measures low-frequency atmospheric electric field changes instead of relying on radio waves, giving high immunity to man-made RF interference and a false alarm rate below 2%. Detection efficiency reaches 95% for a single flash and 99–99.9% for storms with multiple flashes within 56 km.
Features
Quasi-electrostatic principle
The detector uses three antennas to measure low-frequency atmospheric electric field disturbances caused by lightning.
Lightning type detection
The system detects cloud-to-cloud, cloud-to-ground and intra-cloud lightning discharges.
Output and reporting
Ethernet or RS422 outputs provide self-test status, thunderstorm warning status, flash time, flash range and optional flash direction.
PC software
Supplied display and logging software supports local operation, monitoring and recorded lightning data.
Optional relays
The relay option provides three volt-free contacts for caution state, warning state and alert state.
Optional direction finding
The direction finder add-on reports lightning direction with 1° resolution, qualified by electrostatic ranging.
Configurable thresholds
Warning thresholds are user configurable to adapt the detector to site requirements.
Field test option
The optional battery Field Test Unit simulates lightning at different ranges for commissioning and routine checks.
