BTD-350 – Long Range Thunderstorm Warning System

Senseca — Thu, 27 Nov 2025 16:40:18 +0000

The BTD-350 Thunderstorm Detector is a high-performance lightning sensor for reliable storm monitoring and early warning in demanding environments. Using advanced quasi-electrostatic measurement technology, it detects all lightning types with an exceptionally low false-alarm rate and can issue overhead lightning alerts even before the first discharge.

Unlike RF-based detectors, the BTD-350 is immune to radio interference and offers a detection range of up to 83 km, exceeding FAA aerodrome requirements. It detects cloud-to-ground, cloud-to-cloud, and intra-cloud lightning, as well as charged precipitation, and complies with EN 50536 and IEC 62793 for use in safety-critical, regulated applications, including marine and offshore.

Built for continuous outdoor operation, it features rugged, low-maintenance construction with high resistance to vibration, salt spray, and electromagnetic interference. Integration is supported via Ethernet or RS422, with optional relay outputs for local warning devices. An optional direction-finding feature provides lightning bearing information to improve situational awareness and response.

Key Features

Quasi-electrostatic lightning and thunderstorm detection
Early overhead lightning warning before first strike
Detection of all lightning types, including charged precipitation
Up to 83 km detection range
Immune to RF and man-made radio interference

BTD-200 Short Range Lightning Warning System

Senseca — Thu, 20 Nov 2025 14:28:03 +0000

The BTD 200 is a self-contained lightning warning system designed to provide early and reliable alerts of thunderstorm activity. Built on the same proven detection technology used in Biral’s professional aviation-grade systems, it identifies cloud-to-ground, cloud-to-cloud, and intra-cloud lightning, as well as charged precipitation and atmospheric electric field disturbances. This enables the BTD 200 to warn of overhead lightning risk even before the first strike, offering a level of protection not possible with radio-based detectors. With a 35 km detection range and a false alarm rate <2%, the BTD 200 delivers dependable situational awareness for outdoor safety and operational planning.

Key Features

Complete, ready-to-use warning system with simple installation
Early detection of overhead lightning risk before the first discharge
Detects all lightning types plus charged precipitation and strong electric fields
35 km detection range with proven professional-grade performance
Advanced automatic self-test ensures reliable system operation
Very low false alarm rate (<2%) helped by detecting low-frequency electric-field disturbances and filtering higher-frequency radio interference
Supplied with Lightning Works server software for monitoring, warning and data logging
Compliant with EN50536:2011+A1:2012 (Class 1) and performs in accordance with IEC 62793 (Class A)

Typical Applications

The BTD 200 is ideal for locations where accurate and early lightning warnings directly improve safety and operational continuity. Common applications include sports facilities, outdoor event venues, schools, leisure venues, industrial sites, construction areas, and professional meteorological installations requiring dependable, real-time thunderstorm alerts.
