Thunderstorm Warning System TWX300

Vaisala Thunderstorm Warning System TWX300 uses real-time lightning information from Vaisala’s scientifically validated lightning detection networks in combination with on-site electric field mills and relays to monitor and warn on approaching thunderstorms and those that may develop overhead. Operations and safety managers rely on Vaisala’s Thunderstorm Warning System TWX300 to support safety goals, improve operational efficiency, and eliminate the subjective nature of ceasing activities due to lightning in the area of concern. TWX300 is designed for working environments that are most vulnerable to the hazards of lightning and need up-to-the second 24/7 lightning tracking, and automated lightning warnings including: Airports, Explosives testing, Mining and blasting operations, Munitions depots, Refineries, Sporting facilities and Outdoor events.

Field Mills

Up to 7 on-site Vaisala Electric Field Mills can be added to monitor overhead lightning potential. Vaisala Electric Field Mills measure the actual electrostatic charge in the local atmosphere to show when conditions are ideal for lightning to occur.

Remote Alarm Displays

Vaisala Remote Alarm Displays (RADS) display the warning levels in red, amber, and green LED arrays and sound 90 decibel audio alarms throughout a facility.

Relays

Connect a relay to the TWX300 system to turn on and off hardware such as lights and horns or message boards, to warn on impending lightning events.

Key benefits:

Proactive lightning risk management

Vaisala Thunderstorm Warning System TWX300 uses real-time lightning information from Vaisala’s scientifically validated lightning detection networks in combination with on-site electric field mills and relays to monitor and warn on approaching thunderstorms and those that may develop overhead.

Email notification of warnings and all clears

Combine data from the lightning network and the electric field mills to warn visually, via email, or through lights and horns connected to a relay when lightning discharges are detected or the conditions are ripe for lightning to occur.

Easy to use

Create multiple warning areas of any size or shape. Archive lightning data and create reports on historical lightning events Create videos of past lightning storms.
