Lightning Prediction System



Code: P-251


AMEO 340 lightning detection system, by INEO, will anticipate lightning strikes within a 15 km radius of the sensor and warns the user of the possibility of a lightning strike and also indicates actual strikes.

AMEO 340 lightning detector measures the level and variations of the electrostatic field in real time. This information is processed by the control module that will activate the storm risk alarm and lightning strike alarm.

The probability of lightning strikes is linked to the electrostatic field in the storm cloud.
This value differs according to the local conditions:
- the geography viz altitude, geology of the land etc.
- the meteorological conditions viz hydrometry, aerology, pressure, atmospheric pollution.
- the keraunic level, the shape of infrastructure and orientation in the area.

The natural threshold of a lightning strike trigger point is approximately 5-8kV/m on plains and 9-17 kV/m in mountains. AMEO 340 gives warning before these threshold limits are reached within the 15 km radius.


AMEO 340 will provide a reliable lightning prediction, detection and warning system for:
- Sports stadiums
- Industrial plants
- Energy plants
- Transport
- Communication
- Mining

AMEO 340 is light and easy to install. The module is wall mounted and the sensor is externally mounted. The serial output of the measuring unit can be connected to a modem or a computer for the visualisation and recording (time stamping) of the electrostatic field evolution. Remote monitoring is possible.
