The Vaisala Thunderstorm Electric Field Mill EFM550 is designed to provide advance warning of overhead lightning threats by measuring the local atmospheric electric field. It features a measurement range of ±10 kV/m with an accuracy of ±5% of reading and a response time of 1 second. The device operates within a temperature range of -23 to +50 °C and can function in 0 to 100% relative humidity. The EFM550 integrates seamlessly with Vaisala's local-area lightning systems, such as the TWX300 and TSS928,Ñ¢, and can display data using the optional Vaisala ALARM software. It minimizes false alarms and requires no preventative maintenance for the first two years of operation, ensuring exceptional reliability. The product includes hardware for easy installation and flexible siting, making it suitable for various applications, including aerospace operations, hazardous material handling, and oil storage. The device operates on a voltage range of 100 to 240 VAC or 20 to 30 VDC, consuming 2.3 W of power.
Advance warning of overhead lightning threat
Vaisala Thunderstorm Electric Field Mill EFM550 integrates with Vaisala local area, real-time lightning systems to monitor the development and dissipation of overhead lightning threats by measuring the local atmospheric electric field. It also identifies when the threat has passed, providing valuable information to operations especially vulnerable to lightning. EFM550 data can be displayed using optional Vaisala ALARM Automated Lightning Alert Risk Management Software to show current electric field measurements numerically and graphically.
