Lightning strike counter: CDR-11

Lightning counter CDR-11

Electro-mechanical lightning discharge counter.

The CDR-11 lightning discharge counter is a device designed to detect lightning strikes on external lightning protection systems (air terminals, ESE lightning rods, passive systems, etc.).

REQUEST MORE INFORMATION

The CDR-11 detects the electric current conducted to ground through the down conductor when a lightning strike occurs. The device records each strike by increasing the electromechanical counter by one unit. The CDR-11 is installed on the lightning rod down conductor and requires no external power supply, as it uses the lightning’s own energy for its operation.
