MHV 117A measures wind, generating alarms at the excess wind speed. It is intended to be used on cranes, cable cars, bridges, roads, etc., where strong winds can be potentially hazardous.

MHV 117A consists of DHV 116 wind speed sensor, junction box with cable and connector, and MHV 117A electronic unit.

Both alarm levels can be set independently either for temporary or steady alarms. Each alarm has a potential-free relay contact.
