DAM MONITORING SYSTEM
SYSCOM MR3003DMS seismic monitoring system is the most compact, integrated and reliable system for dams, ensuring highest level of safety and sustainability. Automatic earthquake detection and structural monitoring will ensure the full integrity of the dam over its lifetime.
MR3003DMS is extremely versatile and easy to install, thanks to its state of the art Ethernet master-slave connectivity and the command & control access through embedded web server.
Three relays output (alarm 1, alarm 2 and device error) can be directly connected to the dam control room for a centralized overview and an automatic logic response in case of any seismic event that might occur.
