Details
This digital acquirer allows to acquire up to 30 channels (in the standard version, up to 60 channels optional) in multiples of 6, placed in a single cabinet with wall or floor fixing.
The communication system runs via LAN; the remote connection to the system can be made via 3G modem, 4G, FIBER OPTIC, WiFi.
The software DYMASOFT, integrated with the data processing software VIBROSOFT or SOLWEB, allows to realize efficient dynamic monitoring networks.
