DATUM EF410 is a distributed digitizer adopting EtherCAT (Ethernet for Control Automation Technology) technology. The daisy chain design of DATUM EF410 allows on-site cable-saving for long-span infrastructures, such as bridges and reservoirs. Along with high signal to noise performance, DATUM EF410 is capable of integrating with high dynamic-range force balance accelerometers (FBAs). EtherCAT is also ideal for distributed time synchronization, fulfilling low drifting accuracy (≤1µs). The precision of time synchronization is mandatory for Structural Health Monitoring algorithms to be achieved in the on-site systems. Pairing with SanDAS (Sanlien Data Acquisition Software), it is able to display and record streaming data in real time and perform signal processing algorithms. More product specifications and site applications will be launched soon.
