The TitanEA is a strong motion Ethernet accelerograph with power-over ethernet and Network Timing capabilities specifically designed for networked deployments on or in large civil structures such as nuclear reactors, multi-story buildings, bridges, and hydro-electric dams.

The TitanEA features the same Titan triaxial sensor and digitizer/recorder technology as the TitanSMA. The TitanEA comes in two models: the TitanEA Master has a GNSS receiver to get timing from satellites and acts as a network time master to supply timing over Ethernet to TitanEA Slaves..

Single Cable Ethernet Connectivity

Deploy the TitanEA in any structure with only a single Ethernet CAT5 cable for all functions: power, precision timing, data, and management. Ethernet connectivity eliminates the need to reroute expensive analogue cables throughout a structure and provides maximum flexibility in sensor placement.

Precision Time Protocol or Network Time Protocol

Precision Time Protocol (PTP) provides timing accuracy of <100µs:

  • No need for GNSS antennas at every sensor
  • Place the accelerograph anywhere in the structure
  • Time inputs provided through the single Ethernet connection
  • Network Time Protocol (NTP) permits the time source to be not on the same local LAN subnet.

    Structural Monitoring

    The TitanEA facilitates central control room monitoring of a structure, allowing operators to monitor the PGA, PGV, PGD, and SA of all sensors in the network, in real-time, on a convenient display.

    Each sensor in the network can be accessed independently using any mobile device with Internet access. Structural engineers can quickly view instrument status and events anywhere, anytime.
