Suricat – 3D all-in-one digital accelerometer and velocimeter

SURICAT is a 3D digital accelerometer and velocimeter, equipped with GPS, designed for permanent installations on structures. Thanks to its small size (14 x 8 x 6 xm), it can also be used for the modal analysis of structures in full autonomy. SURICAT transmits the data via the 3G network (internal SIM card), via Bluetooth or via cable. In absence of a network, SURICAT stores the data in the internal memory until the network returns operative.

SURICAT is powered from an internal lithium battery that provides autonomy for a few hours. The internal microSD card can store data for several days.

SURICAT  is provided with the user-friendly Grilla software which allows to archive and analyze the recordings coming from the MOHO instruments:

  • Spectral analysis and cleaning
  • Modal analysis of structures
  • Vibration analysis
