SeTAC (SEQUOIA Triaxial Acceleration Computer) is a compact instrument that uses MEMS technology and that, when installed directly onboard the machine as an autonomous system, provides an innovative approach to triaxial vibration monitoring for applications in the safety, quality and process control fields.

Application :

  • Shock and collision monitoring
    The response speed of electronics specifically developed to recognise abnormal collisions and vibrations allows very low output times, with rapid machine stoppage and consequent reduction in damage (digital alarm triggered less than 1 millisecond from the start of the event).
  • Black box function
    The vibrations and collisions the machine is subject to are logged together with the date and amplitude of the event.
  • Unbalance detection
    The detection of an unbalance generates digital alarms when the preset thresholds are exceeded (on three levels).
  • Monitoring of specific mechanical parts or specific behaviours
    For instance, bearings, gears and chattering and resonance phenomena can be monitored.
  • Work cycle control
    The instrument can be integrated with the machine control chain using preset vibration thresholds that modify its behaviour.


  •     Compact design(30 x 55 x 15 mm)
  •     Protection class IP 67
  •     Built-in self-diagnostics able to guarantee correct instrument operation and measurement reliability
  •     Triaxial analysis with full scale of ±18 g per axis
  •     High precision of both high and low frequency analysis (from 0 to 2,500 Hz band)
  •     Ability to permanently store up to 12,000 vibration events, indicating the time and amplitude of phenomena
  •     Configuration with application software for PC suited to all types of application, thanks to specific algorithms aimed at recognising the phenomenon to be analysed
  •     Potential to set 3 digital alarms
