Intelligent Earthquake Sensor (Model:SES70)

Using the SES70 Intelligent Earthquake Sensor, the amount of damage caused by earthquake motion can be estimated. Additionally, this unit makes a judgment regarding ground liquefaction based on the acceleration waveform characteristics, and outputs the results.


  • 3-axis high-accuracy servo accelerometer
  • Measurement and calculation components to achieve a compact size at a low price
  • Calculation and output of seismic intensity (SI) and a value equivalent to the JMA shindo earthquake scale value
  • Output of liquefaction detection
  • Output of vibration detection
  • Output of error information through self-diagnosis of various its functions during operation
  • Casing with a pressure-resistant explosion-proof construction and an IP67 seal
