Introduction of the seismic intensity meter

The seismic intensity meter has made it possible to observe the seismic intensity objectively, and the uninhabited observation has stepped up the establishment at various places.
And the automatic control has made it possible to decrease the time from the observation to the announcement.
Therefore, the introduction of the seismic intensity meter has various merits.



　　Measurement unit (accelerometer)：This unit observes the quake and changes it to
　　　　　　　　　　　　　　　　　　　　　the electric signal.
　　Processing unit ：This unit calculates the seismic intensity from the electric signal
　　　　　　　　　　　　and shows the result on the display.
