Seismometers

3S Seismometer
（SW-5033）

The industry’s first shock-resistant 1000G seismometer

A light, small, shock-resistant seismometer.
Simultaneous analog output of SI value (Kine) and acceleration (Gal) at the time of earthquake occurrence enables construction of a new network.

Features

Light, small and impact resistant

Compact size

Size has been significantly scaled down compared to a servo type acceleration sensor which had been generally used as a low frequency vibration measurement. Flexibility at installation site is improved.
Protection grade IP67

It is designed with a waterproof and dustproof protection and can be used outside safely.
Impact resistance 1000G

Having the high level impact resistance. The robust structure drastically reduce break accident in installation construction.

Accurate measurement of SI value and acceleration possible

With our uniquely developed capacitive acceleration sensor, we can accurately measure everything from insensitive earthquakes to strong earthquakes.

Low cost

Low cost has been achieved by specializing in the information and functions necessary for the local disaster prevention network in the event of an earthquake, such as analog output of SI value (Kine) and acceleration (Gal).
