Seismic Monitoring System With Display
(SW-54 & SW-52)

A popular seismometer with display

SW-54 uses high-resolution servo accelerometers which can detect micro earthquakes.


Indication function

  • Importance level of information is shown by back color. It can be recognized even by remote watching.
    On earthquake ocurrence, “ocurrence time”, “peak acceleration”, “seismic intensity scale (measured seismic intensity)” are displayed.

  • 表示機能

Memory function

  • Up to 50 time histories can be saved.
    *Option software is needed to export waveform data.

  • メモリ機能

Alarm setting

  • 3-step alarm output by acceleration is possible. Alarm level is possible to be set.

  • 警報設定

Easy to operate

  • Touch panel is adopted. Easy operation makes speedy confirmation in an emergency.

  • 操作が簡単

Alarm setting

  • Compact size makes easy installation. It can be stored in a rack.

  • コンパクト

Waveform observation

  • By connecting with PC on which the option software is installed, various settings of the device and seismic waveform data stored in the internal memory can be acquired.

  • Waveform observation


Reliable accuracy

  • Built – in servo type accelerometer is also used for detection of micro-tremor. Both indication setting and alarm setting is 1 gal step.

  • 安心の高精度

Waterproof structure

  • It is ideal to install the seismometer on the common foundation to catch the motion of earthquake correctly. SW-72/72R adopts waterproof structure equivalent to IP67’s which is able to be installed outside or dusty environments.

  • 防塵Waterproof structure

Available to large-scale earthquake monitoring

  • The peak of motion in any direction can be surely captured by vector composition of the accelerations detected by the accelerometers arranged in three directions. The measurable acceleration range up to 5000 gal prepare against the large-scale earthquake.

  • 大規模地震にも対応

Easy installation

  • For the conventional seismometers, 4 points are requested to be fixed by anchor bolts. SW-72 or SW-72R has two cut-out holes for fixing bolts so that bolt position adjustment can be easier.

  • 設置が簡単

Compact design

  • In addition to the compact size, the cable port is located at the lower part and outer round shape to be surrond friendly.

  • コンパクト設計

External display

Indicates acceleration amplitude, seismic intensity scale and alarm occurence time.

Multiple control unit (2 out of 3) CU-5

Multiple control unit (2 out of 3) CU-5

This device makes reliability of the relay contact output of the alarm signal to control or stop activation higher. An alarm signal is output when 2 units out of 3 generate alarm signals.
