EXTERNAL SYSTEM CONTROL SEISMOMETER

S401-PSC★ Faster and better !
●S401-PSC calculates seismic intensity every
0.01s by adapting ‘’real-time seismic intensity
calculation method’’.

★ Simple and compact !
●●S401-PSC contains integrated sensors and processing unit, making unit small and compact.
Easy installation .

★ Various contact control！
●●

Individual output contacts setting allows precise
and flexible control for user’s application.
Real time control function (acceleration value,seismic intensity).

★ High reliability！
●

Improved measurement precision by adding 2
more outside sensors.

★ Extensive remote control and operation！
●●The data is set, obtained and displayed by PC
through web browser.
User will notice real time seismic information on
PC display.

★ Wide measurement range！
●●

S401-PSC measures up to ±6G.
2G, range setting is also possible for detailed
measurement.
