TM-0013-SW is the display record system for a dust-explosion-proof type seismic monitoring system SW-52EX and standard seismic monitoring system SW-52ST. This display can be connected 3 systems, also can display and record the seismic information of 3 systems. It acquires waveform and can output after logical judgement (AND/OR/2 out of 3) against seismic alarm.
Features
SW-52ST/SW-52EX can calculate at real time modified mercalli seismic intensity scale(estimate value by PGA) and SI value, so called “velocity response spectrum”, which is one of the standards to express an earthquake's destructive power against structures by using built-in servo type accelerometer.
