Seismic Monitoring System “SW series” use the tri-axis servo acceleration pickup which can detect the minute earthquake.
With various functions, such as alarm buzzer or alarm external reset, it protects you from secondary disaster when the earthquake occurs.
The functions displayed by gray colour are excluded.

Features
-
[Fine Visual Display]
-
[Touch panel type]
Direct operation makes speedy conrirm.
-
[Easy fixing]
U-shaped fixing hole makes easy
anchor positioning for seismic
pickup and fixing. -
[System Calibration Service]
Calibration system is composed of a compact electrodynamic horizontal table PET-03 and an amplifier with oscillator PET-OA. It can simulate earthquake and enables an easy calibration test.
-
[Compact design]
By locating pick-up port at a lower place and rounding off the corners, we are able avoid impact to cables from outside.
-
[Water-proof type]
IP67 water proof compliant structure enables installation at
rainy or dusty places. -
[History Report Screen]
History up to 50 are saved.
-
[Safety and high accuracy]
This is the most advanced of all
electrical type. Servo sensors can
detect acceleration fromO Hz.
Three units of the servo type
sensors are equipped in a
seismometer to detect
accelerations in 3-axis.

Option
Options to expand the function are provided.
- Indicates Acceleration value, Seismic intensity scale and Alarm generation time.
“Color display in standard unit is a touch-panel display.
This optional external display is only an indicator without touch-panel function. - Takes out the alarm when 2-sets among 3-sets operate.
It increases the reliability of control･cut-off alarm contact output for seismic monitor.
