Seismic Alarm Recorder


Currently out of stock.

SAR-713 is an advanced technology seismic alarm recorder provided by ICP DAS with a tri-axial MEMS accelerometer and acquires vibration signal by 100Hz sampling rate. It can be used to establish a complete earthquake warning system to prevent any further significant damages caused by. SAR-713 is not only a seismic switch inclusive of 2 digital outputs for emergency security measures of facilities or staffs but also an earthquake data recorder for research analysis. It can real time display maximum intensity according to CWB (Central Weather Bureau, Taiwan) or GB/T 17742-2008 (China) earthquake intensity standard, maximum vector, instant tri-axial acceleration, etc. In the meanwhile, it also supports NTP to keep clock on time and offers both MB/TCP and MB/RTU server for easily connection to host PC, PLC, HMI or SCADA.
