Seismic Alarm Recorder with Metal casing

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 and urgent to prevent any further significant damages. SAR-713 is not only a seismic switch inclusive of 2 digital outputs for the security 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. Besides, SAR-713 also supports NTP function to keep internal time within 1 second accuracy. In connectivity, SAR-713 offers both MB/TCP and MB/RTU server for easily connection of host PC, PLC, HMI or SCADA and also provides active connection to host MB/TCP server ability which is useful to deploy at environment without real IP.
