Quick Details
Specifications
Purposes:
It is used for deep seismic survey and advanced prediction, natural earthquake prediction monitoring and pulsant microseism measurement of bridge, dam, road and others as well as safety monitoring.
Characteristics:
High consistency in parameters, secure structure, good waterproof sealing, separate output of each component signal, high sensibility, low distortion, reasonable damping coefficient and high resolution; be able to meet technical requirements for multi-component seismic data collection.In conjunction with related instruments, this product series has been extensively used in the artificial seismic exploration for seismogenic structure in the earthquake dangerous zone in southeastern part of Gansu province, China and in the exploration for active fault in Xi'an city as well as in the exploration for the refined structure of lithosphere in the orogenic zone of Yin mountain and for the deep dynamic process.This product series also has been extensively used in national key projects, such as 863,305,973 and others, obtaining useful data information forChina's earthquake monitoring.
