Seismic Instrument - SE3NT Microfractures Seismic Surveying System

Function:
Microtremor could be divided into two types: natural sources and man-made sources.
Natural sources of microtremors arise primarily from wind, ocean waves, volcanic activity, tectonic activity, surface rock migration .
Man-made sources of microtremors primarily arise from means of transportation, machinery, production, and artificial fracturing and blast mining.
SE3NT Microtremor Monitoring System is specifically developed for the monitoring and testing of various Microtremors , widely used in environmental disaster monitoring, microtremor exploration Etc.
The SE3NT is composed of the wireless acquisition unit (RSU), on-site substation (CSU), and remote control host computer (KCU).

Application:
Building and structure seismic evaluation and design , foundation classification, and foundation improvement , landslide monitoring , geothermal surveying , illegal mining surveillance, goaf investigation, hydraulic fracturing , carbon dioxide sequestration monitoring, orebody water migration etc.
