24Channel Seismic Refraction Equipment for Geophysical Exploration
Seismic refraction equipment is used to measure and map subsurface properties of the earth, including its structure, composition, and density. It involves the use of sensors or detectors that record sound waves or seismic waves that travel through the earth's subsurface layers. The equipment typically consists of a seismic source, such as a sledgehammer or explosive charge, and one or more sensors or detectors, such as geophones or hydrophones, which are placed on the surface or in boreholes to record the waves. The data is analyzed to create a cross-sectional view of the subsurface layers, which can be used to locate and identify geological features, such as faults, aquifers, and oil and gas deposits.
The features of seismic equipment vary depending on the type and purpose of the equipment. Some common features include:
1) Source: The source is the device used to create seismic waves. It can be a Hammer, spark or explosion
2) Recording System: The recording system is used to collect, store, and process the seismic data. It can be a computer-based system that digitizes and displays the data in real-time.
3) Data Processing Software: Data processing software is used to analyze and interpret the seismic data. It can be used to create images and maps of the subsurface rocks and formations.
Overall, seismic equipment is a crucial tool for exploring the subsurface and understanding the geological formations beneath our feet.
