Product Description

Refraction Seismic Survey Seismograph Surface Wave Seismic Survey Equipment for Civil Engineering and Subsurface Mineral Exploration

Product Description

Seismic survey equipment is used to study the subsurface of the Earth by measuring the response of seismic waves (usually sound waves or vibrations) as they travel through different geological layers. This type of equipment is crucial for industries like oil and gas exploration, environmental studies, and geotechnical investigations.

Working Principle:

Seismic surveys work by generating seismic waves using a source (like dynamite or vibrators) placed on the Earth's surface or in the subsurface. These waves travel through the ground and are reflected by different geological layers. The reflected waves are captured by geophones or accelerometers placed on the surface. The data is then analyzed to create a map of the subsurface structures.

Features of Refraction Seismic Survey Seismograph Surface Wave Seismic Survey Equipment for Civil Engineering and Subsurface Mineral Exploration

• Fast sampling----true 24-bit A/D, minimum sampling interval: 50μs for 24 channel.
• Rendering original signal perfectly----perfect amplitude and phase consistency, low distortion, band outside shearing better than 72dB (shearing frequency point changing with sampling frequency automatically, removing alias completely).
• High-speed data transfer----Transmitting data by USB port between internal industrial PC and data collector. Advanced hardware make the sampling and transferring data simultaneously.
• Powerful software function----sampling software under WINDOWS supports all kinds data acquisition of seismic methods (shallow reflection, refraction, secondary wave speed testing, micro-seismic survey, high density image and other application). Data displaying and rolling screen are very quick by using advanced graphic technique. Channel on the screen is adjustable, 128 channel maximum.
• Industrial PC configuration----PIII 533MHz, 128M memory, 40G harddisk, interior CD-ROM, 800 600TFT true color LCD, Chinese character tablet, small keyboard, photoelectric mouse, 32M Flash-Memory, double serial port, one parallel port, double USB port, mouse port, keyboard port. Seismic data collecting and transacting is convenient.
• Configuration and expansibility----DOS or WINDOWS software available. Instrument can be upgraded to 48 channel seismograph by purchasing data collecting card and software
• Stack survey support----Combined with our WZKD-1 electric stack switcher, stack survey can be realized efficiently.
• Reasonable configuration---- anti-shake, damp-proof and dust-proof design.
