DZQ Series Seismograph

Descripción del producto

DZQ high resolution seismograph can use a hammer, electric spark or explosion as the excitation source, with exploration depth from a few meters to thousands meters, also delay function can be used to obtain deeper underground bottom layer seismic data. widely used in water conservancy, electric power, railways, bridges, urban construction, transportation and other areas of engineering geological exploration, also applies to oil, coal, uranium mining and groundwater exploration and other fields.

Main Application：

• Reflection and Refraction Exploration: Bedrock embedded  depth, shape and regularities of distribution research, hydrological and engineering and environmental geological basic investigation.
• Surface Wave Prospecting: Cover layer investigation; weathering zone investigation; underground cavity and diseased geologic body survey; subgrade, levee, slope disease investigation.
• High-density Multi-wave Seismic Imaging: Cavity investigation of ground base and subgrade (roadbed), cave surveying, etc.
• Quality Inspection of Civil Engineering; Bridge pier and building pile foundation detecting, etc.
• Safety Evaluation of City Blasting Vibration: All kinds of safety monitoring of blasting vibration.
• Shear Wave Velocity Test: Measurement of rock mass elasticity parameters, etc.

System Components:

The system consists of acquisition system and processing system

Acquisition system concludes seismograph, geophones, hypocenter, cable and other related accessories,

Processing system includes various methods explained processing software.

Features and Functions

• Adopt the latest high-speed, high-precision real **-bit A/D converter. Maximum sampling interval for *8 channels in simultaneous sampling is *1.*5us, reaching international advanced level.
• Not only use the advanced wave filter with ultra-low distortion performance, better than **0 dB, with external suppression (cut-off frequency automatically changes with sampling frequency); meanwhile, various digital wave filters (high, low, band pass wave filters) are set in the software, with their cut-off frequency being set artificially.
• Brand-new overall structure design, which allows more reasonable view to facilitate the operation.
• Military Grade PC**4 Control Computer P3. Memory: **6MB; 4GB electric hard disk, provide with USB, VGA, PS/2 keyboard interface
• Based on WinXP operating system, humanized interfacial design, making the system safer and easily use.
• Adopt engineering plastic cabinet structure design, more suitable for field application
• Support coverage measurement. Provided with overlaying switch and overlaying cable manufactured by our factory, the application in various reflection, refraction, reflex measurement for field exploration can be facilitated, thus greatly improving the efficiency of field work.
• Built-in unique instrument detection system. Self-checking acquisition, data computing, self-checking report can automatically generated the output.
• Field make-and-break test for geophone and jug lines, full waveform noise monitoring
