Seismic Equipment For Sale Seismic Seismograph
DZQ 48 High Resolution Seismograph is a real 24-bit digital seismic
instrument of our factory, produced on the basis of DZQ24
seismograph (The Third Prize of National Science and Technology
Progress Award in 2002) and combined with China national situation
to work under a new type Chinese WINXP system. Our many years of
both design and manufacturing into the valuable experience of
seismic instruments, also absorb today's advanced electronic
technologies and design concepts, it is a leading seismograph
multi-function, high accuracy, high speed, high reliability, good
man-machine interface features and scalability. Instrument can be
used a hammer, electric spark or explosion as the excitation
source, with exploration depth from a few meters to a thousand
meters; Also delay function can be used to obtain Department of
stratum deeper underground seismic data. Applicable Methods are:
Reflection, refraction, surface wave exploration, pile testing,
microtremor measurement, high-density seismic imaging, vibration
testing, measurement and shear-wave seismic exploration methods,
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.
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
Adopt the latest high-speed, high-precision real 24-bit A/D
converter. Maximum sampling interval for 48 channels in
simultaneous sampling is 31.25us, reaching international advanced
Maximum sampling interval for single channel is up to 10us.
Not only use the advanced wave filter with ultra-low distortion
performance, better than 120 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.
Can easily complete seismic data acquisition, and data processing
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.
