Dzq 24 48 High Resolution Seismograph Shallow Layer - China

price: contact company for price

Specifications

DZQ 48 High Resolution Seismograph is a real 24- bit digital

seismic instrument of our factory, produced on the basis of

DZQ24

Description

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.

Main Applications

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.

Main Features

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 level.

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.

DZQ48 high- resolution seismograph can support 12- channel and

24- channel overlaying measurement without external

configuration

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

Support multiple ( at Windows interface) processing software:

Superficial reflex processing, refraction, surface wave

shear wave package, blasting, pulsating, high- density

seismic imaging processing software

Clock: Annual timing clock, file recording time will be

stored in along with parameters
