DZQ 48 High Resolution Seismograph is a real 24-bit digital seismic instrument of our factory, produced on the basis of DZQ24

Description

DZQ 48 HighResolution Seismograph is a real 24-bit digital seismic instrument of ourfactory, produced on the basis of DZQ24 seismograph (The Third Prize of NationalScience and Technology Progress Award in 2002) and combined with China nationalsituation to work under a new type Chinese WINXP system. Our many years of bothdesign and manufacturing into the valuable experience of seismic instruments,also absorb today's advanced electronic technologies and design concepts, it isa leading seismograph multi-function, high accuracy, high speed, highreliability, good man-machine interface features and scalability. Instrument canbe used a hammer, electric spark or explosion as the excitation source, withexploration depth from a few meters to a thousand meters; also delay functioncan be used to obtain Department of stratum deeper underground seismic data.Applicable Methods are: Reflection, refraction, surface wave exploration, piletesting, microtremor measurement, high-density seismic imaging, vibrationtesting, measurement and shear-wave seismic exploration methods, widely used inwater conservancy, electric power, railways, bridges, urban construction,transportation and other areas of engineering geological exploration, alsoapplies to oil, coal, uranium mining and groundwater exploration and otherfields.

MainApplications

Reflectionand Refraction Exploration: Bedrock embedded depth, shape and regularities ofdistribution research, hydrological and engineering and environmental geologicalbasic investigation.
Surface WaveProspecting: Cover layer investigation; weathering zone investigation;underground cavity and diseased geologic body survey; subgrade, levee, slopedisease investigation.
High-densityMulti-wave Seismic Imaging: Cavity investigation of ground base and subgrade(roadbed), cave surveying, etc.
QualityInspection of Civil Engineering; Bridge pier and building pile foundationdetecting, etc.
SafetyEvaluation of City Blasting Vibration: All kinds of safety monitoring ofblasting vibration.
Shear WaveVelocity Test: Measurement of rock mass elasticity parameters,etc.

MainFeatures

Adopt thelatest high-speed, high-precision real 24-bit A/D converter. Maximum samplinginterval for 48 channels in simultaneous sampling is 31.25us, reachinginternational advanced level.
Maximumsampling interval for single channel is up to 10us.
Not only usethe advanced wave filter with ultra-low distortion performance, better than 120dB, with external suppression (cut-off frequency automatically changes withsampling frequency); meanwhile, various digital wave filters (high, low, bandpass wave filters) are set in the software, with their cut-off frequency beingset artificially.
Brand-newoverall structure design, which allows more reasonable view to facilitate theoperation.
Can easilycomplete seismic data acquisition, and data processing
Supportcoverage measurement;
Providedwith overlaying switch and overlaying cable manufactured by our factory, theapplication in various reflection, refraction, reflex measurement for fieldexploration can be facilitated, thus greatly improving the efficiency of fieldwork.
DZQ48high-resolution seismograph can support 12-channel and 24-channel overlayingmeasurement without external configuration
Built-inunique instrument detection system. Self-checking acquisition, data computing,self-checking report can automatically generated the output.
Fieldmake-and-break test for geophone and jug lines, full waveform noisemonitoring
Supportmultiple (at Windows interface) processing software: Superficial reflexprocessing, 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 withparameters
