Seismography Earthquake 12/24/48/96 Channels Seismic Reflection & Refraction Survey Seismograph¹

Product Description Products DiscribtionWZG Series Earth Seimic Reflection & Refraction Seismograph EquipmentIn order to respond to ground noises and shaking such as caused by quakes, volcanic eruptions, and explosions, we need professional geophysical instrument-seismometer. It can record the motion of ground during an earthquake, which is very small vibration. Depends on the the different usages, 12/24/24/48/96 or more seismic cables may be needed for reflection/refraction survey. Based on transient multi-point Rayleigh wave exploration, shallow reflection/refraction measurement, wave speed shear wave measurement, pile foundation meaurement and many other surveys WZG can do, it is widely applied in building base, doadben and foudation engineering detetion, tunnel construction detection, large and medium reservior monitoring, bridge engineering inspection and many other aspects.Features & FunctionFeatures:* Quick sampling: true 24 A/D, fatest sampling interval-50μs* Perfect reproduction of the original signal: superior amplitude and phase coherence, ultra-low distortion performance, advanced high-cut filter with  better than 72dB out-of-band suppression* High-speed data transmission: instantly complete the transmission of large quantities of seismic data; in the process of background noise                  monitoring, it can accept the trigger signal at any time and enter the formal sampling process.* Powerful software: advanced graphic technology; screen can display 128 channels wave train; convenient amplitude equalisation display mode; at a glance static time markers and so on.* Flexible configuration and easy expansion: users can choose DOS or WINDOWS processing software according to their own situation, and can also upgrade the instrument to a 48-channel seismometer by purchasing a data acquisition plug-in board and software.* Support for coverage measurements: by using our company's PZF series of electronic cover switch, it will be very convenient to achieve a variety of field coverage measurements, greatly improving the efficiency of field shallow reflection seismic exploration operations.* Great durability: outstanding resistance to vibration, moisture and dust.Functions:* Inspection of foundations, road foundations and foundation works:1. Foundation and roadbed cavity surveys and lava exploration2. Stratification of the quaternary cover3. Classification of foundation soil types and investigation of diseased geological bodies4. Investigation of the physical properties of the foundation geotechnical media5. Effectiveness of foundation reinforcement and 1uality inspection of backfill compaction of road base6. Investigation of bedrock burial and hidden geological formations* Tunnel engineering inspection:1.Tunnel route survey and classification of cavern surrounding rock2. Concrete lining quality checks3. Undertunnelling and pre-tunneling4. Vibration monitoring* Operational observation of large and medium-sized reservoirs:1. Detection of dyke hazards2. Measurement of siltation in reservoirs and checking the effectiveness of silt removal3. Construction inspection of large and medium-sized water hub berm throwdowns* Bridge Engineering Inspection:1. Investigation of abutment foundation types2. Inspection of concrete quality of bridge abutment pile foundation3. Bridge vibration monitoring* Environmental and geological hazards detection andevaluation:1. Investigation of landslides, karst, mudslides, air-mined areas, active fracturesTechnical SpecificationsWZG-24/48C Seismograph Technical SpecificationsNo.ItemParameter1Channels6/12/24/48/96 channels optional2Sampling sites1024, 2048, 4096, 8192, 163843Sampling Rate10μs,25μs,50μs,100μs,200μs,500μs,1ms,2ms,5ms,10ms,20ms4A/D coverter24-bit5Signal stack and amplification32 bit6Dynamic range144dB7Frequency pass bands0.1Hz~4000Hz8Noise1μV(full-frequency)9Amplitude consitency±0.2%10Phase consistency±0.01ms11Distortion± 0.05%12Lapse-time0~9999ms13Input impedance20K14Interchannel crosstalk suppression≥90dB15Low cut filter steepnessSoftware filter16High cut filter steepnessBetten than 72dB 1750Hz trap40dB18Data formationSEG-2 19  Processing software(optional)Shallow reverse processing softwareRayleigh surface wave processing softwareGround pulse collection and processing softwareMulti-electrode high-resolution profile measurement and processing software 20Working temperature-10oC~+50oC 90%RH21Storage temperature-20oC~+60oC22Weight 12Kg(WZG-24C); 13Kg(WZG-48C)23Dimension 470mm × 357mm× 176mmBasic ConfigurationNo.ItemUnitQuantity1WZG-24/48C mainframeSet12multi-electrode cablePiecePending on channels3Extension cablePiecePending on channels4Geophone(frequency optional)PiecePending on channels5Penning slabSet16Trigger swithPiece17Packaging boxPiece1Products DetailsAbout UsChongqing Gold Mechanical & Electrical Equipment LtdWe are specializes in manufacturing and development of high-resolution geophysical instruments such as Resistivity Meter, IP instrument, Resistivity Imaging, Seismic instrument, magnetic instrument, borehole camera, borehole logger and drilling equipment ( core drill rig, water well drill rig,engineering drill rig, anchor drilling rig and so on.
