Product Description

Main Applications

  • DZS-1 Deep Digital      Seismograph is a kind of 3D data acquisition device. Mainly utilizes      explosion and huge seismic wave to detect the characteristics and      properties of crustal deep structure; microseismic detection can also be      used in the research of natural earthquakes, 3D seismic survey of oil      field gas, etc, especially for long time unattended testing 
         System consists of data acquisition device, zero time receiver and      built-in geophone. Reflection and Refraction Exploration: Bedrock embedded      depth, shape and regularities of distribution research, hydrological and      engineering and environmental geological basic investigation.

  • Main Features

  • Timing power-on for data      acquisition and power-off upon completion, automatic data storage

  • GPS time service,      geographical location targeting

  • 3D Observation

  • 32-bit A/D converter,      high precision and high dynamic range can be reliably guaranteed

  • Low-noise design, system      noise is lower than 1μV

  • PDA or laptop computer      operation

  • Industrial CF card data      storage, safe and reliable

  • Small-sized, water-proof,      shock-proof, anti-interference

  • Main Technical Specifications

  • Weight: 5.7 kg

  • Starting-up timing range      is 7 days maximum. Maximum 30 power-on / power-off time intervals in      duration.

  • Power Supply: Use lithium      cell for power supply. Can meet normal working power supply within 7 days      for whole machine; daily time span for data acquisition is calculated as      15 hours. Regular starting-up and shut-down timing can be adopted.      Power-on for sampling when required, power-off upon sampling completion.

  • Documentation: One data      file can be formed at each sampling, and every file contains the following      texts: instrument number, station index number, sampling rate,      amplification times, time synchronization time before GPS, sampling stat      time, sampling stop time, synchronization time after GPS, GPS latitude,      GPS longitude, GPS elevation, voltage before lithium cell, voltage after lithium      cell, sampling point data.

  • Length of Data File Name,      8-Bit: The first 6 digits for station index number, the 6 digits for file      name (01, 02, ^30)

  • Development of PC      software sampling VC 6.0, which can be used for WINXP system

  • Adopt USB 2.0 interface      for data transmission with PC

  • With PDA, easy for field      work; PDA is to complete parameter setting of field work (sampling time      synchronization, time synchronization, GPS information acquisition and      input, sampling time interval setting, etc.)

  • Both PC and PDA have      functions for clearing data on FD card

  • Built-in Geophone: 2Hz      Ground Three-Component Geophone, Qty: 1
