Product Description Product DescriptionGD-1C Earth Pulse Seismic Vivration Mesurement Nodal SystemNodal system is a seismic data acquisition system by using seismic nodes. Compared with traditional cable based seismic systems, nodal technology allows for the rapid deployment, recording, and downloading of seismic data surveys. Besides, it is also light-weight, battery-powered and more easier to install. More and more people choose to use seismic nodals due to its convenience and multiplex functions.Features & FunctionFeatures: * No connectors* Wireless harvesting* Wireless charging* Bluetooth QC* High resolution data ±10μs* IP68 high-level water level proof* Only 580g light-weight* GPS/BDS positioning and timing* 25 days @2ms 50 days segmentedFunctions:* Reduce the difficulty forseismic exploration production, greatly improve the efficiency andlower the cost for project* Automatic deploy and retrieve* Harsh environments* Greatly improve thedynamic range rather than other equipmentTechnical SpecificationsPhysicalNo.ItemParameter1Weight580g2Size55mm x 55mm x 148mm(Without Spike)3Working Temperature-40oC to +70oC4WaterproofIP685Working Time @ 25 oC25 days @2ms 50 days segmented (12 hours ON / 12 hours SLEEP)6Charging Time3.5 hoursInstrument7Number of Channels18Sampling Rate0.25ms,0.5ms,1ms,2ms,4ms9Preamplififier Gain0-24dB(6dB steps)10Low Cut Filter1Hz,DC removed or Disable11Anti Aliasing Filter206.5Hz@2ms(82.6% Nyquist frequency) optional maximum phase or mimium phase120dB @ Max Input2.5VpeaK13Equivalent Input Noise @ 12dB0.5uV@0.25ms / 0.2uV@2ms / 0.14uV@4ms14Instantaneous Dynamic Range @ 12dB118.9dB@0.25ms / 126.8dB@2ms / 130dB @4ms15Total Dynamic Range150dB16Time Accuracy±10μs17Internal StorageExtended from 8GB to 32GB18Built in GPSGPS, BDS, GLONASS,GNSS(Concurrent reception) are used for timing and positioningGeophone19Optional Geophone5Hz20Natural Frequency5±7.5%21DC Resistance1850±5%22Sensitivity80±5%23Damping0.6±7.5%24Distortion<=0.1%25Aliasing>=170About 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.
