Engineering Digital Seismograph Ground Pulsation Tester Detector WZG-24C
The WZG series of multi-channel digital high-resolution seismographs independently developed by our company are rich in functions, adopt distributed design, TCP IP network cascade, and the channels can be expanded to 2048 channels at most. The built-in software of the instrument is fully functional, providing reflection, refraction, surface wave exploration, ground pulse measurement, seismic imaging, vibration monitoring, seismic CT, rapid water seismic and other functions. The instrument is also equipped with two control modes: knob and touch screen, which are simple and fast to use. The products are widely used in seismic exploration in the fields of water conservancy, electricity, railways, bridges, urban construction, transportation, etc.
Product Applications
- Seismic reflection, refraction, surface wave exploration
- Seismic CT
- Earth pulse measurement
- Seismic impression
- Wave velocity logging
- Vibration monitoring
Product features
High sampling rate
Minimum sampling interval of 5us per channel
Large dynamic range, high signal-to-noise ratio
High resolution, high fidelity, 130dB large dynamic range, good channel consistency, high signal-to-noise ratio, background noise ≤0.1uV
Channel expandable
Based on TCP/IP network distributed design, 24 seismographs are cascaded through network interface and can be expanded
Adapt to harsh working environment in the field
The main control system adopts military notebook, which adapts to harsh working environment in the field and supports the deployment of three-dimensional observation system in complex areas
