Offer aidu A-DZQ24D high resolution seismograph 
Posted by shanghai aidu industrial co.,ltd  [Silver] on 14/05/2012
We are one of the largest professional and reliable manufacturer of geophysical prospecting instrument in China,dealing with this line for 10 years, such as geophysical instrument, resistivity meter, resistivity IP and SP system, resistivity, IP, SP, TEM survey, magnetometer, seismograph, gravity meter, proton magnetometer, water detector,mineral prospector,drilling equipment, and element analyzer etc.

Simple introduction:
A-DZQ24D high resolution seismograph is our newly developed real 24 digits equipment worked in WINXP system. It is our leading seismograph having many features: multi-functions, high accuracy, high speed, high reliability, good human-machine interface function and expansibility. It can use hammer, electric spark or explosion as inspiring source, the prospecting depth ranges from several meters to thousands of meters. You can use time delay function to gain more deep seismic information, and the applied methods are: reflection, refraction, surface wave exploration, pile testing, earth pulse measurement, high density earthquake imaging, tremor survey and shearing wave testing etc. It is widely used in the engineering geological prospecting of water conservancy, electric power, railway, bridge, city building and traffic etc., also resource survey in oil, coalfield, uranium ore and underground etc.

Main applications:
1. Refraction & reflection survey----- Bedrock layering and buried depth, hydraulic engineering advanced geological foundation investigation etc.
2. Surface wave investigation-------Overburden layer stratification survey, weathering zone investigation, underground cavities and disease geologic body prospecting, roadbed, road-dam, slop damage survey and so on.
3. Multi-wave high density seismic imaging------ Foundation and roadbed cavities prospecting, karst survey etc.
4. Field aseismic design survey-------- High-rise building and bridge vibration detection, basis investigation and safety estimation.
5. Civil engineering quality inspection------ Bridge piers and building piles detection etc.
6. City vibration and explosion safety estimation------Various explosion and vibration safety monitoring etc.
7. Shear wave measurement------Rock mass elasticity and mechanical parameters measurement etc.

Main parameters:
1. Simulation channels: 24 channels (1, 2, 3, 4, 6, 12, 24, 48 channels working modes optional)
2. Sampling rate: 10μs, 31.25μs, 62.5μs, 125μs, 250μs, 500μs, 1ms, 2 ms, 4 ms, 8 ms, 16 ms, 32 ms~400 ms some etc.
3. Sampling points: 512, 1024, 2048, 4096, 8192, 16384 etc, the longest record: 32768.
4. Preamplifier gains: each 6 channel as 1 group, 64 times (36dB), 16 times(24dB), 4 times(12dB) and 1 time optional;
5. A/D transformation: newest & super high speed Σ-Δ 24 bites A/D transformer.
6. Anti-alias filter: Auto tracking as sampling rate; -3dB(when at sampling rate 0.216 times), below to 120 dB; also matches all kinds of digital filter, critical frequency point(at -3dB) set manually upon the requirement;
7. Frequency response range: 0.1 to 4 KHz.
8. Noise: Less than 1 μV(in full frequency status)
9. Delay time: 0 to 9999 ms.
10. Amplitude inconsistence: superior to±0.02%
11. Phase consistence: Superior to ±0.01ms
12.Dynamic Range: superior to 144dB。
13. Signal superposition reinforce: 32 bites
14. Operation system: WinXP
