DC-4500 Seismoelectric Ground-flow Locator
A seismoelectric recording system. Consist of seismoeletric signal data pre-adjusters and computer control. A military grade computer used as the control with built in GPS.
Output noise: 20Vp-p at 90 db gain
Work time: 5 hours
Work temperature: -20 to 60 degrees C
Stacking Trigger Accuracy: 0.05 of sample rate
Operating System: window XP
Bundled Software: Data collection
In the general survey, unit obtains both the seismic signal, and the combined seismoelectric signals. The seismoelectric survey monitor receiver is used in a civil engineering ground water related survey.
Seismoelectric electrodes, geophones, cable, connectors, etc.
The nature of generation of the Seismic source is critical to the seismic and seismoelecric survey results.
The sledge hammer is popular for most shallow seismic refraction surveys using a multichannel seismograph, but the range of impact is limited. The "buffalo gun" has a wider and deeper impact range of acoustic energy and has been used in the field with great success with the seismoelectric method.
The main problem with buffalo gun is its loud sound blast, which may restrict its use in populated areas. We have developed a soundless device in the buffalo gun,and It works very well with the same seismic impact using a 12 gauge shot gun cartridge.
Weight Drop Seismic Source Survey
With some special requirements of our clients, we also have tested weight drop seismic source methodology of generation in the seismoelectric survey.
The tested data shown the one drop energy of A200 P/S Hammer is similar to a 2.5 inch 12 gauge cartridge acoustic impulse. However, the relative cost of this weight drop seismic source is much more than using a buffalo gun methodology.
