12 / 24 Channel Seismograph Engineering Seismic Wave Tester Steel

Engineering Seismic Wave Tester 12 And 24 Channel Seismograph

Introdution

Engineering seismograph is the third generation instrument, which support window 8 system, and features multi-function, high-precision and stability. Seismic source for testing is from hammer, electric spark or explosion for hundreds meter depth. It applies for seismic surveys, as sheared wave velocity test, surface wave exploration, pier foundation test, ground micro-tremor measurement, seismic imaging, shake measurement, refraction or reflection survey and so on.

If the unit has been immersed into well when operating, aerate pump. Till its indicator rises to 0.5Mpa, you can stop inflating (also a pressurized-gas cylinder is available for filling).

The means of cable connection of the geophone to sub box or media cards: without any external linkage, the red and black line of cable link to the positive and negative on the vertical geophone, the yellow and green link to level orientation one, and blue and white line link to another. If the geophones connect with 27 cores plugs, the pin 1 and 2 link to the vertical geophone, the pin 3 and 4 to first level geophone from the top down, pin 5 and 6 link to another level geophone. In this case the pin 1,3 and 5 are positive poles of the geophones and pin 2,4 and 6 are negative poles. If the geophones connect to a sub box with a Q9 card, the Z orientation of sub box is vertical geophone, Y orientation is first (from the top dowm) level geophone and X orientation is second level geophone. If the geophones connect to a sub box with a three colors plugs, Z orientation (red) link to the vertical geophone, Y orientation (yellow) link to the first level geophone and X(blue)link to second geophone.
