We developed a prototype of a new P-wave sparker borehole source and digital hydrophone string.

SBS1000 Magnum | P-Wave Sparker Borehole Source

The borehole source SBS1000 Magnum is designed for P-wave tomography between boreholes up to 1000 m depth. The source consists of three parts housing the complete high-voltage power supply for charging up to about 3 KV. The source can be connected to a GO-4 cable head and a standard logging unit (4-conductor cable). Th

We have developed a novel wireless trigger unit (WTU1) which is used to replace trigger cables if e.g. roads or rivers prevent a continuous seismic measurement. This wireless trigger unit WTU1 works with nearly all impulse sources including sledge hammers and have a antenna range of 18 metres. 

The trigger unit WTU1 consists of two boxes which include the sender and the receiver unit. The sender will be connected to the source and the receiver to the seismograph. Both the sender

The seal "Innovation through Research" has been awarded to Geotomographie by the Stifterverband/Germany. The Stifterverband honors researching organizations for their special communal and societal responsibility with the quality seal. The Stifterverband focuses its efforts primarily on the fields of education, science and innovation. To date, it is the only organisation in Germany to engage in holistic work in all three areas, with projects that build on one another with synergistic effect.</

The new version of the vibrator source Elvis is now on the market. The Elvis VII provides a higher peak force of 1100 N and frequencies between 20-240 Hz for both, P- and S-waves. An investigation depth of up to 300 m (and more) for P-waves and up to 200 m (and more) for S-waves can now be reached depending on the geology.

The vibrator source Elvis VII is used to generate P- or S-wave sweep signals. An adjustable pneumatic s

The new hydrophone string BHC5 replaces the older unit BHC4.

BHC5 - Hydrophone String
The new BHC5 amplifier boards are now equipped with an additional internal test function. The test function outputs a synthetic signal on each channel where the amplification factors can be evaluated. This allows a quality check of the hydrophones at any time.

Alternatively to the digital MBAS-D system the analog version of a borehole geophone string (MBAS-A) is available on the market.

MBAS-A - Analogue Multistation Borehole Aqcuisition System
The instrument can be used for S-wave borehole tomography or downhole surveying. It consists of up to eight geophone stations each equipped with a tri-axial sensor. The string is fully water proof and can be used to receive P- and S-waves in dry or water filled boreholes. Ple

We will release our new P-wave sparker borehole source and digital hydrophone string soon.
